标题: FTTH 室內光缆
·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.


·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;

        · 兩根平行FRP使光纜具有良好的抗壓性能，保護光纖；
        · Two parallel FRP strength members ensure good performance of crush resistance to protect the
          fiber;

        · 光纜結構簡單，重量輕，實用性強；
        · Simple structure, light weight and high practicability;

        · 獨特的凹槽設計，易剝離，方便接續，簡化安裝和維護；
        · Novel flute design, easily strip and splice, simplify the installation and maintenance;

        · 低煙無鹵阻燃護套，環保。
        · Low smoke, zero halogen and flame retardant sheath.
