厂家供应光纤到户蝶形皮线光缆GJXH-4B1 室内4芯单模通讯光缆
产品描述 Description
|
FTTH室內光纜是將光通信單元處于中心，兩側放置兩根平行非金屬加強元件（FRP），最後，擠制黑色或彩色低煙無鹵護套成纜。
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.
