IX. Serial Communication Protocol

All Finisar SFPs support the 2-wire serial communication protocol to provide module ID

information as outlined in the SFP MSA1. These SFPs use an Atmel AT24C01A 128 byte

E2PROM with an address of A0h. For details on interfacing with the E2PROM, see the

Atmel data sheet titled “AT24C01A/02/04/08/16 2-Wire Serial CMOS E2PROM.”3

Finisar SFPs also support diagnostic features as described in Finisar Applications Note AN-

20304 and SFF-84725, “Digital Diagnostic Monitoring Interface for Optical Transceivers”.

A controller IC that monitors system parameters such as laser current, module temperature,

transmitter power, and received power is accessible at address A2H. In addition, Finisar’s

DWDM SFPs provide extended set of ID information and diagnostic features as described

in the DWDM SFP MSA6.

I2C clock speed, digital diagnostic accuracy and digital diagnostic range can be found in the

table below. Values in the table represent the worst-case values over temperature, voltage,

and life.
