Sample Data Installations

As long as you follow the ANSI/TIA/EIA-568-B Standard, most of your communications infra-structure will be pretty similar and will not vary based on whether it is supporting voice or a specific data application. The horizontal cables will all follow the same structure and rules. However, when you start using the cabling for data applications, you’ll notice some differences. We will now take a look at a couple of possible scenarios for the usage of a structured cabling system.

The first scenario, shown in Figure 7.14, shows the typical horizontal cabling terminated to a patch panel. The horizontal cable terminates to the 110-block on the back of the patch panel. When a workstation is connected to the network, it is connected to the network hub by means of a RJ-45 patch cable that connects the appropriate port on the patch panel to a port on the hub.

The use of a generic patch panel in Figure 7.14 allows this cabling system to be the most versatile and expandable. Further, the system can also be used for voice applications if the voice system is also terminated to patch panels.

cabling system

Another scenario involves the use of 110-blocks with 50-pin Telco connectors. These 50-pin Telco connectors are used to connect to phone systems or to hubs that are equipped with the appropriate 50-pin Telco interface. These are less versatile than patch panels because each connection must be termiated directly to a connection that connects to a hub.

In past years, we have worked with these types of connections, and network administrators have reported to us that these are more difficult to work with. Further, these 50-pin Telco conectors may not be interchangeable with equimpent you purchase in the further. Figure 7.5 shows the use of a 110-block connecting to network equipment using a 50-pin Telco connector.

A final scenario that is a combination of the patch-panel approach and the 110-block approach is the use of a 100-block patch cables (such as the one shown previously in Figure 7.9). This is almost identical to the patch-panel approach, except that the patch cables used in the telecommunications closet have a 110-block connector on one side and an RJ-45 on the other. This configuration is shown in Figure 7.16

The previous examples are fairly simple and involve only one wiring closet. Any installation that requires more than one telecommunications closet and also one equipment room will require the service of a data backboane. Figure 7.17 shows an example where data backbone cabling is required. Due to distance limitations on horizontal cable when it is handling data applications, all horizonatal cable is terminated to network equimpment (hubs) in the telecommunications closet. The hub is then linked to other hubs via the data backbone cable. Now recommend you two fiber optic patch panels, following picture shows the details.

Plus, they’re available with LC, SC or ST connections – you’ll be able to integrate any component or piece of equipment, old and new. For modular and cabinet applications, Fiberstore carries rack mounted units that easily install in standard 19″ racks, as well as fiber patch panel wall mount units that feature built-in cable management.

Physical Cable Management

The physical level of cable management covers the actual cabling itself. Using physical cable managmement systems ensures that you keep your cables in a safe, neat layout.

Because fiber optic cabling is brittle, the glass fibers within the cables can bend only so far. If they get twisted into a knot or around a tight corner, they snap like glass. Broken fiber optic cable is hard to identify, because sometimes the light still gets through just enough to work. Think of a garden hose with a kink: Some water will gets through, but in spurts versus a steady flow of water. When a fiber optic cable sometimes lets light through and sometimes doesn’t, you end up with a flaky connection that can cause all kinds of issues out on your SAN. With orderly cable placement, if a cable does ge broken somehow, it’s easier to replace it if you don’t have to fight with that giant day-glow orange spaghetti under the floor.

A good cable management system usually comes in the form of a rack or some types of 19” rackmount panels that securely hold the cabling. The rack or panels have tracks where the cables run next to or inside your equipment racks so that they can easily yet safely flow between one component and another.

Some of these systems come with patch panels, which have rows of fiber optic ports on the front that allow you to connect the cables that come out of components or other patch panels. Patch panels give you a prelabeled system you can use to interconnect your components or other patch panels. Patch panels give you a prelabeled system you can use to interconnect your components without having to run new cabling every time you want to add or change something in your SAN layout. With patch panels, you hook up all the connections on each of your components to the ports on the panels. You run the fiber-optic cables from your server’ HBAs to a patch panel as well. All cabling is run en masse to the backs of these centrally located panels. When you want to connect components to your servers, you use short fiber optic cables (patches,) usually less than 3 meters long (abount 10 feet), to patch the ports from your arrays to the ports of your swiches to the ports for your HBAs.

Figure 1 shows how a typical patch panel solution connects your SAN components without requring you to lift a floor tile or roll a spoll of cable across the floor. Another benefit of using a patch panel is that running fiber-optic cable on a one-by-one basis can be very expensive. In a fewer times electricians have to come in to put in more cables, the better. Running a group of cables in one shot from the very beginning is much cheaper and faster than doing it one by one later.

fiber optic patch panel

Patch panel systems also make things very flexible. Now that you have all the endpoints of your SAN components in one place, you can easily control what talks to what by using the short, easy-to-manage patch cables. Following is the diiferent ports example of fiber optic patch panel, there are 12 port fiber patch panel, 16 port patch panel, 24 port patch panel.

Fiber Enclosure Systems and Patch Panels

As previously mentioned, fiber optic cables have a very small core that can be easily damaged if not protected properly. Also, to conform to the minimum size of a fiber optic loop and not violate the critical angle, we need to have a way to keep excess fiber optic patch cables, as well as terminated building fiber, neat and protected from damage. Fiber-optic enclosures and patch panels allow the cable installer to protect the delicate fiber cable from damage, while still making it useable for the network adminstrator. A commmon device that is used as a fiber-optic cable enclosure is called a Lightguide Interconnection Unit (LIU). The LIU provides a location to terminate individual fiber-optic strands into a patch panel, which will be discussed in the next section. An LIU is generally made of galvanized steel that is then power-coated to provide durability. Most major LIU manufactures make their devices 19 inches wide so they can be installed in a normal communications rack. If the LIU is to be located in an enviroment where there is a risk of moisture or corrosives, the LIU can be sealed with gaskets to make it virtually waterproof. Most LIUs have swing out trays in the front and the back to provide easy access to the patch panel located inside. Also, most LIUs provide a place to route excess cable to ensure that all loops are of a minimun diameter, so the cable will not get damaged and maximum ligth can traverse the cable.

Patch panels for fiber-optic cables are usually installed into the LIU. Because the core and cladding of two fiber optic cables that are to be joined together must match perfectly, the patch panel must be manufactured to exact specifications and some standard type connector must be used to ensure a good fit. (Fibe-opticon connectors are discussed in the next section.) Another patch panel issue deals with attenuation. Remember from the previous discussion that when you splice or join a fiber optic cable, you can introduce additional ligth loss or attenuation. The same holds ture for the fiber optic patch panel. The connectors on the patch panel should identify total loss at various wavelegths, and these losses should be added to any other cable loss on that particular cable to ensure compliance with standards and good operation of the fiber optic cable. Now we will introduce you two fiber optic patch panel in the market, they are 12 port fiber patch panel, 24 port patch panel from our store.

One of Most Major applications of Optic Fiber—FTTH

FTTH (Fiber To The Home), it is Fiber Optic Patch Cables directly to the home. Specifically, FTTH optical network means (ONU) installed in the home or business user of the user, the optical access network is a series of optical access the user application type except FTTD (fiber to the desktop) closest outside. FTTH technology is characterized by significant not only provides greater bandwidth, but also enhanced network data format, speed, wavelength and protocol transparency, relaxed on the environmental conditions and power requirements, simplifies maintenance and installation.

FTTH advantage

1. FTTH is a passive network, from the central office to the user, fiber optic coupler, fiber optic passive components accounted for most of the equipment, it can be done in the middle basically passive.

2. It is relatively wide bandwidth. Large-scale use is in line with the way long distance carriers.

3. It is a direct bearing on the fiber business, so there is nothing complex issues.

4. Because of its relatively wide bandwidth, support for the agreement is more flexible.

5. With the development of technology, including point to point, 1.25G and FTTH way have developed a relatively complete function.

The optical fiber directly to the user’s home, its bandwidth, wavelength and transmission technology types are no restrictions for the introduction of new services, it is the ideal business transparent network, and it is also the ultimate way to access network development. Although the development of mobile communications at an alarming rate, but because of limited bandwidth, terminal volume can not be too large, the display screen is limited and other factors, it is still pursuing a fixed terminal performance, which is hoped to achieve FTTH. Fiber to the home’s charm lies in its great bandwidth, it is the best solution to solve from the Internet backbone to the user’s desktop bottlenecks.

FC/UPC to FC/UPC 9/125 Single mode Fiber Patch Cable

FC-FC 24 Fibers OM4 Multimode Fiber Patch Cable

FC-FC 24 Fibers OM4 50/125 Multimode Fiber Patch Cable

With the upgrading of technology, greatly reduces the cost of fiber to the home, it will soon be reduced considerably with DSL and HFC networks, which makes it possible for practical FTTH. In China, FTTH is also imperative. From 2011, in China from coastal cities to inland cities, from east to west, opened the curtain FTTH construction. You can say that FTTH is a highlight of optical fiber communication. Accompanied by a corresponding technologies mature and practical, cost closer to ordinary families can afford to reduce the level of FTTH trend is unstoppable.

Furthermore, FTTH technology is still used to solve the “last mile” problem of the information superhighway. FTTH + Ethernet over ADSL (ADSL dial-up time will be established at the highest theoretical 8Mbps download bandwidth, this bandwidth is never changed, but in fact, because the noise detection mechanism ADSL line situation is not good, if it is clearly beginning to establish a connection not reach the theoretical value, may finally be 5Mbps, this bandwidth is also not change.) and ISDN (European popular form of telephone network) transmission speed is much faster.

FTTH has been considered a rising star ultimate ideal access networks, but also broadband development. Because it can meet the diverse needs of various users. Like high-speed communications, home shopping, high-definition television, video on demand and more. The copper wire is the reluctance of the business, it is easy for FTTH. One can imagine, FTTH is to realize telephone, cable TV and Internet “triple play” the best choice.

Three Types of Cable Connectors Used in Cabling Installation Techniques

There are three types cable connectors in a basic cabling installation techniques: twisted-pair connectors,coaxial cable connectors and fiber-optic connectors. Generally cable connectors have a male component and a female component, except in the case of hermaphroditic connectors such as the IBM data connector. Usually jacks and plugs are symmetrically shaped, but sometimes they are keyed. This means that they have a unique, asymmetric shape or some system of pins, tabs, and slots that ensure that the plug can be inserted only one way in the jack.

Twisted-Pair Cable Connectors

Many people in the cabling business use twisted-pair connectors more than any other type of connector. The connectors include the modular RJ types of jacks and plugs and the hermaphroditic connector employed by IBM that is used with shielded twisted-pair cabling. Twisted-Pair Cable Connectors are used with patch panels, punchdown blocks, and wall plates. Twisted-Pair Cable connector is called an IDC, or insulation displacement connector.

Most unshielded twisted-pair (UTP) and screened twisted-pair (ScTP) cable installations use patch panels and, consequently, 110-style termination blocks. The 110-Block contains rows of specially designed slots in which the cables are terminated using a punch-down tool. When terminating 66-blocks, 110-blocks, and often, wall plates, both UTP and ScTP connectors use IDC technology to establish contact with the copper conductors. You don’t strip the wire insulation off the conductor as you would with a screw-down connection. Instead, you force the conductor either between facing blades or onto points that pierce the plastic insulation and make contact with the conductor.

Both UTP and ScTP cables use modular jacks and plugs. For decades, modular jacks have been commonplace in the home for telephone wiring. Modular connectors come in four-, six-, and eight-position configurations. The number of positions defines the width of the connector. However, often only some of the positions have metal contacts installed. Make sure that the connectors you purchase are properly populated with contacts for your application.

Common Modular-Jack Designations and Their Configuration
Coaxial Cable Connectors

Unless you have operated a 10Base-2 or 10Base-5 Ethernet network, you are probably familiar only with the coaxial connectors you have in your home for use with televisions and video equipment. Actually, a number of different types of coaxial connectors exist.

The coax connectors used with video equipment are referred to as F-series connectors.The F-connector consists of a ferrule that fits over the outer jacket of the cable and is crimped in place. The center conductor is allowed to project from the connector and forms the business end of the plug. A threaded collar on the plug screws down on the jack, forming a solid connection. F-connectors are used primarily in residential installations for RG-58, RG-59, and RG-6 coaxial cables to provide CATV, security-camera, and other video services.

F-Series Coaxial Connectors

F-connectors are commonly available in one-piece and two-piece designs. In the two-piece design, the ferrule that fits over the cable jacket is a separate sleeve that you slide on before you insert the collar portion on the cable. Experience has shown us that the single-piece design is superior. Fewer parts usually means less fumbling, and the final crimped connection is both more aesthetically pleasing and more durable. However, the usability and aesthetics are largely a function of the design and brand of the two-piece product. Some two-piece designs are very well received by the CATV industry.

N-Series Coaxial Connectors

The N-connector is very similar to the F-connector but has the addition of a pin that fits over the center conductor; The pin is suitable for insertion in
the jack and must be used if the center conductor is stranded instead of solid. The assembly is attached to the cable by crimping it in place. A screw-on collar ensures a reliable connection with the jack. The N-type connector is used with RG-8, RJ-11U, and thicknet cables for data and video backbone applications.

The BNC Connector

When coaxial cable distributes data in commercial environments, the BNC connector is often used. BNC stands for Bayonet Neill-Concelman, which describes both the method of securing the connection and its inventors. Many other expansions of this acronym exist, including British Naval Connector, Bayonet Nut Coupling, Bayonet Navy Connector, and so forth. Used with RG-6, RG-58A/U thinnet, RG-59, and RG-62 coax, the BNC utilizes a center pin, as in the N-connector, to accommodate the stranded center conductors usually found in data coax.

The BNC connector comes as a crimp-on or a design that screws onto the coax jacket. As with the F-connector, the screw-on type is not considered reliable and should not be used. The rigid pin that goes over the center conductor may require crimping or soldering in place. The rest of the connector assembly is applied much like an F-connector, using a crimping die made specifically for a BNC connector.

Fiber-Optic Cable Connectors

Fiber-optic connections use different terminology than copper based connectors. The male end of the connection in a fiber-optic system is termed the connector, in contrast to the plug in a copperbased system. The female end of the connection is termed the receptacle or adapter, in contrast to the jack in a copper-based system.

To transmit data up to 10Gbps, two fibers are typically required: one to send and the other to receive. For 40Gbps and 100Gbps over multimode, as many as 24 fibers will be required. Fiber optic connectors fall into one of three categories based on how the fiber is terminated:

  • Simplex connectors terminate only a single fiber in the connector assembly.
  • Duplex connectors terminate two fibers in the connector assembly.
  • Array connectors terminate more than two fibers (typically 12 or 24 fibers) in the connector assembly.

The disadvantage of simplex connectors is that you have to keep careful track of polarity. In other words, you must always make sure that the connector on the “send” fiber is always connected to the “send” receptacle (or adapter) and that the “receive” connector is always connected to the “receive” receptacle (or adapter). The real issue is when normal working folk need to move furniture around and disconnect from the receptacle in their work area and then get their connectors mixed up. Experience has shown us that the connectors are not always color coded or labeled properly. Getting them reversed means, at the least, that link of the network won’t work.

Array and duplex connectors and adapters take care of this issue. Once terminated, color coding and keying ensures that the connector can be inserted only one way in the adapter and will always achieve correct polarity.

The SFF Connector

As transmission rates increase and networks require the cramming in of a greater number of connections, the industry has developed small-form-factor (SFF) connectors and adapter systems for fiber-optic cables. The SC, ST, and FC Connectors shown in Table 10.5 all take up more physical space than their RJ-45 counterparts on the copper side. This makes multimedia receptacle faceplates a little crowded and means that you get fewer terminations (lower density) in closets and equipment rooms than you can get with copper in the same space. The goal for the designers of the SFF connector was to create an optical-fiber connector with the same or lower crosssectional footprint as an RJ-45-style connector in order to increase the number of connections per area (higher density). The LC, the VF-45, and the MT-RJ SFF fiber-optic connectors were initially developed to support the increase in density of fiber connections. The LC Connectoris gaining greater use and is regarded by many optical-fiber professionals.

Guide To Choose The Best Fiber Optic Cable Suits Your Application

Fiber optic cable is favored for today’s high-speed data communications because it eliminates the problems of twisted-pair cable, such as near-end crosstalk (NEXT), electromagnetic interference (EMI), and security breaches. Fibre Optic Cable is the preferred option in the interconnecting links between floors or buildings, is the backbone of any structured cabling solution. While, making the right decisions when it comes to Data Network cabling is difficult as it can make a huge difference in the ability of your network to reliably support current and future requirements. There are many factors to consider and today I will guide you through the many options available and find the best one suits your application.

1. Multimode Fiber Cable Or Single-mode Fiber Cable

There are two basic types of fiber: mulitimode and single-mode. Both types consist of two basic components: the core and the cladding which traps the light in the core.

Multimode fiber cable

Multimode fiber, as the name suggests, permits the signal to travel in multiple modes, or pathways, along the inside of the glass strand or core. It is available with fiber core diameters of 62.5 and a slightly smaller 50 microns. The problem with multimode fiber optics is that long cable runs in multiple paths may lead to signal distortion. This can result in incomplete and unclear data transmission.

Applications covering short distances can use multimode fiber optic network cable. Ideal uses for such kinds of cables are within data center connections. Multimode cables are economical choices for such applications. There are various performance levels within the multimode fiber optic cable such as OM3 cable for distances within 300 m, OM4 cable supports Gigabit Ethernet distances within 550m and 10G applications.

Single-mode fiber cable

Single-mode fiber cables offer a higher transmission rate. These cables contain a tiny core that measures about five to ten microns. These tiny cores have the capacity to eliminate distortion and produce the highest transmission speeds. Single-mode fiber generally has a core that is 8.3 microns in diameter. Singlemode fiber requires laser technology for sending and receiving data. Although a laser is used, light in a single-mode fiber also refracts off the fiber cladding. The presence of high intensity lasers helps transfer data across large distances. Singlemode has the ability to carry a signal for miles.

Single mode is used for long haul or extreme bandwidth applications, gives you a higher transmission rate and up to 50 times more distance than multimode, but it also costs more. The small core and its single lightwave virtually eliminate any distortion that could result from overlapping light pulses, providing the least signal attenuation and highest transmission speeds of any fiber cable type.

The best choice to choose multimode optical cable when the transmission distance is less than 2km. In the other sides, use single-mode optical cable when the transmission is more than 2km. Although the core sizes of multimode and singlemode fiber differ, after the cladding and another layer for durability are applied, both fiber types end up with an outer diameter of about 250 microns. This makes it both more robust and easier to work with.

2. Indoor Cable Or Outdoor Cable

The major difference between indoor and outdoor cables is water blocking. Any conduit is someday likely to get moisture in it. Outdoor cables are designed to protect the fibers from years of exposure to moisture.

Indoor Cables

Indoor cables are what we call “tight-buffered” cables, where the glass fiber has a primary coating and secondary buffer coatings that enlarge each fiber to 900 microns—about 1mm or 1/25-inch—to make the fiber easier to work with. Indoor cables are flexible, and tough, containing multiple Tight Buffered or Unit Cord fibers.

Types Of Indoor cables available

indoor cables

Simplex and Zip Cord: Simplex Fiber Optic Cables are one fiber, tight-buffered (coated with a 900 micron buffer over the primary buffer coating) with Kevlar (aramid fiber) strength members and jacketed for indoor use. The jacket is usually 3mm (1/8 in.) diameter. Zipcord is simply two of these joined with a thin web. It’s used mostly for patch cord and backplane applications, but zipcord can also be used for desktop connections. They are commonly used in patch cord and backplane applications. Additionally, they can be utilized for desktop connections. These cables only have one fiber and are generally used indoors.

Distribution cables: They contain several tight-buffered fibers bundled under the same jacket with Kevlar strength members and sometimes fiberglass rod reinforcement to stiffen the cable and prevent kinking. These cables are small in size, and used for short, dry conduit runs, riser and plenum applications. The fibers are double buffered and can be directly terminated, but because their fibers are not individually reinforced, these cables need to be broken out with a “breakout box” or terminated inside a patch panel or junction box. The distribution cable is smaller and used in dry and short conduit runs, plenum and riser applications, is the most popular cable for indoor use.

Breakout cables: They are made of several simplex cables bundled together inside a common jacket for convenience in pulling and ruggedness. This is a strong, rugged design, but is larger and more expensive than the distribution cables. It is suitable for conduit runs, riser and plenum applications, is ideal for industrial applications where ruggedness is important or in a location where only one or two pieces of equipment (such as local hubs) need to be connected.

Outdoor Cables

Optical fiber in outdoor applications requires more protection from water ingress, vermin, and other conditions encountered underground. Outdoor cables also need increased strength for greater pulling distances. Buyers should know the potential hazards that the cables will face, for example, if the cables will be exposed to chemicals or extreme temperatures.

Loose Tube cables: These cables are composed of several fibers together inside a small plastic tube, which are in turn wound around a central strength member and jacketed, providing a small, high fiber count cable. This type of cable is ideal for outside plant trunking applications, as it can be made with loose tubes filled with gel or water absorbent powder to prevent harm to the fibers from water. Since the fibers have only a thin buffer coating, they must be carefully handled and protected to prevent damage. It can be used in conduits, strung overhead or buried directly into the ground.

Ribbon Cable: This cable offers the highest packing density, since all the fibers are laid out in rows, typically of 12 fibers, and laid on top of each other. This way 144 fibers only has a cross section of about 1/4 inch or 6mm! Some cable designs use a “slotted core” with up to 6 of these 144 fiber ribbon assemblies for 864 fibers in one cable! Since it’s outside plant cable, it’s gel-filled for water blocking.

Armored Cable: Cable installed by direct burial in areas where rodents are a problem usually have metal armored between two jackets to prevent rodent penetration. This means the cable is conductive, so it must be grounded properly. You’d better choose armored fiber cable when use cable directly buried outdoor.

Aerial Cable: They can be lashed to a messenger or another cable (common in CATV) or have metal or aramid strength members to make them self supporting. Aerial cables are for outside installation on poles.

The table below summarizes the choices, applications and advantages of each.

Cable Type Application Advantages
Distribution Premises Small size for lots of fibers, inexpensive
Breakout Premises Rugged, easy to terminate, no hardware needed
Loose Tube Outside Plant Rugged, gel or dry water-blocking
Armored Outside Plant Prevents rodent damage
Ribbon Outside Plant Highest fiber count for small size

All cables share some common characteristics. For example, they all include various plastic coatings to protect the fiber, from the buffer coating on the fiber itself to the outside jacket. All also include some strength members for pulling the cable without harming the fibers. Outdoor fiber optic cable has moisture protection, either a gel filling or a dry powder or tape. Direct-buried cables may have a layer of metal armor to prevent damage from rodents. It is advisable that you should customize your cable to make it suitable to your application when the quantity of fiber optic cables is large and also for the cost-effective reasons. Knowing basic information about fiber optic cables make choosing the right one for the project a lot easier. It is always beneficial to konw more about fiber optic cables.

Something You Should Know Before Using Fiber Optic Jumper

Classifications of fiber optic jumper

Fiber optic jumper is a fiber optic cable with optical fiber connector plugs on both ends. Fiber optic jumpers are divided into the following three types by termination type basically: ST-ST, SC-SC, ST-SC.

According to the optical fiber type, optical fiber jumper mainly includes single-mode fiber and multimode fiber. The specifications of the jumper wire length are 0.5m, 1m, 2m, 3m, 5m, 10m and so on.

According to the fiber optic jumper connection structure, it can be divided into: FC fiber patch cable(Product Recommendation: 1m FC-FC Duplex 10G OM4 50/125 Multimode Fiber Patch Cable), LC fiber patch cable, MTRJ, MPO, MU, SMA, FDDI, E2000, DIN4, D4, etc.

According to the cable outer sheath material, fiber optic jumper can be divided into ordinary, ordinary flame retardancy, low smoke halogen, low smoke halogen flame retardant, etc.

According to the requirements of the level of building fire protection and for materials refractory, integrated wiring system should take corresponding measures. In an area where flammable and building shaft inside the cloth cable or fiber optic cable, flame retardant cable and optical cable should be adopted. In large-scale public places should be flame retardant, low smoke, low toxicity; Equipment between should use flame retardant wiring devices.

Applications for fiber optic jumper

Fiber optic jumper wire is used for patch cords from the device to the optical fiber link. It has a thicker layer in using in optical transceiver and the connection between the terminal box.

1. Optical fiber communication system

2. Fiber-optic broadband access network

3. Optical fiber for CATV

4. Local Area Network(LAN)

5. Fiber optic instrument

6. OFS(optical fiber sensor)

7. Optical fiber data transmission system

8. Testing equipment

What should we pay attention to when using fiber optic jumper?

When using fiber optic jumper, you should make sure that wire light wavelength of transceiver module at the ends of the fiber optic jumper must be identical, that is to say, the ends of the optical fiber must be the same wavelengths as light module. A simple way to distinguish is the color of the optic module.

In general cases, short wave optical module uses multimode optical fiber with orange, and long wave module uses single-mode optical fiber with yellow. To ensure the accuracy of the data transmission, please do not bend the optical fiber jumper too excessively, which will increase the light attenuation in the transmission process. After using the fiber optic jumper, you must guard the fiber optic connector by protective material, dust and oil pollution which can damage the coupling of optical fiber.

Furthermore, to ensure the quality of the joint, you must pay attention to the radius of curvature. Each fiber optic jumper should be in accordance with ISO/IEC and ANSI/TIA/EIA for durability, moisture, coupling stress, optical fiber tensile force and the moisture, temperature extremes, insertion force and cable tension stress, impact and vibration and other bad environment to meet the requirements.

Effectively Cable Management Cable is Almost Like an Art Form

As the modern workplace and family become more complicated and the use of more technology, so a lot of cables, infiltrate into our daily life is in proportion. In order to prevent becoming lost in the tangle, effective cable management is essential. Fortunately, there is a wide range of products and cable accessories in the market, this task is a little easier than ever.

Cable management kits

There are so many different accessories on the market, it can be difficult to know what to buy. For this reason, the cable management suite is a great choice, because they have a convened a series of items need to clean up and organize effective cable.

This kits come in many different shapes and forms, but all contain a variety of tools for effective cable management. Many contain a combination of cable wraps, ties and clamps. Others might contain cable trunking and accessories for fireproofing your cables and increasing airflow around them.

FiberStore products’ kits are perfect for added safety and fire prevention, and provides a fireproof seal for cables. The FiberStore cable joint kit meanwhile provides an all in one cable jointing solution utilising PVC and Polyurethane resin.

The importance of cale management

Cable management is particularly important in offices and other workplaces which make extensive use of computers and other electric equipment. Without a carefully thought out cabling strategy, server rooms and data centres could end up looking like spaghetti junction, with a tangled maze of cabling scattered haphazardly across floors and walls.

A disorganised cable management strategy is not only a logistical and aesthetic nightmare, it is also a health and safety risk.

Firstly, individuals working in close proximity to the cables might trip over them, endangering both the employee and the equipment.

Secondly, and most importantly, poorly coordinated cables present a significant fire risk. Many fires start as a result of electrical failure, and in the event of a fire, cables that are not protected may a result of electrical failure, and in the event of a fire, cables that are not protected may perish in the fire, exposing live wires and presenting a further electrical hazard to evacuating personnel.

To protect against such dangers, all kinds of cable management kits and other products with flame retardant qualities are available. The Kopex Flexible Conduit provides a flame retardant cabling solution, featuring a galvanised steel core and a PVC cover, and is both flexible and versatile.

Trunking pillows, such as the Newlec Fire Protection Pillow, can also be used to reduce the risk of fire. These are made of fire resistant compounds and are utilised to plug holes bored in walls and ceilings for the purpose of electrical cabling. This is vital, because in the event of a fire flames may quickly spread from room to room via any unsealed holes.

Effective and efficient cable management

Effectively management cable is almost like an art form, if do well can save time and money in the long run, and protect your equipment and your workers unnecessary risk.
