配置波长

您可以为 SPF+ 光学器件配置光纤传输波长值。此配置使您能够将激光波长和频率调整为最多两个小数位数(以纳米级为单位)。

当 SPF+ 光学器件插入接口时,要配置和查看光纤传输波长,请执行以下操作:
  1. 在接口配置模式下,输入以下命令:
    wavelength wavelength-value
    注: 支持的波长范围为 1528.38 nm 至 1568.77 nm。
    OS10(conf-if-eth1/1/14)# wavelength 1530.00
  2. 使用以下命令查看您配置的光纤传输值:
    show interface phy-eth interface transceiver | grep "Tunable wavelength"
     OS10# show interface phy-eth 1/1/14 transceiver | grep "Tunable wavelength"
    
    SFP1/1/14 Tunable wavelength= 1530.000nm
    
    注: 要指定波长值,必须确切输入六位数字 — 在小数点前面四位,在小数点后面两位。值必须符合以下格式:ABCD.EF,例如,1545.23。任何不符合此格式的数字都会被拒绝,包括完整的数字,如 1568。但是,接受以下类型的值:1568.00。
