Output Signal Power Analysis in Erbium-Doped Fiber Amplifier with Pump Power and Length Variation Using Various Pumping Techniques

Abstract

The scope of this paper is to analyze the output signal power with pump power and length variation in cascaded EDFA simulation model performance. This paper describes the simulation model of Erbium-Doped Fiber Amplifier (EDFA) of variable lengths (10 m, 50 m, and 120 m) with dual pumping techniques (dual forward pumping with two 980 nm wavelengths, dual forward and backward pumping with two 980 nm wavelengths) and Tri-pumping techniques. The simulation models consist of input source and pump power coupled by WDM coupler which gives optimized signal power in the above-mentioned simulation model. The simulation model consists of source with multiple wavelengths (1520 nm–1618 nm), pumping source with the wavelength 980 nm, isolator, and filter. The resulting models accurately represent EDFA optimized output signal power. Simulation results show that choosing careful fiber length 120 m and pump power 1 W in dual pumping provided 0.07 W optimized output signal power compared to other pumping techniques.

Protection Scheme for a Wavelength-Division-Multiplexed Passive Optical Network Based on Reconfigurable Optical Amplifiers

“…During the simulation, we model the EDFA using a built-in rate equation in VPI 8.5 in order to realize the optimum design of the bidirectional EDFA in ROA 3 . Many simulations on the performance analysis of an EDFA have been reported [18,20,21], based on which we determine the main parameters for the simulation. The parameters are shown in Table 3.…”

Realization of a Long-haul Optical Link with Erbium Doped Fiber Amplifier

“…The main function of optical isolator is to suppress laser oscillations and thus prevent feedback. At the EDFAs output, there is a narrowband optical filter that prevents spontaneous emission of the amplifier [9], [10][11][12][13]. The structure of EDFA in forward pump configuration is shown in Fig.…”

Chromatic Dispersion Compensation Effect Performance Enhancements Using FBG and EDFA-Wavelength Division Multiplexing Optical Transmission System

“…Besides, there are several types of amplifiers such as SOA, EDFA, and Raman amplifier that have been introduced to encounter the attenuation effects. However, EDFA still provide better results [7][8][9]. In this paper, we propose a new model to treat chromatic dispersion and signal attenuation.…”

“…Then, we compare the transmission system under study using the optimized setting parameters with a previous model proposed by other authors having chirped FBG as dispersion compensator [4][5][6][7] in terms of output power (dBm), noise figure (dB), gain (dB), -Factor, and eye diagrams at the received signal. In third section, we apply our model in four optical channels multiplexing with different wavelengths using an EDFA-WDM optical transmission system [9][10][11]. Finally, we apply and compare with a previous work using the WDM technology to prove more and more the efficiency of our model [12].…”
