VIII. Serial Communication Protocol
All Finisar optical GBICs are ‘Module Definition “4”’ and support the 2 wire serial
communication protocol outlined in the GBIC Specification
1. These GBICs use an
Atmel AT24C01A 128 byte E
2PROM (with an address of 1010000X). 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.”6
All Finisar optical GBICs also incorporate a controller IC that monitors system
parameters such as laser current, laser temperature, and, in the case of
13xx/14xx/15xx/16xx nm parts, transmitted power. For a complete description of how to
use Finisar’s extended features, see Finisar’s Application Note AN-2030
