Central Tube Armored Cable GYXTW

GYXTW Fiber cable, from 2 ~ 12 cores, SM, OM2, OM3 aviable.

General Details

The fiber optic cable consists of a bundle of glass threads (fiber core), each of which is capable of transmitting messages modulated onto light waves. featured with the following advantages compared with tranditional copper cable: Fiber optic cables have a much greater bandwidth to carry data than copper cables. Fiber optic cables are less susceptible than copper cables to interference. Fiber optic cables are much thinner and lighter than copper wires.

The 250um fiber cores are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant Gel. The tube is wrapped with a layer of PSP longitudinally. 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. The cable is completed with a polyethylene (PE) sheath.

Installation method
Aerial, Duct and direct burial.
