Abstract

In this paper, the performance analysis in terms of receiver sensitivity is presented by comparing three recent electrical based multiplexing techniques; Multi Slot Amplitude Coding (MSAC), Duty Cycle Division Multiplexing (DCDM) and 4-Pulse Amplitude Modulation (4-PAM). A 30 Gbit/s back-to-back configuration of the optical receiver model with optical pre-amplifier for these techniques have been investigated by considering an optical amplifier and receiver noise. The results show that MSAC technique achieves significantly better receiver sensitivity compared to DCDM and 4-PAM. As an alternative electrical multiplexing technique, we believe that MSAC has good potential to be adopted in future cost sensitive applications of optical communication system.
