OPTICAL MASTER UNIT
PRODUCT DESCRIPTION AND USER’S MANUAL

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
repeaters
Chose “Actions/Perform Optical Loss Adjustment” from the drop down
menu.
The system will respond with a description as below.
Note!
This command does not exist in repeaters with the earlier type of fibre optic
converters, equivalent to the note above regarding OLC. For these repeaters
disregard this step.
