The PCB Mount Transceiver features EEPROM for Serial ID, which contains the product data stored for retrieval by host
equipment. This data is accessed via the 2-wire serial EEPROM protocol in compliance with the industry standard SFP
Multi-Source Agreement. The base EEPROM memory, bytes 0-255 at memory address 0xA0, is organized in compliance
with SFF-8074i.
As an enhancement to the conventional SFP interface defined in SFF-8074i, the PCB Mount Transceiver is compliant to
SFF-8472 (digital diagnostic interface for optical transceivers). This new digital diagnostic information is stored in bytes 0-
255 at memory address 0xA2.Using the 2-wire serial interface defined in the MSA, the PCB Mount Transceiver provides
real time temperature, supply voltage, Laser bias current and Transmitter output power. These parameters are internally
calibrated, per the SFF-8472 MSA. The digital diagnostic interface also adds the capability to monitor for Receiver Loss
