GJYXFFCH cable takes the colored fiber (single mode or multi-mode fiber) as the signal transmission unit, and the two sides of the cable are respectively placed with a non-metal reinforcement to form a square structure. At the same time, the high strength aramid yarn is used as the reinforcement to play a self-supporting overhead effect, and on this basis, a flame retardant polyolefin material is extruded to form a outer sheath.

·The outer diameter of the product  is small. Compared with the traditional self-supporting outdoor 8-figure cable,  the weight is lighter and the installation is more convenient ;

·It has high pressure resistance and  tensile, and can stand a  certain wind speed ；

·Specific V-shaped cable is  convenient for stripping and field installation ;

·The outer sheath is made of  flame retardant material, which can meet the requirements of flame retardant  grade and environmental performance of outdoor optical cable .

· Self-supporting cable can span within 50m in mountain or hilly areas ；
· It can meet the requirement of pole and line laying with a certain span,  and the distance is longer than that of ordinary self-supporting leather cable ；
· Has high cost performance, widely  used in FTTH home-entry .
