Digital Diagnostic Functions All Finisar SFPs support the 2-wire serial communication protocol outlined in the SFP MSA6. These SFPs use an Atmel AT24C01A 128 byte E2PROM with an address of A0h (see table below for E2PROM contents). For details on interfacing with the E2PROM, see the Atmel data sheet titled “AT24C01A/02/04/08/16 2-Wire Serial CMOS E2PROM.”7 Finisar’s CWDM SFPs also support 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 Transceivers9 (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.
