Rev J, August 2004
IX. Serial Communication Protocol
All Finisar optical GBICs implement serial identification features described for ‘Module
Definition “4”’ as outlined in Annex D of the GBIC Specification
1. These GBICs use an
Atmel AT24C01A 128 byte E
2PROM at address 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.”3
Finisar’s DWDM GBICs 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.
