In the response above the Status is “OK” (6 lines from the bottom).
If the system responds with an error message the fibre link need to be checked. If
there is nothing wrong with the link it is possible that the fibre loss is too big for the
system to be able to compensate for it.
Go through all racks and all fibre optic converters one by one and initiate the
compensation process.
Note! Earlier
repeater versions
If the OMU is connected to repeaters
of an earlier release, which has a fibre
optic converter of the type in the
photograph, these commands will not
work.
Instead a default value needs to be
defined by using the command OLC.
Please see OMU Command and
Attributes for more detailed
information regarding this command.
The OLC value should be set to 6dB. This value ensures that the amplification value
on the link will be 0dB at 0dB optical loss.
Example
SET OLC 1:2 6
Adjusts the attenuation in the fibre optic converter unit in rack 1, slot 2 to 6 dB.
Go through all racks and slots that are connected to a repeater of this kind and send
this command.
Continue with the Chose “Actions/Perform Optical Loss Adjustment” from the drop down menu.
