 Finisar Corporation 

PRELIMINARY and Confidential

 

Page 8 

Rev C, February 2005 

IX.  Serial Communication Protocol 

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

1

. These SFPs use an Atmel AT24C01A 128 byte E

2

PROM with an address of A0h.  

For details on interfacing with the E

2

PROM, see the Atmel data sheet titled 

“AT24C01A/02/04/08/16 2-Wire Serial CMOS E

2

PROM.”

Finisar’s DWDM SFPs also support extended diagnostic features as described in Finisar 
Applications Note AN-2030, “Digital Diagnostic Monitoring Interface for Optical 
Transceivers”

2

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

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