GYFXY Fiber Optic Cable
Description
The structure of the GYFXY unitube fiber optic cable combines fiber optic with a diameter of 250μm and fiber count ranging from 2 cores to 12 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 GYFXY fiber optic cable has a small diameter, light weight and is easy to lay. It also features an outstanding mechanical behavior, and its material features a high strength, excellent hydrolysis resistance. A special grease fills the tube, offering critical protection to the fiber optic. Two parallel steel wires ensure the tensile strength and the PE sheath features a great UV resistant performance.
