เทคนิคการจัดระยะห่างช่องสัญญาณแบบ RAUS ในระบบส่งสัญญาณ DWDM

Abstract

This paper presents the repeated alternate unequally spaced (RAUS) to improve the effect of FWM due to the fibers nonlinear. We proposed a new method to spaced channel allocation of ITU-T G.469.1 standard. By developing a technique of repeated unequally spaced (RUS). This system, we consider the generate wavelength of erbium dope fiber amplifier (EDFA) between 1529.55 – 1560.61nm for DWDM signals. From the simulation results, It found that the new proposed method RAUS is the better performance of the efficiency of four-wave mixing (FWM) lights ( ) by comparing the proposed method with RUS algorithm. The new proposed method can be improved the error probability and decreases the FWM light power in DWDM transmission systems.
