Abstract

In this paper, the performance of return-to-zero/differential quadrature phase shift keying/polarization shift keying (RZ/DQPSK/PolSK) orthogonal modulation format is investigated in hybrid optical time division and wavelength division multiplexing (OTDM–WDM) technique to increase the spectral efficiency of the system. The error free performance is achieved over 140 km transmission with the acceptable bit error rate (~ 10−12). The original contribution of this paper is to propose a bandwidth efficient OTDM–WDM system that could be projected even in high speed scenario and expected to be more technical viable due to use of optical orthogonal modulation formats.
