注：1、表中所有数值均作为参考，若数值有增改，怒不另行通知；

    2、光缆缆芯采用250μm的着色涂覆光纤；

3、表中光缆允许的拉伸力和压扁力为选用FRP和钢丝两种加强元件时，光缆分别允许的力值；

4、采用G.657光纤时，静态最小弯曲半径为15mm.

Note：1、All the values in the table,which are for reference only,are subject to change without

         notice;

  2、The cable core use the colored coading fiber of 250μm;

  3、The tensile and crush of the cable are accordance with the values in the table when

     the strength member of FRP and steel are used;

      4、The minimum bend radius(static)is 15mm when G.657 fiber is used.
