Dell EMC SmartFabric OS10 User Guide Release 10.5.0

Configuring wavelength

You can configure optical transmission wavelength values for SPF+ optics. This configuration enables you to fine tune the laser wavelengths and frequencies up to two decimal places in the nanometer scale.

1. In interface configuration mode, enter the following command:

   wavelength wavelength-value

   NOTE The supported wavelength range is from 1528.38 nm to 1568.77 nm.

   OS10(conf-if-eth1/1/14)# wavelength 1530.00

2. View the optical transmission values that you configured using the following command:
   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
   

   NOTE To specify the wavelength value, you must enter exactly six digits - four before and two after the decimal point. The value must conform to the following format: ABCD.EF; for example, 1545.23. Any number that does not conform to this format is rejected including whole numbers such as 1568. However, the following type of values are accepted: 1568.00.
