GJFJHV branch optical cable structure is to place aramid reinforcing elements on the surface of tightly packed optical fibers and then extrude the sheath into sub-units. The sub-units are twisted with the non-metallic reinforcing FRP (and possible cushion) to form a circular shape. A dry water-blocking belt is wrapped between the core and the sheath, and finally the PVC (or LSZH) sheath is extruded into a cable.
♦ Layer-twisted cable structure, non-metallic center reinforcement core to enable the cable to withstand greater tension
♦ External protective materials are corrosion-resistant, waterproof, ultraviolet-resistant, flame-retardant, environmentally friendly and so on.
♦ Aramid fiber reinforcement components, so that optical cables have excellent tensile properties
Comply with Standard YD/T 1258.2-2003, ICEA-596, GR-409, IEC794, etc.
Meet the requirements of UL approval for OFNR and OFNP.
