FTRX-3812S3xx Amplified DWDM XFP Product Specification – September 2007
F i n i s a r
IV.
Optical Characteristics (EOL, TOP = -5 to 70°C, VCC5 = 4.75 to 5.25 Volts)
Please note that the Transmitter of the FTRX-3811S3xx becomes operational within 60
seconds of power-up. This is due to the time required for the EML to reach its optimum
operating temperature.
