Quadrature Amplitude Modulation All Optical Orthogonal Frequency Division Multiplexing-dense Wavelength Division Multiplexing-optical Wireless Communication System under Different Weather Conditions

This paper proposes an analytical model for evaluating the performance of dense wavelength division multiplexing (DWDM) for all optical orthogonal frequency division multiplexing (AO-OFDM) optical wireless channel. The investigated performance for proposed system is evaluated for the parameters  bit error rate (BER) and Q factor .The constellation diagrams, and bit error rate (BER) of the recei...

Simulation and Analysis the Performance of 3970 Km DWDM Transmission Link Employing Optimized Semiconductor Optical Amplifiers

In this paper first we try to analysis the behavior ofthe SOAs in the optical networks and then have proposed anumerical simple model to simulate the behavior of thesemiconductor optical amplifiers. After that by employing thismodel as inline amplifier for a DWDM optical system, we havesimulated the transmission of 10 channels with bit rate 10 Gb/sup to distance 3970 km with RZ-DPSK modulation ...
