Temperature
Alarm
Normal -1,
Not Supported - 2,
Low Warn - 3,
High Warn - 4,
Low Alarm - 6
High Alarm - 7
Alarm status for temperature of fiber transceiver.
An
ionDMITemperatureEvt
event is sent when there is a warning
or alarm on DMI temperature
Transmit Bias
Current (uA)
(measured cur-
rent)
Transmit bias current on local fiber interface, in uA (microam-
peres). The sample screen above shows 14768 uA (micro-
amps).
Transmit Bias
Alarm
Normal -1,
Not Supported - 2,
Low Warn - 3,
High Warn - 4,
Low Alarm - 6
High Alarm - 7
Alarm status for transmit bias current on local fiber interface.
Transmit
Power (uW)
(measured power) Transmit power on local fiber measured in microwatts.
The sample screen above shows 240 uW (microwatts).
Transmit
Power (dBM)
(measured power)
Transmit power on local fiber measured in dBM (decibels rela-
tive to one milliwatt) which defines signal strength.
The sample screen above shows -6.126 dBM.

Low Alarm - 6
High Alarm - 7
Alarm status for transmit power on local fiber.
Supported
Media Length
9/125u Single-
mode Fiber (m)
Specifies the link length that is supported by the transceiver
while operating in single mode (SM) fiber. The unit of measure is
meters (m). The sample screen above shows N/A, indicating the
media is not applicable.
Supported
Media Length
50/125u Multi-
mode Fiber (m)
Specifies the link length that is supported by the transceiver
while operating in 50 micron Multimode (MM)
fiber. The value is in meters. The sample screen above shows
500 meters as the supported media length.
Supported
Media Length
62.5/125u MM Fi-
ber (m)
Specifies the link length that is supported by the transceiver
while operating in 62.5 micron Multimode (MM) fiber. The value
is in meters. The sample screen above shows 300 meters as the
supported media length.
Supported
Media Length
Copper (m)
Specifies the link length that is supported by the transceiver
while operating in copper cable. The value is in
meters. The sample screen above shows N/A, indicating the
media is not applicable.
