Command introduced before Junos OS Release 10.2 for J-EX Series switches.
Display diagnostics data and alarms for Gigabit Ethernet optical transceivers (SFP or
SFP+) installed in J-EX Series switches. The information provided by this command is
known as digital optical monitoring (DOM) information.
Thresholds that trigger a high alarm, low alarm, high warning, or low warning are set by
the transponder vendors. Generally, a high alarm or low alarm indicates that the optics
module is not operating properly. This information can be used to diagnose why a
transceiver is not working.
interface-name —Name of the interface associated with the port in which the transceiver
is installed: ge-fpc/pic/port

Field Description
Displays the name of the physical interface.
Displays the magnitude of the laser bias power setting current, in
milliamperes. The laser bias provides direct modulation of laser diodes and
modulates currents.
Displays the laser output power, in milliwatts (mW) and decibels referred to
1.0 mW (dBm).
Displays the temperature, in Celsius and Fahrenheit.
Displays the voltage, in Volts.
