PCB Mount Dual-Transmitter for Single Mode Fiber

100 Mbps – 4.25 Gbps, FP Lasers, 3.3V

Digital Diagnostic Interface and Serial Identification (EEPROM)

The PCB mount Dual-Transmitter is derived from the SFF-8074i SFP specification and with SFF-8472, the SFP

specification for Digital Diagnostic Monitoring Interface, but modified to account for Dual-Transmitter functionality. Both

specifications can be found at http://www.sffcommittee.org.

FIGURE 4 – DIGITAL DIAGNOSTIC MEMORY MAP OVERVIEW

The PCB mount Dual-Transmitter 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,

derived from with the industry standard SFP Multi-Source Agreement but modified to account for Dual-Transmitter

functionality. The base EEPROM memory, bytes 0-255 at memory address A0h, is organized in compliance with SFF-

8074i.
