PCB Mount Bi-Directional 1310/1550 Single Fiber

Transceiver, 125 Mbps – 1.25 Gbps, SMF, 3.3V

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 of the ATMEL AT24C01A or similar, 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. The I2C accessible memory page address 0xB0 is

used internally by SFP for the test and diagnostic purposes and it is reserved.

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, laser average output power and received input power. These

parameters are internally calibrated, per the SFF-8472 MSA. The digital diagnostic interface also adds the capability to
