BERT Area Description
BER
Displays the current bit error rate.
Green: No errors detected since the last reset
Red: At least one error has been detected
Errors
The number of bits errors.
Green: No errors detected within the last 100mS
Red: At least one error has been detected within the last
100mS
Time The total test time since the last reset (hours:minutes:seconds)
Bit Rate Current data rate setting
Pattern Current pattern setting
Lock / LOL
Displays the pattern detector/CDR status:
“Lock” Green: CDR and pattern detector are locked
“LOL” Red: CDR or pattern detector are not locked
SFP Area Description
Rx Power
Displays the received optical power level as reported by the SFP /
SFP+. The color indicates if the receiver has been selected as the
BERT measurement interface. This field is displayed only when a
transceiver is inserted.
Yellow: Indicates the SFP receiver is the active interface
Grey: Indicates the SFP receiver is not the active interface
Tx Power
Displays the transmitted optical power level as reported by the SFP /
SFP+. The up/down arrow following the measurement indicates the
output polarity. The color indicates if the transmitter has been
enabled. This field is displayed only when a transceiver is inserted.
Yellow: Indicates the SFP transmitter is active
Grey: Indicates the SFP transmitter is not active
Temperature Displays the SFP/SFP+ temperature
Wavelength Displays the SFP/SFP+ transmitter wavelength
SMA Area Description
SMA Rx
Displays the received electrical level as a percentage of full scale.
The color indicates if this input has been selected as the BERT
measurement interface.
Yellow: Indicates the SMA input is the active interface
Grey: Indicates the SMA input is not the active interface
SMA Tx
Displays the state of the electrical SMA output. The up/down arrow
following the measurement indicates the output polarity. The color
indicates if the output has been enabled.
Yellow: Indicates the output is active
Grey: Indicates the output is not active
Conf Button Pressing this button displays the configuration screens as described
in the following section
Reset Button Pressing this button resets all BERT counters
