Flat Twin Fiber Cable GJFJBV


Flat Twin Fiber Cable GJFJBV

The flat twin cable uses 600μm or 900μm tight buffered fiber as the optical communication medium. The tight buffered fiber is wrapped with a layer of aramid yarn as a strength member. Such a unit is extruded with a layer as an inner sheath. The cable is completed with an outer sheath.(PVC, OFNP, or LSZH)

Product Features

Tight buffer fibers are easy to strip.

Tight buffer fibers have excellent flame-retardant performance.

Aramid yarn, as a strength member, makes the cable have excellent tensile strength. The flat structure ensures a compact arrangement of fibers.

The outer jacket material has many advantages, such as being anti-corrosive, anti-water, anti-ultraviolet radiation, flame-retardant, and harmless to the environment, among others.

All dielectric structures protect it from electromagnetic influence. Scientific design with serious processing art.

Suited for SM fiber and MM fiber (50um and 62.5um).

Packing And Mark

OYI cables are coiled on bakelite, wooden, or ironwood drums. During transportation, the right tools should be used to avoid damaging the package and to handle them with ease. Cables should be protected from moisture, kept away from high temperatures and fire sparks, protected from over-bending and crushing, and protected from mechanical stress and damage. It is not allowed to have two lengths of cable in one drum, and both ends should be sealed. The two ends should be packed inside the drum, and a reserve length of cable not less than 3 meters should be provided.

Micro Fiber Indoor Cable GJYPFV

The color of cable markings is white. The printing shall be carried out at intervals of 1 meter on the outer sheath of the cable. The legend for the outer sheath marking can be changed according to the user's requests.

Test report and certification provided.

      It is made from carbon steel with hot-dipped zinc surface processing, which can last a very long time without rusting for outdoor purposes. It is widely used with SS bands and SS buckles on poles to hold accessories for telecom installations. The CT8 bracket is a type of pole hardware used to fix distribution or drop lines on wooden, metal, or concrete poles. The material is carbon steel with a hot-dip zinc surface. The normal thickness is 4mm, but we can provide other thicknesses upon request. The CT8 bracket is an excellent choice for overhead telecommunication lines as it allows for multiple drop wire clamps and dead-ending in all directions. When you need to connect many drop accessories on one pole, this bracket can meet your requirements. The special design with multiple holes allows you to install all accessories in one bracket. We can attach this bracket to the pole using two stainless steel bands and buckles or bolts.
