Indoor Branch Optical Cable (GJPFJV)
GJPFBH-4B1.3
The GJPFJV optical cable structure is based on tight-buffered optical fiber as the basic unit. Multi-core bundled cables are used as sub-units and twisted into a round shape with FRP, and then extruded into a PVC (or LSZH) sheath to form a cable. Dry water-blocking materials are placed in the gaps between the cable core and the sheath.
Each sub-cable contains aramid reinforced fiber, which has good bending properties, does not contain grease, is hygienic and clean, and is easy to construct and connect.
The optical fiber in the sub-cable adopts a tight-buffered design and has independent reinforcement elements and sheaths to prevent damage caused by environmental and mechanical stress.
Low-smoke, low-halogen, flame-retardant sheaths are flame-retardant and self-extinguishing, suitable for indoor environments such as computer rooms, cable shafts, and wall wiring.
Low-smoke, halogen-free, flame-retardant polyolefin sheaths are UV-resistant, waterproof and mildew-proof, and resistant to environmental stress cracking, and there is no acid gas release, and it does not corrode computer room equipment. It is suitable for indoor and outdoor use or indoor environments that require a high flame retardant level (such as ceiling wiring, open wire wiring, etc.).
Product Application:
Indoor horizontal wiring, vertical wiring in buildings, LAN network.
The standard fiber core can be directly installed with connectors for connecting to equipment.
The tail cable used as the backbone network can be directly connected from the outdoors to the indoors, eliminating the junction box, isolating lightning, and improving system reliability.
