FTLF1324P2XTY industrial temp. sfp product specification ? february 2007 f i n i s a r ? finisar corporation february 24, 2007 rev. h page 6 viii. digital diagnostic functions finisar FTLF1324P2XTY sfp tr ansceivers support the 2-wi re serial communication protocol as define d 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 interf aces, manufacturer, a nd other information. additionally, finisar sfp transceivers provide a unique enhanced digital diagnostic monitoring interface, which allows real-time access to device operati ng parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power and transceiver supply volta ge. it also defines a sophis ticated system of alarm and warning flags, which alerts e nd-users when particular opera ting parameters are outside of a factory set normal range. the sfp msa defines a 256-byte memory map in e 2 prom that is a ccessible over a 2-wire serial interface at the 8 bit address 1010000x (a 0h). the digital diagnostic monitoring interface makes us e of the 8 bit address 1010001x (a2h), so the originally defined serial id memory ma p remains unchanged. the interfa ce 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 inte rface for sfp optical transceivers?. the operating and diagnostics information is monitored and reported by a digital diagnostics transceiver contro ller (ddtc) inside the transceiver, which is accessed through a 2-wire serial interface. when the seri al protocol is activat ed, 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 wr ite-protected. the negative edge clocks da ta from the sfp transceiver. th e serial data signal (sda, mod def 2) is bi-directional for serial data tr ansfer. the host uses s da in conjunction with scl to mark the start and end of serial pr otocol activation. the me mories are organized as a series of 8-bit data wo rds that can be addressed i ndividually or sequentially. for more information, please see the sfp msa documentation 1,6 or finisar application note an-2030. FTLF1324P2XTY transceivers can be used in host systems that require either internally or externally calibrated digital diagnostics. please note that eval uation board fdb-1018 is availa ble with finisar moddemo software that allows simple to use comm unication over the 2-wire serial interface.
