GYTS Optical Fiber Armored Cable
Description
GYTS optical fiber armored cable can provide different cable types whose fiber count ranges from 2 cores to 144 cores. It can be used in aerial building, pipeline and direct burial. The bandwidth of this optical fiber cable can achieve 1000Mhz.Km when it is at the wavelength of 1300nm.
Standard
The structure of GYTA optical fiber armored cable is to combine the fiber optic whose radius is 250μm inside the loose tube which is made of high modulus materials. And the loose tube is filled with a waterproof compound. In the center of the cable core is a metal-strengthening core which is sometimes sheathed with PE for cables with a particular fiber count. The loose tube (and fillers) strands the central strength member to form a compact and round cable core. The waterproof fillers fill up the gap inside the cable core. The double-sided PSP is longitudinally wrapped and sheathed with polyethylene to form up cable.
