FTRX-3811-3xx 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-3811-3 becomes operational within 60
seconds of power-up. This is due to the time required for the EML to reach its optimum
operating temperature.

Notes:
1. Corresponds to approximately 0.8 nm.
2. X = Specified ITU Grid wavelength.
3. Measured with a host jitter of 50 mUI peak-to-peak.
4. Measured with a host jitter of 7 mUI RMS.
5. Measured at 1528-1600nm with worst ER; BER<10-12; PRBS31.
6. Equivalent to –22.1 dBm OMA at ER = 9 dB.
7. Dispersion penalty should be measured in loopback on a 1450 ps/nm fiber link.
