Several Common Bulk Fiber Cables

With the creation of modern technology, many new networks will choose to use bulk fiber cable instead of traditional copper based cables to increase the capability and speed of the network.Many different types of fiber optic cables in our life. They are generally used in different places. Under different conditions to select the appropriate cable.From Fiberstore, they inculding the Indoor Cables, Outdoor Cables, FTTH Cables, Armored Cables, LSZH Cables and some special cables. They are various at Aerial Cables, Building Cables, Direct buried cables, Duct Cables, Underwater/Submarine Cable. Some of our optical fiber comes with steel tube and steel wire armoring, suitable for sea, lake and river applications. Customers have the flexibility to choose a cable plant to best fit their needs. Only optical fiber that meets or exceeds industry standards is used to ensure quality products with best-in-class performance.So many cable in it, but do you know which cable you need.Tell you some info about LSZH cables,Ribbon fiber cable,Indoor Outdoor Cable.I think it can help you choose the nice cable.

What is Low Smoke Zero Halogen (LSZH) ?
Low Smoke Zero Halogen (LSZH) is a type if cable jacketing made of polypropylene that gives off limited smoke and no halogens when come across fire or strong heat. LSZH cable jacketing consists of thermoplastic or thermoset compounds that produce limited smoke and no halogen when come across high sources of heat, e. grams. flare.Low Smoke Zero Halogen cable can be called LSF (low smoke and fume), LSHF (low smoke halogen free), and LS0H (low smoke zero halogen).

Why to used the LSZH Cables ?
Low smoke zero halogen cable reduces the amount of toxic and corrosive gas emitted during combustion. This type of material is typically used in badly ventilated areas such as planes or railroad cars. Low smoke zero halogen is becoming very popular and, in some cases, a requirement where the protection of men and women and equipment from toxic and corrosive gas is very important.

They don’t produce a dangerous gas/acid combination in case of fire. LSZH patch cords are for utilization in patching environments with poor air circulation where personnel and equipment may be exposed to corrosive fumes and toxins during combustion. The cable jacket for these wires is designed to minimize the release of halogen fumes and toxicants into the air, reducing the potential of hazardous contact in occupied spaces. LSZH cables are mainly used in The european countries.

What is Ribbon Fiber Cable ?
Ribbon fiber optic cable is preferred where high fiber counts and small diameter cables are needed. This cable has the highest packing density, since all the fibers are laid out in rows in ribbons, typically of 12 fibers, and the ribbons are laid on top of each other. Not only is this the smallest cable for the most number of fibers, it’s usually the lowest cost. Typically 144 fibers in ribbons only has a cross section of about 1/4 inch or 6 mm and the jacket is only 13 mm or 1/2 inch diameter! 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 or dry water-blocked. These cables are common in LAN backbones and data centers.

Where can used the Ribbon Cables?
Ribbon cables are usually seen for internal peripherals in computers, such as hard drives, CD drives and floppy drives. On some older computer systems (such as the BBC Micro and Apple II series) they were used for external connections as well. Unfortunately the ribbon-like shape interferes with computer cooling by disrupting airflow within the case and also makes the cables awkward to handle, especially when there are a lot of them; round cables have almost entirely replaced ribbon cables for external connections and are increasingly being used internally as well.

What is Indoor Outdoor Fiber Optic Cable?
Indoor Outdoor Fiber Optic Cable
is designed to meet both the stringent environmental requirements typical of outside plant cable AND the flammability requirements of premise applications. Ideal for applications that span indoor and outdoor environments. By eliminating the need for outside to inside cross-connection, the entire system reliability is improved and with lower overall installation costs.

Ideal for applications that span indoor and outdoor environments, Indoor/outdoor cable can eliminate the need for building entryway splice points, saving both time and money. Outdoor/Indoor cables combine the flame resistance and safety features of an indoor riser or plenum cable with the durability that is critical for OSP use. The result is a unique, dual-purpose cable that can save time and money by allowing OSP applications to flow seamlessly indoors, using a single cable and no splices.

Note:Customers have the flexibility to choose a cable plant to best fit their needs.

Benefits From LSZH Jacked Cables

If protection of equipment or people is a design requirement, consider low-smoke zero-halogen (LSZH) jacketed cables. They emit fewer toxic fumes than standard PVC-based cable jackets. Typically, LSZH cables is used in confined spaces such as mining operations where ventilation is of concern.

What is the difference between LSZH cable and common cables?

The function and technique parameter of LSZH fiber optic cable is just like common fiber optic cables, and inner structure is also similar, the basic difference is the jackets. LSZH fiber optic jackets is more fire-resistant compared with common PVC jacketed cables, even when they are caught in fire, the burned LSZH cables provide low smoke and no halogen substances, this feature is not only environment protective but the low smoke when it got burned is also important to people and facilities in the fired place.

LSZH jacket is made up of some very special materials which are non-halogenated and flame retardant. LSZH cable jacketing is composed of thermoplastic or thermoset compounds that emit limited smoke and no halogen when exposed to high sources of heat. LSZH cable reduces the amount of harmful toxic and corrosive gas emitted during combustion. This type of material is typically used in poorly ventilated areas such as aircraft or rail cars. LSZH jackets are also safer than Plenum-rated cable jackets which have low flammability but still release toxic and caustic fumes when they are burned.

Low smoke zero halogen is becoming very popular and, in some cases, a requirement where the protection of people and equipment from toxic and corrosive gas is critical. This type of cable is ever involved in a fire very little smoke is produced making this cable an excellent choice for confined places such as ships, submarines, aircraft, high-end server rooms and network centers.

Every coin has two sides. Since LSZH cables have so many benefits listed above, what are the Cons of the cable?

1. LSZH is more susceptible to jacket cracking. Special lubricants have been made to minimize damage during installation.

2. LSZH jacket has a high filler content, around 50% to provide the required flame and smoke performance. This results in a lower mechanical, chemical resistance, water absorption and electrical properties then non LSZH compounds.

3. The current generation of LSZH cables has not yet established a proven history of long time performance.

The LSZH cables are available with 1, 2, 12, 24 fibers, and variable sub-cable dimensions that support specific termination and routing requirements. They are suitable for halogen free and many international installations. LSZH cable contains no flooding gel and is OFNR Riser rated, is perfect for installation in conduits between buildings and run directly thru risers to a convenient network or dome fiber optic splice closure without a separate point of splice at building entrance.

There are also LSZH fiber optic patch cords available. Both LSZH fiber optic cables and LSZH fiber optic patch cords are required for the Rosh compliant cable assemblies, but Rosh standard is more strict besides it require the cables to be LSZH type. LSZH fiber optic patch cable are used widely used in the places where expensive equipment would be damaged if exposed to corrosive gases, and they are also used in crowded areas like commercial centers and sports centers.
