Versatile in-line transceiver chip operating in two full-duplex modes at 1.3 and 1.55 μm

We describe a transceiver chip which can perform full-duplex operation alternatively in the 1.3 μm (TX)/1.5 μm (RX) or 1.5 μm (TX)/1.3 μm (RX) mode. A full duplex sensitivity of -28.4 dBm is reported for the transceiver mode emitting at 1.55 μm and receiving at 1.3 μm.
