摘要：
Coherent optical fiber communications for data rates of 100 Gbit/s and beyond have recently been studied extensively because high sensitivity of coherent receivers could extend the transmission distance. Spectrally efficient modulation techniques such as M-ary phase shift keying(PSK) can be employed for coherent optical links. The integration of mu lti-level modulation formats based on coherent technologies with wavelength-division multiplexed(WDM) systems is vital to meet the aggregate bandwidth demand. This paper reviews coherent quadrature PSK(QPSK) systems to scale the network capacity and maximum reach of coherent optical communication systems to accommodate traffic growth.
