050-356 Product Brief
PCB Mount CWDM Dual-Transmitter
100 Mbps – 2.5 Gbps SMF, 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.
