Digital Diagnostic Functions
Finisar FWDM-1519-7D-xx SFP transceivers support the 2-wire serial communication
protocol as defined in the draft SFP MSA
1. It is very closely related to the E2PROM
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 E
2PROM 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 AN-
2030: “Digital Diagnostics Monitoring Interface for SFP Optical Transceivers”.
