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.
