Central tube Non-armored Cable (GYXY)

GYXY Fiber cable, non armored, 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 traditional 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 filling gel. Over the tube, water-blocking material is applied to keep the cable watertight. Two parallel steel wires are placed at the two sides. The cable is completed with a polyethylene (PE) sheath.

Installation method
Aerial, Duct and direct burial.
