Description:

 

The structure of GYTA cable is to insert 250 micron optical fibers into the loose sleeve made of high modulus materials and fill the loose sleeve with waterproof compounds. The core of the cable is a metal reinforced core. For some optical cables with core numbers, a layer of polyethylene (PE) should be extruded outside the metal reinforced core. Loose sleeve (and filling rope) around the center reinforcement core to form a compact and circular cable core, the gap in the cable core is filled with water-blocking filler. Polyethylene sheathed cables were extruded after plastic-coated aluminium strip (APL) was vertically wrapped.

 

Important notice:

 

Many domestic small factories use inferior or waste optical fibers to imitate A-grade optical fibers, non-woven fabrics as water-blocking tapes, waste electric-wires and rubber slippers smashed as raw materials for the outer sheath of cable. Those inferior cables will cause many problems such as short transmission distance, low bandwidth, intermittent signal and easy-to-crack and water seepage of the cable jacket, etc. For the recent years, there are many cases that many overseas customers who bought such inferior cables from China were frustrated to find that the cables can not be used after constructing. It’s not workable to return them to China as the Chinese government will levy high import duties on optical fiber cables. The customers cannot claim for any compensation and suffered huge losses.

 

Characteristics.

 

  Good mechanical and temperature performance

· High strength looes tube that is hydrolysis resistant

· Special tube filling compound ensure a critical protection of fiber

· Specially designed compact structure is good at preventing loose tubes from shrinking

· PE sheath protects cable from ultraviolet radiation

· The following measures are taken to ensure the cable watertight:

. Steel wire used as the central strength member

. Loose tube filling compound

. 100% cable core filling

. APL moisture barrier
