Digital Diagnostic Functions Finisar FTLX3871DCCxx 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 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 complete interface is described in Finisar Application Note AN2030: “Digital Diagnostics Monitoring Interface for SFP Optical Transceivers” 7. 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. For more information, please see the SFP MSA documentation6 and Finisar Application Note AN-2030. Please note that evaluation board FDB-1027 is available with Finisar ModDEMO software that allows simple to use communication over the 2-wire serial interface.

Internally measured 2. The accuracy of the Tx bias current is 10% of the actual current from the laser driver to the laser X. SFF-8431 Power-up Sequence The typical power consumption of the FTLX3871DCCxx may exceed the limit of 1.5W specified for the Power Level II transceivers in [1], for which a power-up sequence is recommended. However, the FTLX3871DCCxx 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 power-up sequence specified for transceivers exceeding 1W, as per [1]. In power level I, the FTLX3871DCCxx does not carry traffic, but the 2-wire serial communication is active. Please refer to [1] and Finisar Application Note AN-2076 for additional details. XI. Receiver Decision Threshold Control The host can control the Receiver Decision Threshold (RxDT) of Finisar FTLX3871DCCxx SFP+ transceivers via the 2-wire serial communication, by setting the byte 131 of Table 02h. The availability of this function is indicated in Bit 3, Byte 64 of A0h in the serial ID section. Byte 131 is a 2's complement 7 bit value (-128 - +127) The decision threshold set is given by: RxDT = default RxDT + [Byte(131)/256]*100%. On power-up the byte 131 defaults to 0, corresponding to the RxDT optimum value. The actual RxDT range the formula covers is about ±20% around the default optimum value.
