Unitube Mining Flame-retardant Optical Fiber Cable

We are producing and exporting of Unitube Mining Flame-Retardant Optical Fiber Cable to our consumers. The fibers 250um are posited in a loose tube made of high modulus plastic.the tubes are filled with a water-resistant filling compound.the tube is wrapped with a layer of PSP ,between the PSP and the loose tube water-blocking material is applied to keep the cable compact and watertight.two parallel steel wires are placed at the two sides of the steel tape.at last the cable is completed with a flame-retardant sheath.
Characteristics:
1.having excellent mechanical and temperature performance
2.the material of loose tube (PBT)has good hydrolysis resistant and high strength
3.Special tube filling compound ensure a critical protection of fiber
4.Special sheath material ensures excellent flame-retardant performance
5.PSP enhancing moisture-proof of cable
6.Two parallel steel wires ensure tensile strength of the cable
7.Small diameter,light weight ,makes it easy to install
8.Long delivery length
Standards: comply with standard Q62170406-MG001-2011 as well as MT386-2011 and pass MA certification
