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
• TEC Temperature
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 interfa ce. When the seri al 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 dat a from the XFP transcei ver. 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.
For more detailed information, including memory map definitions, please see the XFP
MSA documentation1.
Receiver Threshold Adjustment
The FTLX6811MCC and FTLX6814MCC also provide access to receiver decision
threshold adjustment via 2-wire serial interface, in order to improve receiver OSNR
performance based on specific link conditions. It is implemented as follows:
• Rx Threshold of XFP transceivers will be factory-set for optimized performance
in non-FEC applications. This will be the default value during both cold start
(power-up) and warm start (module reset).
• The transceiver supports adjustment of Rx Threshold value by the host through
register 76d, table 01h. This is intended to be used in FEC applications.
• Register 76d, table 01h is a volatile memory. Therefore if the transceiver is
power-cycled, the register starts up with a value of 00h which corresponds to the
default Rx Threshold value.
FTLX6811MCC and FTLX6814MCC T-XFP Pr oduct Specification
Finisar Corpor ation October 2015 Rev. B1 Page 9
• The threshold adjustment input value is 2’s complement 7 bit value (-128 to
+127), with 0 corresponding to default Rx threshold value. Full range of
adjustment provides at least a ±10% change in Rx threshold from the default
value.
• An incr ease in R xDTV v alue sets t he thres hold closer t o the “1 ” valu e of the eye.
The Default setting is the factory tuned optimized set point and is not necessarily
the 50% RxDTV value.
SBS suppression, dither tone
Set Address 111, bit 1 to “0” to enable tone, “1” to disable dither tone (defaults:
frequency = 40kHz , tone is disabled). Please contact your Finisar RSM or PLM if
specific amplitudes and frequencies are needed for SBS suppression.

Upon a power up, the module will go to a default wavelength (Finisar default channel is
1549.716nm) or the last channel set by the host. If Tx_DIS is asserted upon power up, the
laser will be disabled and the set wavelength will be cleared. Once the Tx_DIS is de-
asserted, the firmware will maintain the laser in an off state until the host sets the desired
ITU channel. If the module is powered-down before the ITU channel was set and
TX_DIS de-asserted, the module will re-start at the default channel. See the following
startup channel flowchart.
Flow Chart of Startup Channel
A desired wavelength can be commanded by the user by writing into Bytes 72 (MSB)
and 73 (LSB). Wavelength control command:

Thus for instance a target wavelength of 1556.55 nm would correspond to 79h (MSB)

desired frequency channel can be commanded by the user by writing into Bytes 112
