Paper Abstract

This paper describes the transmission performance of the 10Gb/s phase-modulated (PM) duobinary modulation format, compared with the conventional duobinary modulation format using a low-pass filter (LPF) in cascaded optical networks. We theoretically investigate the transmission characteristics of both modulation formats with considering the effect of narrowing bandwidth of multiplexers (MUX) and demultiplexers (DEMUX) at cascaded nodes with different fiber launching powers (FLP). It's shown that PM duobinary signals, at the FLP of 9dBm, can be transmitted over 3 nodes (up to a distance of 1,200km) with only 1.25dB power penalty.
