Finisar’s 40km DWDM FTLX3912M3xx Small Form Factor 10Gb/s XFP transceivers
comply with the current XFP Multi-Source Agreement (MSA) Specification1. The
transmitter specification is based upon SONET OC-192 IR-2, OC-192 IR-3, SDH STM
S-64.2b, STM S-64.3b and 10-Gigabit Ethernet 10GBASE-ER/EW per IEEE 802.3ae but
uses an APD ROSA for additional link budget. Digital diagnostics functions are available
via a 2-wire serial interface, as specified in the XFP MSA. The transceiver is RoHS
compliant and lead free per Directive 2002/95/EC3, and Finisar Application Note AN20384.

VIII. Digital Diagnostics Functions
As defined by the XFP MSA1, Finisar XFP transceivers provide digital diagnostic
functions via a 2-wire serial interface, which allows real-time access to the following
operating parameters:





Transceiver temperature
Laser bias current
Transmitted optical power
Received optical power
Transceiver supply voltage
It also provides a sophisticated system of alarm and warning flags, which may be used to
alert end-users when particular operating parameters are outside of a factory-set normal
range.
The operating and diagnostics information is monitored and reported by a Digital
Diagnostics Transceiver Controller (DDTC) inside the transceiver, which is accessed
through the 2-wire serial interface. When the serial protocol is activated, the serial clock
signal (SCL pin) is generated by the host. The positive edge clocks data into the XFP
transceiver into those segments of its memory map that are not write-protected. The
negative edge clocks data from the XFP transceiver. The serial data signal (SDA pin) 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. The 2-wire
serial interface provides sequential or random access to the 8 bit parameters, addressed
from 000h to the maximum address of the memory.

MSA documentation1.
8.5Gb/s Fibre-Channel:
To operate the FTLX3912M3xx at 8.5Gb/s Fibre-Channel, the EEPROM-Table 0, Byte
117, Bit 0 must be set as follows; .
 EEPROM Byte 117, Bit 0, value “1” for 8GFC:
 EEPROM Byte 117, Bit 0 value “0” for 10Gb/s rates:
o (It is also possible to bypass the CDRs with, Byte 111, Bit 0.)
By default, a power cycling the transceiver will return the transceiver to normal 10Gb/s
operation with the CDRs active.
