Paper Abstract

The first 8 Gb/s coherent optical detection system using two closely spaced subcarriers with 4 Gb/s QPSK on each subcarrier while maintaining an RF bandwidth efficiency of 1 bit/sec/Hz is reported. The receiver sensitivity is -26.5 dBm, with less than 0.5 dB penalty due to the other channel. It is expected that these techniques can be extended to transmit 16 Gb/s while using only 2 Gb/s baseband electronics.
