GYXTW Fiber Optic Cable
Description
The structure of GYXTW unitube fiber optic cable combines fiber optic with a diameter of 250μm and fiber count ranging from 2 cores to 30 cores inside a loose tube made of high modulus materials. The loose tube is filled with a waterproof compound, and its exterior is also waterproof treated to prevent water penetration into the fiber optic cable. There is a parallel FRP on each side, which is sheathed with PVC to form up cables. The design of the loose tube is beneficial to the lengthy problems for precise fiber optic control. The attenuation of this fiber optic cable is 1.0dB and the bandwidth of it is 1000MHz.km while it is transmitting at the wavelength of 1300nm. It can be applied in self-supporting aerial laying.

Features
The double-sided PSP improves the moisture resistance of the GYXTW fiber optic cable, and two parallel steel wires ensure the tensile strength. It features a small diameter, light weight and it is easy to lay. It features a long length and outstanding mechanical behavior, hydrolysis resistance and high strength. A special grease fills the tube to offer critical protection. It also features a great compressive resistance and softness.
