The carriers’ need for bandwidth in metro and core optical networks is ever-increasing. This is due to the growing demand for high-speed data services, Internet video services, data centers, higher-bandwidth residential broadband connections and wireless backhaul deployments. For several years now, the optical transport industry has been developing 100G technology, for example 100G transponders and muxponders, which are based on single-carrier DP-QPSK modulation and coherent detection, for the purpose of providing additional network capacity, improving spectral effi ciency and lowering the cost per bit.
