Abstract
We analyze the transmission performance of vestigial sideband (VSB) signals with electrical dispersion compensator (EDC) by numerical simulations. Optimizing the dispersion and bandwidth of EDC, and the extinction ratio and chirp of the modulator, we can improve the dispersion tolerance of VSB signals. VSB signals with negative chirp have better transmission performance while VSB signals with positive chirp are advantageous to the implementation of EDC due to low optimum dispersion in EDC. VSB transmission with EDC can be a very cost-effective solution for 10-Gb/s single-channel systems with the maximum transmission distance of 320 km.
