Full-duplex performance assessment of in-line transceivers emitting at 1.3 μm and receiving at 1.55 μm

Starting from the signal-to-noise ratio formula for in-line transceivers, we evaluate the receiver performance in full-duplex operation. We show theoretically and experimentally two methods to obtain a system compatible sensitivity. Full-duplex sensitivities of -23.9 dBm and -19.1 dBm are demonstrated at 68 Mb/s and 196 Mb/s, respectively.
