A new method of precise measurement ofopticalfiberattenuation.
一种新的精确测试光纤衰减方法的探讨。

The fiber undergone robust environmental testing that enables its stability against hydrogen-induced attenuation, to ensure long-term reliability of field installed opticalfiber cables.
The influences of length, dispersion index and attenuation index of transmission fiber and incident optical power on ber (bit error rate) and Q value of the system is analyzed.
