Finisar FTLF1428P2BNV network transceiver module
Contents
1. 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 is generated by the host The positive edge clocks data into the SFP transceiver into those segments of the E7PROM 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 or Finisar Application Note AN 2030 FTLF1428P2BNV transceivers can be used in host systems that require either internally or externally calibrated digital diagnostics Please note that e2. 1 Laser Products and comply with US FDA regulations These products are certified by TUV and CSA to meet the Class 1 eye safety requirements of EN IEC 60825 and the electrical safety requirements of EN IEC 60950 Copies of certificates are available at Finisar Corporation upon request Finisar Corporation October 29 2008 Rev Cl Page 5 FTLF1428P2BNV Product Specification October 2008 Finisar VIN Digital Diagnostic Functions Finisar FTLF1428P2BNV SFP transceivers support the 2 wire serial communication protocol as defined in the SFP MSA It is very closely related to the EPROM 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 E7PROM that is accessible over a 2 wire serial interface at the 8 bit address 1010000X AOh
