·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），在外側再附加一根鋼絲加強元件，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. A steel wire as the additional strength member is also applied. Then the cable is completed with a black or color LSZH sheath.


·产品特点 Characteristics


        · 特種耐彎光纖，提供更大的帶寬，增強網絡傳輸特性；
        · Special low-bend-sensitivity fiber provides high bandwidth and excellent communication
          transmission property;
