KEXINT GCYFY Mini Central Tube Type Air-blown Fiber Optical Cable For Pipes
 
Large core number air blowing cable GYFY cable structure is the phi 250 mu m optical fibers are jacketed high modulus material made of loose tube, the loose casing pipe is filled with waterproof compound, loose tube around the center of the strengthen core twist synthetic compact round cable core, the cable core gap mid to moisture-proof waterproof yarn, then extruding PE sheathed cable.

Feature:·Small outside diameter, light weight, easy to lay.
 ·Adopt semi dry structure, construction is clean and tidy.
 ·Loose tube material itself has a good water resistance and high strength.
 ·special tube filling compound ensure a critical protection of fiber.
 ·Adopt the following measures to ensure the waterproof performance of the optical cable.
 ·Loose tube filled with special waterproof compound.
 ·Using dry type of water blocking material, the whole section of water resistance, to prevent the optical cable vertical
 seepage.

Application:· Using microtubule resources, especially for the backbone network, access network and fiber to the home.
 · Cabling costs are low and suitable for upgrading the old city and building network.
