(Does not apply to all OC-N cards) The Transceiver subtab shows the OC-N and MRC-N card optical
power received (OPR), optical power transmitted (OPT), and laser bias current (LBC) from the line card and stores these values with the PM counts for the 15-minute and 1-day periods. The physical layer performance parameters consist of normalized and non-normalized values of LBC, OPT, and OPR. For more information, see
Transceiver. For a list of ONS nodes and cards that support this subtab, see
Maintenance.
