Digital Diagnostic Functions
The SFP support the 2-wire serial communication protocol as defined in the SFF 8472. Digital diagnostic
information are accessible over the 2-wire interface at the address 0xA2. Digital Diagnostics are
internally calibrated by default. A micro controller unit inside the transceiver gathers the monitoring
information and reports the status of transceiver.
Transceiver Temperature, internally measured, represented as a 16 bit signed twos complement value
in increments of 1/256 degrees Celsius, Temperature accuracy is better than ±3 degrees Celsius over
specified operating temperature and voltage.
Transceiver Supply Power, internally measured, represented as a 16 bit unsigned integer with the
voltage defined as the full 16 bit value (0 –65535) with LSB equal to 100 μVolt, yielding a total range of
0 to +6.55 Volts.
Transceiver TX bias current, internally measured, represented as a 16 bit unsigned integer with the
current defined as the full 16 bit value (0 –65535) with LSB equal to 2 μA, yielding a total range of 0 to
131mA. Accuracy is better than ±10% over specified operating temperature and voltage.
Transceiver TX output power, internally measured, represented as a 16 bit unsigned integer with the
power defined as the full 16 bit value (0 –65535) with LSB equal to 0.1 μW. Data is assumed to be based
on measurement of laser monitor photodiode current. Accuracy is better than ±3dB over specified
temperature and voltage. Data is not valid when the transmitter is disabled.
Transceiver RX received optical power, internally measured, represented as a 16 bit unsigned integer
with the power defined as the full 16 bit 35 value (0 –65535) with LSB equal to 0.1 μW. Accuracy is
better than ±3dB over specified temperature and voltage.
