International audience; The optimization of multiplexing (MUX) and demultiplexing (DMUX) 3-dB filter bandwidths for the optical differential quadrature phase shift key (DQPSK) combined with the return-to-zero (RZ) and carrier-suppressed return to zero (CS-RZ) is performed. The study of different optical signals in the 40 Gb/s dense wavelength division multiplexing (DWDM) system, with high spectral efficiency, is shown to be achievable with different filter types for access network. Performances of MUX and DMUX with different filter bandwidth is analyzed to get the best system performance for 40 Gbs/s DWDM transmission system with high spectral efficiency. The limitations imposed by misalignment of filters are also discussed.
