a
Receiver sensitivity is –25.0 dB for 1270–1450 Nm window
b
Measured at 3600 ps/Nm dispersion at 1.25 Gbps, 20 dB OSNR (0.1 Nm RBW)
Note:
When shorter distances of single-mode fiber are used, it might be necessary to insert an in-line optical attenuator in the link to avoid
overloading the receiver.
