What is flame retardant optical cable?
Flame-retardant optical cable uses flame-retardant polyethylene sheath material instead of the polyethylene sheath material of ordinary optical cables, so that the optical cable has flame-retardant properties, while improving structural size and transmission performance.
The machinery and environment are connected with ordinary optical cables.
The structure of the flame-retardant optical cable suitable for communication places with flame-retardant requirements is The single-mode or multi-mode optical fiber is inserted into a loose tube made of high-modulus plastic, and the tube is filled with a water-blocking compound.The center of the cable core is a phosphated steel wire or a steel wire rope extruded with polyethylene. The loose tube (or filled rope and signal wire) is twisted around the central strengthening core to form a compact and round cable core. The gap in the cable core is filled with water-blocking filler steel-polyethylene bonded inner sheath, and the blue flame-retardant PVC sheath is used to complete the cable.
