最好能详细解释一下,谢谢
最佳答案
你好!
1、操作实例,光纤线路没有中断:
OLM 1 OLM 2
LED = 点亮绿灯 系统 LED = 点亮绿灯
CH1 LED = 点亮黄灯 CH1 LED = 点亮黄灯
CH2 LED = 点亮黄灯 CH2 LED = 不亮
CH3 LED = 不亮 CH3 LED = 点亮黄灯
2、 错误实例,光纤线路1有中断
OLM 1 OLM 2
系统 LED = 点亮绿灯 系统 LED = 点亮绿灯
CH1 LED = 点亮黄灯 CH1 LED = 点亮黄灯
CH2 LED = 点亮红灯 CH2 LED = 点亮黄灯
CH3 LED = 点亮黄灯 CH3 LED = 点亮红灯
3、错误实例,光纤线路2有中断
OLM 1 OLM 2
系统 LED = 点亮绿灯 系统 LED = 点亮绿灯
CH1 LED = 点亮黄灯 CH1 LED = 点亮黄灯
CH2 LED = 点亮黄灯 CH2 LED = 点亮红灯
CH3 LED = 点亮红灯 CH3 LED = 点亮黄灯
不管信道LED是否点亮,冗余光纤环网中的所有光纤信道都被连续的监控。在信道LED没有点亮的情况下,该光纤信道中的消息是用来监测传送的长度。生产性的通信是通过LED点亮黄灯的那个信道进行的。
错误总是通过信道LED点亮红灯和警报 连接的形式发出通知信号的。推荐连接警报连接以确保OLM的可靠监测。
