Fiber Cable (GYXTW)

Optic Series
D173/D174

Introduction PE Outer Sheath
PSP
The fibers are placed in a loose tube made of PBT. The tube Water blocking material
is filled with a water-resistant filling compound. The tube is Loose tube
wrapped with a layer of PSP longitudinally. Between the PSP Steel wire
and the loose tube water-blocking material is applied to keep Fiber
the cable compact and watertight. Two parallel steel wires Tube filling compound
are placed at the two sides of the steel tape. The cable is
completed with a PE sheath.
