VIII. Digital Diagnostic Functions

Finisar FTLF1421P1xTL SFP transceivers support the 2-wire serial communication

protocol as defined in the SFP MSA1. It is very closely related to the E2PROM 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 E2PROM 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 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 documentation1 or Finisar Application

Note AN-2030.

Digital diagnostics for the FTLF1421P1xTL 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.
