FTLX3811M3xx DWDM XFP Product Specification – January 2011 F i n i s a r
© Finisar Corporation 11-January-2011 Rev C1 Page 6
Please note that the Transmitter of the FTLX3811M3xx becomes operational within 60
seconds of power-up. This is due to the time required for the EML to reach its optimum
operating temperature.
