Analysis of Attenuation Compensation Using Erbium Doped Fiber Amplifiers on Wavelength Division Multiplexing Networks as Optical Amplifiers in Communication Systems

Abstract

Abstract Communication technology is currently very rapidly growing that causes the need for data flow speed increase significantly. These needs could be met through the technology of a fiber optic. The addition of use wavelength division multiplexing (WDM) networks can increase the bandwidth value because this network system can enter several wavelengths in a block diagram that is a multiplexer. This paper will discuss concerning a WDM that uses optical amplifier EDFA to strengthen a transmitted signal with input signal is sent two channel in one axis a fiber optic. Approach was used in the study simulations with three types of variation. The results of the simulation showed the variations of this type of circuit, the circuit is a form of consumption preline most excellent attenuation coefficient has 0.593 dBm/km, the variation of the value of the bandwidth on the value of 200 GHz is the value that best has a attenuation coefficient dBm 0.026/km and variations of long fiber optics at a distance 1 km that is the distance transmission of maximum.
