Diagnostic Monitoring Interface (DMI)
The following DMI port screen and explanation table contain brief definitions of the DMI support offered on
some SFP Transceiver Modules. For further information, see the help option on Transition Networks Focal Point,
ION System, and other GUIs.
Note:
This feature is not available on all devices and may vary between products.
See the related manual for more information.
DMI Parameter
Description
DMI Rx Power
Measured receive optical power in microwatts and in decibels relative to 1mW.
DMI Rx Power Alarm
Alarm status of measured receive optical power.
DMI Temp
Internally measured temperature of transceiver in degrees Celsius and Fahrenheit.
DMI Temp Alarm
Alarm status for internally measured temperature of the transceiver.
DMI Bias Current
Measured transmit bias current in microamperes.
DMI Bias Alarm
Alarm status for measured transmit bias current for the interface.
DMI Tx Power
Measured transmit power in microwatts and in decibels relative to 1mW.
DMI Tx Power Alarm
Alarm status of measured transmit power.
Rx Power Intrusion
Threshold
Tells the converter to stop passing traffic when the receive power drops below the
new threshold. This feature is sometimes referred to as 'Intrusion Detection
’
, since
tapping into a fiber to intercept traffic leads to a reduction in receive power. This
value can be entered in microwatts or in decibels relative to 1mW.
TN-SFP distances, TX power, RX power, and link budgets can be found on Transition Networks
. The fiber
optic transmitters on this device meet Class I Laser safety requirements per IEC-825/CDRH standards and comply
with 21 CFR1040.10 and 21CFR1040.11. WARNING: Visible and invisible laser radiation when open. Do not stare
into the beam or view the beam directly with optical instruments. Failure to observe this warning could result in
an eye injury or blindness.
