接入网用蝶形引入室内光缆（GJFXH）
Bow-type drop cable
产品描述Description
GJFXH是将光通信单元处于中心，两侧放置两根平行非金属加强元件（FRP），最后，挤制黑色或彩色低烟无卤护套成缆。
The optical fiber unit is positioned in the centre.Two parallel Fiber Reinforced Plastics (FRP) are placed at the two sides.Then, the cable is completed with a black or color LSZH sheath.
