FWDM-1629-XX DWDM SFP Preliminary Product Specification – February 2005
F i n i s a r
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 E2PROM with an address of A0h.
For details on interfacing with the E
2PROM, see the Atmel data sheet titled
“AT24C01A/02/04/08/16 2-Wire Serial CMOS E
2PROM.”4
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.
