摘要：
By varying simultaneously the bandwidths of electrical transmitter filter, multiplexer and demultiplexer, the system performance of several duobinary coding formats is optimized for 40 Gbit/s/channel ultra dense wavelength division multiplexing (UDWDM) system with 50 GHz of channel spacing after 4x80 km of transmission. It is shown that bandwidth-limited (BL) duobinary generation schemes with optimized electrical transmitter filter bandwidth can achieve a Q-factor improvement of 1.4 dB over BL-conventional duobinary coding schemes. Moreover, the optimized BL-duobinary format achieves a better UDWDM system performance than BL-phase-shaped binary transmission, for which a capacityxdistance record was demonstrated.
