OS Command Line Reference Guide.
Version Description
9.10(0.0) Introduced on the S6000, S6000–ON, S5000, S4810, S4820T, S3048–ON, S4048–ON,
M I/O Aggregator, FN I/O Module, MXL, C9010, S3100 series, and Z9100-ON.
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:
Dell(conf-if-gi-1/1)# wavelength 1528.30
