·FTTH 室內(nèi)光纜 FTTH Indoor Cable
·產(chǎn)品描述 Description
FTTH室內(nèi)光纜是將光通信單元處于中心，兩側(cè)放置兩根平行非金屬加強(qiáng)元件（FRP），最後，擠制黑色或彩色低煙無鹵護(hù)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.
