如何查看华为交换机路由器光模块的收发光功率?
使用命令display transceiver verbose查看光模块的收发功率。gigabitethernet0/0/1版本不一样,显示信息有所差别,举例如下:
1、盒式交换机&框式交换机 V100R006C03&V100R006C05版本
RX Power(dBM)代表光模块接收功率,TXPower(dBM)代表光模块发送功率。

3、那么如何保证光模块的收发功率?
光模块的诊断信息中,可以查看当前发送和接收的光功率值,以及默认的最高和最低功率值。
如果接收功率低(RxPowerLow),说明本端接收到的信号过低,则可能出现端口不UP或者UP后报文收发有丢弃,此时请先排查传输距离是否过远,超出了该光模块的传输距离,再排查链路,如光模块、光纤是否有损坏,光纤单模多模是否用错,熔纤连接处质量是否可靠等,以及对端光模块发送功率是否过低。
如果接收功率高(RxPowerHigh),说明本端接收到的信号过高,可能原因是该光模块为长距光模块,而实际传输距离太短,导致信号未衰减,此时应在光模块上增加光衰,以对光模块进行保护。
如果发送功率低(TxPowerLow),说明该光模块发送信号不好,可能会导致对端接收功率低,而造成端口不UP或者UP后报文收发有丢弃,可能原因是光模块光口受污染,如灰尘积的太多等,此时请用棉签清洗光模块,然后再测试光口发光功率是否恢复正常。
如果发送功率高(TxPowerHigh),说明该光模块发送信号太强,可能会导致对端接收功率高,而造成对端光模块因接收功率持续过高而烧坏,可能原因是本端光模块故障,建议更换光模块。
因此,在端口插入光模块并对接成功后,要对发送或接收光功率方面的告警信息进行排查,避免因功率过低或者过高造成流量或者光模块不正常。
