Abstract :
We demonstrate Offset-QPSK transmitter and receiver architectures for 112 Gb/s coherent optical networks, highlighting similarities and differences to QPSK implementations. Experimentally we demonstrate that O-QPSK exhibits an enhanced immunity to nonlinearities when transmitted over TrueWave® fiber links.
