Abstract

We have investigated cost-effective and simple duobinary modulations with/without using low pass filters (LPF) for the conventional duobinary modulation. For the proposed schemes, the effects of the electrical bandwidth and the DC extinction ratio of Mach-Zehnder (MZ) modulators have been investigated for transmission performances. The calculated eye-diagrams and BER characteristics of the proposed schemes have similar characteristics at 160 km transmission, compared to the conventional duobinary scheme. To explain the transmission performance of the proposed schemes, the chirp characteristics have been compared. We have obtained a similar SPM tolerance between the proposed schemes and the conventional duobinary modulation scheme.
