Análisis comparativo de los amplificadores ópticos EDFA, RAMAN y SOA para determinar las mejores prestaciones en enlaces de larga distancia mediante software de simulación.

Abstract

Due to the lack of an updated comparative analysis between optical amplifiers for both single-channel and multi-channel applications to determine which amplifier offers the best performance in terms of reach and different wavelengths, a comparative study was proposed between the Erbium-Doped Fiber Amplifier (EDFA), Raman Amplifier, and Semiconductor Optical Amplifier (SOA) in long-distance links. The evaluation was carried out through 8 simulation scenarios implemented using Optisystem software. In each scenario, variations in optical fiber distances of 25 km, 50 km, and 100 km, as well as wavelength variations of 1550 nm and 1565 nm, were considered to analyze the performance of each optical amplifier. In the simulation, the parameters were extracted from datasheets. Through the simulation, gain values for the Erbium-Doped Fiber Amplifier (EDFA) in a single-channel system of 34.5337 dB, 29.2532 dB, 19.2277 dB, and amplification values of 10.1642 dB, 3.66633 dB, and -7.42632 dB corresponding to the different distances of the proposed analysis were obtained. For a multi-channel system with a Raman amplifier, gain values of 23.214024 dB, 20.399309 dB, 16.68725 dB, and amplification values of -0.924428 dB, -3.45366 dB, and -7.40306 dB corresponding to the different distances were obtained. In this context, it is concluded that the comparative analysis helps determine that the Erbium-Doped Fiber Amplifier (EDFA) shows greater efficiency in single-channel systems and their variants due to its higher amplification capacity and better gain. On the other hand, the Raman amplifier presents better efficiency in multi-channel systems by meeting the necessary amplification and gain requirements for such configurations.
