XFP Transceiver Port Data
State Description
Laser bias current Magnitude of the laser bias power setting current (measured, minimum and maximum limits),
in milliamperes (mA).
The laser bias provides direct modulation of laser diodes and allows the user to monitor the
“health” of the laser.
Vcc [V] Magnitude of the supply voltage to the transceiver (measured, minimum, and maximum limits), in
Volts (V).
AUX1
(4)
(for XFP transceivers only) Auxiliary measurement 1 for XFP transceivers—defined in Byte 222 Page 01h in INF-8077i.
AUX2
(4)
(for XFP transceivers only) Auxiliary measurement 2 for XFP transceivers—defined in Byte 222 Page 01h in INF-8077i.
Active alarms Transceiver alarm conditions for specified port/slot:
• NONE—No alarm conditions exist
• Condition—Alarm condition is in effect.
(1) Use part number XFP-OC192-LR2 when ordering the XFP transceivers with 10GE ZR functionality.
(2) In Releases 6.1.4 and 6.1.5, DWDM XFP transceivers support only ITU channels 35,36,37,53,and 54.
(3) See theTroubleshoot with System Power and Alarm LEDs section for the lists of alarms and warnings supported by
the SFP and XFP transceivers.
(4) See the “XFP Transceivers Measurements and Threshold Values” table for a list of auxiliary input types monitored
by each auxiliary A/D channel of the XFP transceivers.
