The Difference Between Loose Tube Fiber and Tight Buffer Fiber

Tight-buffered cables oftenn are used for intra-building, risers, general building and plenum applications. Tight buffer fiber contains a thick coating of a plastic-type material which is applied directly to the outside of each individual fiber. Loose tube fiber optic cable is typically used for outside-plant installation in aerial, duct and direct-buried applications. Loose tube fiber contains multiple strands of fiber in a single jacket. Since the fibers are “loose” inside the jacket, outside forces are less likely to reach the fibers. This makes it the more durable option of the two.

Loose Tube Cable

Loose-tube fiber generally consists of 12 strand of fiber, but can range anywher as low as 6, all the way up to 244 strands. Loose tube cables can be either dielectric or optionally armored. The modular buffer-tube design permits easy drop-off groups of fibers at intermediate points, without interfering with other protected buffer tubes being routed to other locations. The loose tube design also helps in the identification and administration of fibers in the system.

In a loose tube cable design, color-coded plastic buffer tubes house and protect optical fibers. An optional gel filling compound impedes water penetration. Excess fiber length (relative to buffer tube length) insulates fibers from stresses of installation and environmental loading. Buffer tubes are stranded around a dielectric or steel central member, which serves as an anti-buckling element.

The cable core, typically uses aramid yarn, as the primary tensile strength member. The outer polyethylene jacket is extruded over the core. If armoring is required, a corrugated steel tape is formed around a single jacketed cable with an additional jacket extruded over the armor.

Tight-Buffered Cable

Single fiber tight buffered cables are used as pigtails, optical patch cord or fiber jumpers to terminate loose tube cables directly into opto-electronic transmitters, receivers and other active and passive components. Multi fiber tight buffered cables also are available and are used primarily for alternative routing and handling flexibility and ease within buildings. With tight buffered cable designs, the buffering material is in direct contact with the fiber. This design is suited for “jumper cables” which connect outside plant cables to terminal equipment, and also for linking various devices in a premises network.

The tight-buffered design provides a rugged cable structure to protect individual fibers during handling, routing and connectorization. Yarn strength members keep the tensile load away from the fiber.

As with loose-tube cables, optical specifications for tight-buffered cables also should include the maximum performance of all fibers over the operating temperature range and life of the cable. Averages should not be acceptable.

Some Other Fiber Optic Patch Cord

Armored fiber patch cords

Armored fiber patch cords (armored multi fiber cable) retain all the features of standard optical patch cord, but they are much stronger. The armored fiber patch cords will not get damage even it is stepped by an adult, and they are anti-rodents, when use such armored fiber patch cord, people do not need to worry that the rodent animals like the rats may bite the cables and make them broken. Although armored fiber cables are strong, they are actually as flexible as standard fiber optic patch cord; they can be bended randomly without being broken.

Armored fiber patch cord can be made similar outer diameter with the standard fiber patch cords, this make them space saving. What is more, they can be with different jacket colors and jacket types such as OFNR etc. and the armored fiber patch cords are actually light weight, the armored fiber patch cords can be with SC, ST, FC, LC, MU, SC/APC, ST/APC, FC/APC, LC/APC etc types of terminations.

The armored fiber optic patch cord has features as common type fiber optic patch cables but more robust designed to deploy in FTTH projects inside the buildings. The armored fiber optic patch cord use stainless steel armor inside the jacket to make the fiber patch cord resistant of high tension and pressure. It can resist the weight of an adult person and it is not easy to break when is bent or dragged. The armored fiber optic patch cord is flexible with high damage resistant by improper twist and also resistance of pressure and rodent bites.

MPO Fiber Patch Cord

MPO patch cord (Ribbon fan out Fiber patchcord, Ribbon mliti cable fan out) use MTP and MPO multi fiber type connectors, each one of the connector are used with ribbon type fiber optic cables which contain multi fiber in one single jacket, so that MPO Fiber Patch Cord greatly save space and are very convenient to use.

Bundle fan out patch cord 

Bundle fan out patch cord (Multi cable fan out) are enormously valuable in speeding up the installation process, by eliminating the need for unnecessary splicing or terminations in the field.

Bundle fan out patch cord assemblies can be with various structures and connectors options. Bundle fan out patch cord assemblies are available in various fiber counts, with distribution cable or outside plant cable. Outside plant cable assemblies utilize end-blocking kits for water protection and fan out tubing for fiber ruggedizing, Distribution is 900un tight buffered and typically not ruggedized, depending on the application. While Bundle fan out patch cord assemblies are most often pigtail, optical fiber jumpers are also available and provide numerous installation advantages. 

Bundle fan out patch cord assemblies are a custom design product; cable length, jacket types and connectors are with many options. To easily identify the multiple fiber cables, 0.9mm cable itself are made with different colors, if 2mm or 3mm cable it will be put number label to identify. Pulling eyes are also available with the cable; pulling eye is small devices, which can be fastened to the cable and easily, pull it through duct or small space place. Long fiber optic cable assemblies are usually packed by plastic or wooden reels to protect it from damage.

Construction

optical fiber jumper is constructed from a core with a high refractive index, surrounded by a coating with a low refractive index that is surrounded by a protective jacket. Transparency of the core permits transmission of optic signals with little loss over great distances. The coating’s low refractive index reflects light back into the core, minimizing signal loss. The protective jacket minimizes physical damage to the core and coating.

Size

Ordinary cables measure 125µm in diameter (a strand of human hair is about 100µm). The inner diameter measures 9µm for single-mode cables, and 50/62.69µm for multi-mode cables.

The development of “reduced bend radius” fiber in the mid-2000s, enabled a trend towards smaller cables. Each unit of diameter reduction in a round cable, produces a disproportionate corresponding reduction in the space the cable occupies.

Classification

Patch cords are classified by transmission medium (long or short distance), by connector construction and by construction of the connector’s inserted core cover.

Transmission medium

Single-mode fiber is generally yellow, with a blue connector, and a longer transmission distance. Multi-mode fiber is generally orange or grey, with a cream or black connector, and a shorter 
transmission distance.

Connector construction

Connector design standards include FC, SC, ST, LC, MTRJ, MPO, MU, SMA, FDDI, E2000, DIN4, and D4. Cables are classified by the connectors on either end of the cable; some of the most common cable configurations include FC-FC, FC-SC, FC-LC, FC-ST, SC-SC, and SC-ST.

Inserted core cover

The connector’s inserted core cover conforms to APC, UPC, or PC configuration. A UPC inserted core cover is flat and is used in SARFT and early CATV. An APC connector’s inserted core cover is 
oblique (about 30 °, ±5 °).

Applications

Patch cables are used for connections to CATV (Cable Television), telecommunication networks, computer fiber networks and fiber test equipment. Applications include communication rooms, FTTH (Fiber to The Home), LAN (Local Area Network), FOS (fiber optic sensor), Fiber Optic Communication System, Optical fiber connected and transmitted equipment, Defense combat readiness, etc.

Optical Patch Cord for Data Center Applications

Fiber patch cable or optical patch cord is an fiber cable that has fiber connectors on one or both ends. General use of these cable assemblies includes the interconnection of fiber cable systems and optics-to-electronic equipment. If the fiber optic connectors are attached to only one end of a cable, it is known as a pigtail. If connectors are attached to both ends, it is known as a jumper or patch cord.

Singlemode and multimode

Single mode fiber patch cables uses 9/125um glass fiber, Multimode fiber patch cord uses 50/125um or 62.5/125um glass fiber. Single mode and multimode refer to the fiber cable types. Single mode Fiber Patch Cord is used in long distance data transmission. Multimode Fiber Patch Cord is use in short distance transmission. Typical single mode Fiber Patch Cord used yellow fiber cable; Typically multi mode Fiber Patch Cord used orange fiber cable.

A Simple Introduction To Fiber Optic Patch Cable

optical patch cord is a cable that connects devices to allow information to pass between them. Patch cords are a common way of setting up wired connections between devices, such as connecting a television to a digital cable box using coaxial cable. These cords are used for any type of signal transference, such as in a television, radio or computer network. A optical fiber jumper is a special kind of cable that uses light to transfer signals at extremely high speeds with very little degradation. As a result of these properties, a fiber optic patch cord is typically a reliable way to transfer information.

Most modern homes are full of patch cords, as they connect stereo components, televisions, video game consoles and computers to one another. The ‘cable’ for cable television is a specialized type of patch cord that goes from the cable company’s box to the inside of a home. Network cable between a modem and a router, coaxial connections between a television and a digital video disk player and even the cable that connects an music player to a computer are all patch cords.

These cords come in a lot of different shapes, sizes and lengths. They have specialized connectors (such as ST-LC fiber patch cable, SC to LC patch cable) that allow a single cord to do a single job. Even though the ends look so different, there are really only a handful of different types of cords used as patch cables.

In between the varied ends, coaxial cable is the most common type of connection found in entertainment systems, and Ethernet cable is common in networked devices. Single-wire cords are less 
common, but are used in some kinds of scientific and audio equipment. Lastly, fiber optic patch cord can actually do everything the others can do faster and with less signal loss, but it is more expensive and has some problems not found in other materials.

Fiber optic cords use a plastic or glass core, surrounded by reflective material and protective cladding, to send pulses of light. These cables transfer information at very high speeds, since they use actual light rather than electrical pulses to move the information. In addition, light is not disrupted by electromagnetic noise the way electrical pulses are, allowing the signal to stay nearly pure.

Since fiber optic patch cord is often considered superior to other types in speed and clarity, it seems like it would be everywhere, but it does have some problems. The design of a fiber optic patch cord is very specific. Small variations or problems in manufacture that traditional cables wouldn’t even notice will totally stop transmission. A fiber optic patch cord may also end up cracked when it is bent at a sharp angle; this will also stop any transmission. After a fiber optic cord is made, it is also very hard to change its length, as opposed to electrical cables which can be connected or cut very easily.

Fiber Optic Patch Cables With Different Fiber Optic Connectors

Fiber optic patch cable can be also classfied by the types of fiber optic connector. For example, LC fiber optic patch cable is named as it is with LC connector. Similarly, there are SC, ST, FC, MT-RJ, E2000, MU and MPO/MTP fiber optic patch cables. What’s more, there are PC, UPC, APC type fiber patch cords, which are differentiated from the polish of fiber connectors.

LC Fiber Optic Patch Cable

LC fiber optic patch cable (LC fiber cable)is terminated with LC connector. LC is the short form of Lucent Connector. LC connector is a push and latch structure, with plastic housing and accurate 1.25mm ceramic ferrule. LC type is a popular kind of small form fiber optic patch cable which reduce the space and it is widely used for densely installation. The LC fiber patch cables use a 1.25 mm ferrule, half the size of the ST patch cable. It has good performance and is highly favored for single mode patch cord. LC fiber patch cables comply with IEC, Telcordia, ANSI/EIA/TIA .The connector of LC patch cable is used on 1.6mm/2.0mm as well as 3.0mm cable. There are LC/PC (for multimode), LC/UPC and LC/APC (for single mode) patch cables.

SC Fiber Optic Patch Cable

SC fiber optic patch cable is terminated with SC connector. The SC connector was invented by the Japanese company NTT. SC stands for Subscriber Connector or Square Connector or Standard Connector. It is extremely common in datacom and telecom fiber optic market. It has a push and pull type and can be used for 1000 mating cycles. SC fiber optic patch cable is with a locking tab on the cable termination and provides for accurate alignment through their ceramic ferrules. It has an advantage in keyed duplexibility to support sending and receiving channels. SC fiber optic patch cable features low cost, simplicity as well as good durability. It is the most cheapest type, convenient to use and cost saving. SC fiber optic patch cable is widely used in fiber optic networks and can be with zirconia sleeve and plastic housing.

ST Fiber Optic Patch Cable

ST fiber optic patch cable (ST fiber cable)is terminated with ST connector. ST stands for Straight-Tip and features a Bayonet twist locking mechanism. ST connector has 2.5mm diameter ferrule as in SC connector. It was developed by AT&T and was very popular in the 1980s and 1990s. ST connector has bayonet-style housing and a long spring-loaded ferrule hold the fiber. It is available in both multimode and single mode versions. Horizontally mounted simplex and duplex adapters are available with metal or plastic housing, with a choice of phosphor bronze or zirconia split sleeve. Although there are plastic housing ST connectors, more and more people tend to use metal housing ST. ST fiber optic patch cable has straight tip type terminations and is easy to insert and remove. If you experience high light loss, try to reconnect it. It is rated for 500 mating cycles. ST fiber optic patch cable is one of the older generations, but it is still widely used for multimode networks, including LANs for buildings and campuses.

FC Fiber Optic Patch Cable

FC fiber optic patch cable is terminated with FC connector, a screw type connection. FC stands for Fixed Connector. Same as SC connector, FC is also invented by NTT. FC is with metal housing, screw structure. FC connector ferrule and sleeves used in FC adaptor are both same as SC ones. FC fiber optic patch cable is available in both single mode and multimode versions. It is applied in high-vibration environment and can screw on firmly, but you need to have the key aligned in the slot properly before you tighten it.

MTRJ Fiber Optic Patch Cable

MTRJ fiber optic patch cable is terminated with MTRJ connector. MTRJ stands for Mechanical Transfer Registered Jack. MTRJ connector is developed from MT and RJ connectors. It is with plastic housing and plastic ferrule and features two-fiber connection, that is to say, two fiberglass connection within one MTRJ fiber optic connector. MTRJ connectors use molded MT ferrules originated by NTT. Each MTRJ connector houses two fibers (duplex) and the footprint resembles copper RJ45 Ethernet connector. It is half the size of a SC connector and contributes to the price drop per fiber port on fiber-to-the-desktop solutions. MTRJ connectors come in male (with two metal pins) and female (no pins). MTRJ fiber optic patch cable has female type and male type. The difference between them is that the male type is with two pins on each of the MTRJ connector. The MTRJ patch cable is commonly used for networking applications. Its size is slightly smaller than a standard phone jack and is easy to operate.

E2000 Fiber Optic Patch Cable

E2000 fiber optic patch cable is terminated with E2000 connector. E2000 connector has a spring-loaded shutter used to protect the ferrule from dust and scratches. With similar structure of SC connector, it is smaller. E2000 fiber optic patch cable is one of the latest style yet one of the most expensive optical patch cord.

MU Fiber Optic Patch Cable

MU fiber optic patch cable is terminated with MU connector. MU connector is also the invention of NTT. It is with plastic housing and a push pull structure. MU connector is also a small form-factor connector which features a 1.25mm diameter ferrule as in LC connector. MU connector has the same push-pull locking mechanism as SC connector. MU fiber optic connector is similar size of LC and sometimes named small-SC. MU connectors are used in advanced optical transmission, exchange, and subscriber systems or high speed data application. MU fiber optic patch cable is developed to replace SC in the future.

MPO/MTP Fiber Optic Patch Cable

MPO fiber optic patch cable is terminated with MPO connector. The MPO is an high-density multi-fiber connector built around precision molded MT ferrule. It is a push-pull connector compliant IEC 61754-7 and TIA/EIA 604-5A and offers low cost per termination for high density applications. It is usually used in ribbon fiber optic patch cables or ribbon fan out multi fiber assemblies. MPO has multi fiberglass core inside each single connector, that is to say, there are several fiberglass connections in each single MPO fiber optic patch cable, for example, 12 fiber, 24 fiber, 36 fiber, etc. MTP is upgrade version of MPO. MTP fiber optic patch cable allows high-density connections between network equipment in telecommunication rooms. It uses a push-pull latching mechanism for easy and intuitive insertion and removal.

MPO patch cord (Ribbon fan out Fiber patch cord, Ribbon mliti cable fan out) use MTP and MPO multi fiber type connectors, each one of the connector are used with ribbon type fiber optic cables which contain multi fiber in one single jacket, so that MPO Fiber Patch Cord greatly save space and are very convenient to use. Based on single ferrule MT technology, the MPO Fiber Patch Cord assemblies provide up to 72 fiber connections in a single point, reducing the physical space and labor requirement, while providing the same bandwidth capacity of a multi-fiber cable with individual fiber connector terminations per cable. Typical MPO fiber optic patch cable assemblies are MPO to 8 LC, MPO to 12 MTRJ, etc. MPO fiber optic patch cable is also available by single mode and multimode, PC and APC polish. FIBERSTORE MPO fiber patch cables are available in 12, 24, 36, 48, 72, 96 and 144 fiber versions, PC and APC finishes, and support both multimode and single mode applications.

Why Fiber Optic Patch Cables Are Helpful

In the modern era of technology, fiber optics has started to play an important role in data transfer and communication. The data transfer that happens in these cables are based upon the technology of optical networks. Light waves are encoded and modulated to send and receive data. And optical patch cord play an important role in completing the end-to-end connection of systems using this technology.

First of all, let us understand what makes the optical fiber communication important. The fiber optics make sure that certain desired properties of any communication are satisfied. And the quality that they maintain with respect to these properties makes using these network cables desirable.

Interestingly, the optical fiber jumper require being compatible with all these properties to keep up with the network quality. So the attributes desirable of the fiber cables are also good for the patches. Some of the important properties are listed below.

Rate of data transfer: Data of high volume can easily be transferred using the optic cables. In fact, with the mainline network cables, one can transfer terabytes of data every second as done in case of the worldwide Internet exchange data. The same can be said about the fiber optic patch cables. The bandwidth of these cables are extremely high.

Speed of communication: The physical communication happens over modulated waves of light. As a result, the speed of communication is extremely fast with the fiber optic networks. One can use these networks to access real time data across the globe. The patch cables are compatible with the speed and they can transfer data at the same speed as the main network cable.

Absence of attenuation: Attenuation of signal is a critical factor in most of the networks. However, for an optical network, this is practically absent. The data can traverse along the network with no amplifier installed in route. The patch cables also do not attenuate the data.

Accuracy of transferred data: The transfer of data takes place with a high degree of accuracy. The data suffers from practically no external hindrance. No signal coming form outside really changes anything about the data. As a reault, the data transfer preserves the accuracy of information exchange. The fiber optic patch cables maintain high levels of accuracy when it comes to data transfer.

Security factors: Fiber optic patch cables are as secure as the overall optical fiber network. They are extremely difficult to break into and hence the possibility of data leaking out of the network is practically minimal.

All of the above makes using fiber optic patch cables helpful when it comes to real life application. Make sure that you have got the right patch with the right length and aperture, and you are all set to enjoy the benefits of a secure and high speed communication.

ST Fiber Optic Patch Cord (ST Fiber Cable)

Description

The ST connectors used in our patch cords employ half-twist bayonet locking mechanism and high quality 2.5mm zirconia ferrules. They are fully compatible with existing ST type hardware.

In addition to basic testing, some mechanical and environmental tests per IEC or Telcordia are also performed periodically to guarantee the best quality. For standard patch cords, sampling check is performed on ferrule geometry to ensure high percentage of polished connectors meeting GR-326 requirements. For premium grade, ferrule geometry is tested on all patch cords to meet these GR-326 requirements.

Other than standard single mode and multimode fibers, OM2, and OM3 fibers are also available upon request. Flame retardant grade cable sheathing options are offered. Riser rated cable will be provided as standard. LSZH and Plenum can be provided upon request.

The Meaning of The Fiber Optic Patch Cord

Fiber is divided into two categories:

Single mode fiber: General optical fiber jumper in yellow, connector and protective sleeve in blue; transmission distance is longer.

Multimode fiber: General optical patch cord in orange, and some in gray, fittings and protection applied beige or black; transmission distance is shorter.

Fiber Optic Connector Type:

There are many types of fiber jumpers, according to connector shape can be divided into: FC, SC, ST, LC fiber cable, etc.; can be divided according to the type of ferrule: PC, UPC, APC, etc.; according to type can be divided into single mode optical fiber, 50 / 125 Multimode, 62.5/125 multimode, polarization, etc.; based on fiber diameter can be divided into: 900μm, 2mm, 3mm and so on.

Applications

Fiber access products are widely applied to: communications room, fiber to the home, local area networks, fiber optic sensors, fiber optic communication systems, fiber optic transmission equipment connected, defense readiness, etc.

Uses and Features:

A variety of high quality fiber optic patch cords and pigtails broadband for cable television, telecommunications networks, computer networks and optical fiber test equipment.

Fiber optic patch cords and pigtails fiber counts and physical structure according to customer special requirements. High return loss and low insertion loss. Using high precision ceramic ferrule. Precision ground and fully testing.

Optical Fiber Using Precautions:

Both ends of the optical fiber jumper wavelength transceiver module must be consistent, that must be the same at both ends of fiber optic wavelength optical module, a simple distinction is consistent with the color of the optical module. Under normal circumstances, short-wave optical module using multimode fiber (orange fiber), long wavelength single-mode fiber module (yellow fibers), in order to ensure data accuracy. Do not use excessive fiber in bending and circling, this will increase the attenuation of light in the transmission process.
