Ever increasing demand for higher bandwidth and capacity requests more efficient multiplexing techniques. Recently, hybrid optical systems have been developed in order to expand the capacity of optical networks. In this paper a combination of duty-cycle division multiplexing (DCDM) and polarization division multiplexing (PDM) system is proposed for long haul communication. In the proposed system each PDM channel carries 2-channel DCDM where each user is operating at data rate of 10 Gb/s which forms 2 2 10 Gb/s optical system. Results show that the bit error rate of 10􀀀9 for worst user is achieved at received power per chip of 21.12 dBm and optical signal to noise ratio of 22.08. Furthermore, system analysis demonstrates that the proposed system can tolerate the 10 ps/nm dispersion without any need for compensation.
