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.

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

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.

8.

Measured at BER<10
