摘要
以中国联通徐州分公司2.5G环4为例,着重分析两纤双向复用段保护环上线路故障造成的基站闪断,最后提出为减少基站闪断的概率应给光缆中断前的衰减留较大的富裕量,适当调低传输设备检测到误码的复用段倒换门限。
It fouces on the two fiber bi-directional multiplexing segment protection ring line fault caused by the the base station flash off, with the example of 2.5G Ring 4 of China Unicorn Xuzhou Branch. At last, It comes to the conclusion that we should improve the fiber attenuation, and reduce the error of the transmission equipment MSP switching threshold in order to reduce the probability of base station flash off.
