FTLF1421P1BTL-3G pluggable sfp product specification ? september 2010 f i n i s a r ? finisar corporation september 13, 2010 rev. a1 page 6 viii. digital diagnostic functions finisar FTLF1421P1BTL-3G sfp transceivers support the 2-wire se rial communication protocol as defined in the sfp msa 1 . it is very closely related to the e 2 prom defined in the gbic standard, with the sa me electrical specifications. the standard sfp serial id pr ovides access to identification information that describes the transceiver?s capabilities, standard in terfaces, manufacturer, and other information. additionally, finisar sfp transceivers provi de a unique enhanced digital diagnostic monitoring interface, which al lows real-time access to devi ce 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 pa rticular operating parameters are outside of a factory 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 b it address 1010001x (a2h), so the originally defined serial id memory map remains uncha nged. the interface is id entical 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 inte rface for sfp optical transceivers?. the operating and diagnostics informati on 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 seri al 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-protected. the negative edge clocks data from the sfp transc eiver. the serial data signal (sda, mod def 2) is bi-directional for serial data tr ansfer. the host uses sda in conjunction with scl to mark the start and end of serial pr otocol 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 1 or finisar application note an-2030. digital diagnostics for the FTLF1421P1BTL-3G are externally calibrated by default. please note that evaluation board fdb- 1018 is available with finisar moddemo software that allows simple to use comm unication over the 2-wire serial interface.
