Digital Diagnostic Functions Finisar FTLX6871/72MCC Tunable SFP+ transceivers support the 2-wire serial communication protocol as defined in the SFP MSA1. It is very closely related to the memory map 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 T-SFP+ transceivers provide a 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 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 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 E2PROM 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. Finisar Corporation October 2015 Rev. B1 Page 7 FTLX6871/72MCC Product Specification IX.

XII. SFF-8431 Power-up Sequence The typical power consumption of the FTLX6871/72MCC exceeds the limit of 1.5W specified in the SFF-8431 for the Power Level II device, for which the SFF-8431 recommends a power-up sequence. Per the SFF-8431, at the power-on a Power Level II transceiver can stay in Power Level I until the host enables the transceiver to complete its power-up sequence, reaching its operating power consumption into Power Level Mode II. Please, refer to SFF-8431 and Finisar Application Note AN-20767 for additional details. The FTLX6871/72MCC is factory set to power-up directly to its operating conditions in Power Level Mode II. Upon request, it can be factory set to follow the above power-up sequence at the power-on. In power level I, the FTLX6871/72MCC does not carry traffic, but the 2-wire serial communication is active.
