318
Displays the nominal bit rate of the transceiver.
Temperature
Displays the internally measured transceiver temperature. Temperature accuracy is
vendor specific but must be better than 3 degrees Celsius over specified operating
temperature and voltage.
Vcc
Displays the internally measured transceiver supply voltage. Accuracy is vendor
specific but must be better than 3 percent of the manufacturer's nominal value over
specified operating temperature and voltage. Note that in some transceivers,
transmitter supply voltage and receiver supply voltage are isolated. In that case,
only one supply is monitored. Refer to the device specification for more detail.
Mon1 (Bias)
Displays the measured TX bias current in uA. Accuracy is vendor specific but must
be better than 10 percent of the manufacturer's nominal value over specified
operating temperature and voltage.
Mon2 (TX PWR)
Displays the measured coupled TX output power in mW. Accuracy is vendor specific
but must be better than 3dB over specified operating temperature and voltage.
Data is assumed to be based on measurement of a laser monitor photodiode
current. Data is not valid when the transmitter is disabled.
Mon3 (RX PWR)
Displays the measured received optical power in mW. Absolute accuracy is
dependent upon the exact optical wavelength. For the vendor specified wavelength,
accuracy should be better than 3dB over specified temperature and voltage. This
accuracy should be maintained for input power levels up to the lesser of maximum
transmitted or maximum received optical power per the appropriate standard. It
should be maintained down to the minimum transmitted power minus cable plant
loss (insertion loss or passive loss) per the appropriate standard. Absolute accuracy
beyond this minimum required received input optical power range is vendor
specific.
