GYFTY33 Anti Rodent Optical Cable

The GYFTY33 fiber optic cable design in double steel armored tape which stronger Mechanical performance on pulling tension and crush resistance . Double armored double jacket design also with excellent anti rodent protection .Double water block yarn and water swealable material tape around cable core providing good performance on water proof.

It is armored with galvanized steel wire, and double jacketed. The fiber optic quantity is from 2 to 144, soft tissue, user-friendly design, and the fiber type can be single-mode or multi-mode according to customers’ requirement. Cable construction can be single steel wire armored or double steel wire armored for different tensile load.

 

Application: This tough rugged cable is ideal for all external environments including direct burial, tunnels and heavy duty ducts.Water Resistant, Rodent Resistant, Flame Retardant.

Structure Design:

Main Features:
●Excellent mechanical and temperature performance guaranteed by the accurate excess fiber length
●Critical protection to fibers,
●Excellent crush resistance and flexibility
●The following measures are taken to ensure the water blocking performance of the cable:
– Single steel wire used as the central strength member
– Special water-blocking filling compound in the loose tube.
PSP moisture barrier
– water-blocking yarn and water swellable  material tape  double water proof
