Usage
Information
The wavelength can be configured only on a tunable 10–Gigabit SFP+ optic. The wavelength range is
from 1528.3 nm to 1568.77nm.
If you configure the wavelength on a non-tunable optic, there is no change to the existing wavelength.
The configured wavelength is saved in the running configuration and is applicable, when a tunable optic is
used.
If you do not configure the wavelength on an inserted tunable optic, the existing wavelength is used.
Example
The following example shows the wavelength set for a tunable 10–Gigabit SFP+ optic:
