Interfacing the Transceiver
Communication is done by a serial 2-wire interface compatible to the I2C bus protocol. Refer to SFF-8472 for
a more detailed explanation of the registers:
Serial Transceiver ID as
defined in SFP MSA
Digital Optical Monitoring
The transceiver offers the ability to monitor important module parameter during operation. All five parameters
listed below are continuously monitored for getting information about the current module status. All data is
calibrated internally; there is no need for external post processing.
Temperature
Internally measured temperature data is represented as two’s complement of a signed 16-bit value in
increments of 1/256 °C over a range of -40 to +100 °C. Accuracy is better than +/-3 °C.
Supply Voltage (VCC)
Internally measured supply voltage. 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, which yields to a total range of 0 to +6.55 Volts.
Accuracy is better than +/-3 %.
Laser Bias Current
The DFB laser bias current is 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. Accuracy is better than +/-10 %.
Optical Transmitter Power
TX output power measurement is based on internal monitor diode feedback. 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.
Accuracy is better than +/-3 dB over a range of Pavg
