Abstract
This paper proposes the new technique to improve the conventional techniques in the channel allocations, in order to reduce transmission loss, in case of there are a large number of channel and each of channel is nearby. We have found this case in Dense Wavelength Division Multiplexing (DWDM) that is the cause of transmission loss called Four-Wave Mixing due to the fiber nonlinear. The channel allocations that used to resolve this problem are Equally Spaced (ES), Unequally Spaced (US), Repeated Alternate US (RAUS). This paper present the new technique to arrange the channel allocation in called paired URAUS to avoid the four-wave mixing. From the simulation results, the new proposed technique has lower the effect of Four-Wave Mixing than the conventional techniques and decrease bit error probabilities and bandwidth, containing higher channels, in DWDM transmission systems.
