Interfaces
command can be used to limit the range of sweeping for the automatic control mode and thus achieve faster
link up.
Parameters
dispersion-start — Specifies the lower range limit for the dispersion compensation.
Values
Default
dispersion-end — Specifies the upper range limit for the dispersion compensation.
Values
Default
sweep
Syntax sweep start dispersion-start end dispersion-end
Context config>port>dwdm>coherent
Description This command allows users to configure the dispersion sweep 'start' and 'end' values for the automatic
mode of coherent control. If the user knows the approximate or theoretical residual dispersion of the link,
this command can be used to limit the range of sweeping for the automatic control mode and thus achieve
faster link up.
Parameters dispersion-start — Specifies the lower range limit for the dispersion compensation.
Values
Default
dispersion-end — Specifies the upper range limit for the dispersion compensation.
Values
Default
rxdtv-adjust
Syntax [no] rxdtv-adjust
Context config>port>dwdm
Description
This command enables you to adjust the optical receive decision threshold voltage (RxDTV).
Default
no rxdtv-adjust
