Digital Diagnostic Functions
All Finisar SFPs support the 2-wire serial communication protocol outlined in the SFP
MSA
5. These SFPs use an Atmel AT24C01A 128 byte E2PROM with an address of A0h
(see table below for E
2PROM contents). For details on interfacing with the E2PROM, see
the Atmel data sheet titled “AT24C01A/02/04/08/16 2-Wire Serial CMOS E
2PROM.”6
Finisar’s CWDM SFPs also support extended diagnostic features as described in Finisar
Applications Note AN-2030, “Digital Diagnostic Monitoring Interface for Optical
Transceivers”
7, and additional information is available in SFF standard titled: “Digital
Diagnostic Monitoring Interface for Optical Transceivers
8
(SFF-8472 rev9.3). 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.
