FWLF16217Dxx SFP Product Specification – May 2010

IX.

Digital Diagnostic Functions

All Finisar SFPs support the 2-wire serial communication protocol outlined in the SFP

MSA⁵. These SFPs use an Atmel AT24C01A 128 byte E²PROM with an address of A0h

(see table below for E²PROM contents). For details on interfacing with the E²PROM, see

the Atmel data sheet titled “AT24C01A/02/04/08/16 2-Wire Serial CMOS E²PROM.”⁶

Finisar’s CWDM SFPs also support extended diagnostic features as described in Finisar

Applications Note AN-2030, “Digital Diagnostic Monitoring Interface for Optical

Transceivers”⁷, and additional information is available in SFF standard titled: “Digital

Diagnostic Monitoring Interface for Optical Transceivers⁸(SFF-8472 rev9.3). A

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

transmitter power, and received power is accessible at address A2H.

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.
