FTTH indoor Butterfly Cable
1. Descreption of FTTH indoor Butterfly Cable (GJXH/GJXFH/GJXFJH/GJXFDH)
FTTH indoor butterfly cable is the optical communication unit in the center. Two parallel reinforcements (FRP/KFRP/steel wire) are placed on both sides. Finally, black or color low smoke halogen-free flame retardant sheath cable is extruded.
Covered optical cables are mostly single-core and double-core structures, and can also be made into four-core structures. The cross-section is 8-shaped, and the reinforcement is located at the center of the two circles. Metal or non-metallic structures can be used. The optical fiber is located at the geometric center of the 8-shaped. . G.657 small bending radius optical fiber is used for the optical fiber in the sheathed optical cable, which can be laid with a bending radius of 20mm, which is suitable for entering the house in the building by means of pipes or bright lines.
2. Features
♦ Special bending-resistant optical fibers provide greater bandwidth and enhance network transmission characteristics.
♦ Two parallel FRP/KFRP or steel wires have good compressive properties and protect optical fibers.
♦ Optical cable has simple structure, light weight and strong practicability.
♦ Unique groove design, easy to peel off, easy to connect, simplify installation and maintenance.
♦ Low smoke halogen-free flame retardant sheath, environmental protection.
