Transceiver

---

(Does not apply to all OC-N cards) The Transceiver subtab shows OC-N port 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.

Port	Displays the card port number.
Non-normalized LBC (mA)	Displays the actual operating value of laser bias current (mA) for the specified card port. This value should be somewhat consistent from port to port and cannot be configured.
Non-normalized OPR (dbm)	Displays the actual operating value of optical power received (dBm) for the specified card port. This value varies from port to port because of received optical signal power differences.
Non-normalized OPT (dbm)	Displays the actual operating value of optical power transmitted (dBm) for the specified card port. This value should be somewhat consistent from port to port and cannot be configured.
Refresh	Refreshes the tab fields.
Help	Displays context-sensitive help.
