6. o identification information that describes the transceiver s capabilities standard interfaces manufacturer and other information Additionally Finisar SFP transceivers provide a 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 EPROM that is accessible over a 2 wire serial interface at the 8 bit address 1010000X AOh The digital diagnostic monitoring interface makes use of the 8 bit address 1010001 X 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 The operating and diagnostics information is monitored and reported by a Digital Diagnostics Transceiver Controller DDTC inside the transceiver which is accessed through a 2 wire serial interface When the serial protocol is activated the serial clock signal SCL Mod Def 1 1s generat
