As defined by MSA Finisar transceivers provide digital diagnostic functions via a 2 wire serial interface which allows real time access to the following operating parameters Transceiver temperature Laser bias current Transmitted optical power Received optical power Transceiver supply voltage TEC Temperature It also provides a sophisticated system of alarm and warning flags which may be used to alert end users when particular operating parameters are outside of a factory set normal range The operating and diagnostics information is monitored and reported by a Digital Diagnostics Transceiver Controller DDTC inside the transceiver which is accessed through the 2 wire serial interface When the serial protocol is activated the serial clock signal SCL pin is generated by the host The positive edge clocks data into the XFP transceiver into those segments of its memory map that are not write protected The negative edge clocks data from the XFP transceiver The serial data signal SDA pin is bi directional for serial data transfer The host uses SDA in conjunction with SCL to mark the start and end of serial protocol activation The memories are organized as a series of 8 bit data words that can be addressed individually or sequentially The 2 wire serial interface provides sequential or random access to the 8 bit parameters addressed from 000h to the maximum address of the memory For more detailed information in
