FTLX3815M3xx DWDM XFP Product Specification Nov 2014  
F i n i s a r  
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.  
The threshold adjustment input value is 2’s complement 7 bit value (-128 to  
+127). The default Rx threshold value will be approximately 0. Full range of  
adjustment provides at least a ±10% change in Rx threshold from the default  
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.  
8.5Gb/s Fibre-Channel CDR Bypass rate select:  
For 8G FC operation, write “1” to Byte 116, bit 1. Every time that the module is power  
cycled, this will need to be re-written (bit goes back to “0” and CDR is now set for  
10Gb/s operation) in order to operate properly at 8G FC.  
Contact your Finisar RSM or PLM for details on the CDR Bypass.  
Write “1” to Byte 116, bit 1. Every time that the module is power cycled, this will need  
to be re-written (bit goes back to “0” and CDR is now set for 10Gb/s operation) in order  
to operate properly at 8G FC.
