GYTZA Armored Flame Retardant Optical Fiber Cable Stranded Loose Tube Outdoor 2-6 core Fiber Optic
The stranded flame retardant optical fiber is housed in a loose tube made of a high modulus plastic and filled with a waterproof tube filling compound. The tube (and filler) is wound around a metal center strength member to form the cable core. Plastic coated aluminum strip (APL) is longitudinally wrapped and extruded into a flame-retardant sheath to form a cable.It is Suitable For outdoor and indoor use in networks for telecom, cable TV and/or broadcast.
The stranded flame retardant optical fiber is housed in a loose tube made of a high modulus plastic and filled with a waterproof tube filling compound. The tube (and filler) is wound around a metal center strength member to form the cable core. The cable core is armored with laminated aluminum tape. Then, an LSZH outer jacket is extruded.
