VIII. 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
2
PROM at address 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.”

The FTL-8519-3D also supports extended diagnostic features as described in Finisar
Applications Note AN-2030, “Digital Diagnostic Monitoring Interface for Optical
Transceivers”
8
, and additional information is available in SFF standard titled: “Digital
Diagnostic Monitoring Interface for Optical Transceivers”
9
(SFF-8472 Rev. 9.3). 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.
