Parameter
Description
Vendor Revision
Displays the revision number of the serial number provided by the vendor
for the SFP module.
Laser Wavelength (nm)
Display’s the SFP module’s laser wavelength. For CSFP modules, two
wavelengths are displayed. This parameters is not relevant for copper SFPs.
Link Length SM Fiber (km)
The maximum length of the cable (in km) for single mode fiber cables.
Link Length OM1 Fiber (m)
The maximum length of the cable (in meters) for OM1 multi-mode fiber
cables.
Link Length OM2 Fiber (m)
The maximum length of the cable (in meters) for OM2 multi-mode fiber
cables.
Link Length OM3 Fiber (m)
The maximum length of the cable (in meters) for OM3 multi-mode fiber
cables.
Optical Diagnostics Supported
Displays whether the SFP module supports DDM monitoring. For modules
that do not support DDM monitoring, the parameters described in
15.12.2
Displaying Dynamic (DDM) Information about an SFP Module (CLI)

Parameter
Description
Transceiver Present
Indicates whether an SFP module is attached to the interface.
RX Power Level (dBm)
The SFP module’s current RX power signal strength (in dBm).
TX Power Level (dBm)
The SFP module’s current TX power signal strength (in dBm).
Bias Current (mA)
The laser bias current of the SFP module (in mA)
Temperature
The current temperature of the SFP module (displayed in both C° and F°).
If no signal is being received, RX Power Level is displayed as -40 dBm.
If the Admin status of the port is Down, the TX Power Level is displayed as -40
DBm and the Bias Current is displayed as 0 mA.
The Temperature is always shown as long as the SFP module is inserted in the
port.
