Digital Diagnostic Functions Finisar FWDM-1519-7D-xx SFP transceivers support the 2-wire serial communication protocol as defined in the draft SFP MSA1 . It is very closely related to the E2 PROM defined in the GBIC standard, with the same electrical specifications. The standard SFP serial ID provides access to identification information that describes the transceiver’s capabilities, standard interfaces, manufacturer, and other information. Additionally, Finisar SFP transceivers provide a unique enhanced digital diagnostic monitoring interface, which allows real-time access to device operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power and transceiver supply voltage. It also defines a sophisticated system of alarm and warning flags, which alerts end- users when particular operating parameters are outside of a factory set normal range. The SFP MSA defines a 256-byte memory map in E2 PROM that is accessible over a 2-wire serial interface at the 8 bit address 1010000X (A0h). The digital diagnostic monitoring interface makes use of the 8 bit address 1010001X (A2h), so the originally defined serial ID memory map remains unchanged. The interface is identical to, and is thus fully backward compatible with both the GBIC Specification and the SFP Multi Source Agreement. The complete interface is described in Finisar Application Note AN2030: “Digital Diagnostics Monitoring Interface for SFP Optical Transceivers”.
