GYTA53 Optical Fiber Cables

Description : 

The structure of this kind of cables is like that : a metal strength is put in the center of cable, several loose tubes (or partially fillers) are stranded outside of the central strength member and the gaps between loose tubes are filled with water-proof filling compound. The outside of the cable is overlapped with aluminum tape, and a PE inner sheath is extruded outside, then a corrugated plastics-coated steel tape is applied outside, and another PE sheath is extruded outside finally. For cables with large fiber count, usually and additional layer of PE sheath is extruded outside the central strength member. The loose tube is extruded from materials with good temperature performance and several single-mode or multi-mode fibers with proper excess length are put in the tube which is filled with water-proof filling jelly for fiber protection.
