Starting with release
Cisco IOS XE Release 3.13, Digital Optical Monitoring (DOM) is supported for
the SFP, SFP+, and XFP transceiver modules.
DOM is supported for
ASR 900 RSP3 Module.

DOM supported transceivers, see
For a list of

Aggregation Services Router Hardware Installation Guide.
Real time DOM data is
collected from SFPs, SFP+, and XFPs periodically and compared with warning and
alarm threshold table values.
The DOM data
collected are transceiver transmit bias current, transceiver transmit power,
transceiver receive power, and transceiver power supply voltage.
The syslog messages
are displayed when alarm threshold values are crossed.
parameters are not monitored when the port is in ADMIN-DOWN.
