ftrj1522p1xtl pluggable sfp product specification - april 2005 f i n i s a r ? finisar corporation april 26, 2005 rev.d page 6 viii. digital diagnostic functions finisar ftrj1522p1xtl sfp transceivers support the 2-wire serial 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 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 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 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 e 2 prom 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 1 or finisar application note an-2030. digital diagnostics for the ftrj1522p1xtl are externally calibrated by default. 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.
