FTLF1326P3BTL product specification ? august 2015 ? finisar corporation august 2015 rev. e1 page 6 viii. digital diagnostic functions finisar FTLF1326P3BTL sfp+ transceivers support the 2- wire serial communication protocol as defined in the sfp msa 6 . it is very closely related to the e 2 prom 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 temperat ure, 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 fact ory set normal range. the sfp msa defines a 256 - byte memory map in e 2 prom 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 applica tion 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 accesse d 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 e 2 prom that are not write - prot ected. 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 memo ries 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 3 , 6 or finisar application note an - 2030. FTLF1326P3BTL transceivers can be used in host syste ms that require either internally or externally calibrated digital diagnostics. please note that evaluation board fdb - 1018 is available with finisar moddemo software that allows simple to use communication over the 2 - wire serial interface.
