This paper describes researches concerning the use of Wavelength-Division Multiplexing (WDM) techniques over Polymer Optical Fibres (POFs) links for Residential Networks applications. It is reported the development of a 2-channel WDM Multiplexer/Demultiplexer (MUX/DEMUX) device based on a commercially available dichroic beam-splitter operating in the visible spectra. It describes the use of the...

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 returnto-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 ...

Abstrak – The effect of dispersion of fiber on the performance of OCDMA system and to find the limitations imposed by dispersion on number of user and length of transmission. It has been observed that in the bit error rate performance curve the error is decreased when the number of subscriber is increased side by side the optical power is reduced when the users is added. This paper has presente...
