5. 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 generated by the host The positive edge clocks data into the SFP transceiver into those segments of the EPROM that are not write protected The negative edge clocks data from the SFP transceiver The serial data signal SDA Mod Def 2 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 For more information please see the SFP MSA documentation and Finisar Application Note AN 2030 Please note that evaluation board FDB 1027 is available with Finisar ModDEMO software that allows simple to use communication over the 2 wire serial interface Finisar Corporation November 21 2007 Rev B Page 7 FTLF8528P2BCV Pluggable SFP Product Specification November 2007 F EHISGAF IX Digit
