Análisis y simulación de la no linealidad de la fibra óptica en el rendimiento de la codificación de línea NRZ y RZ para enlaces de alta velocidad de transmisión.

Abstract

The issue is associated with linear coding and modulation in optical transmission channels in terms of ensuring maximum distance transmission and having a high Q factor, lower BER, with spectral characteristics and system energy budget, also considering the main limiting factors both in transition system and limitations of the dispersion and attenuation of the optical fiber, the non-linear effects and the number of amplifying sections. The comparison of the results of the simulation of the model performed is performed when transmitting coded line signals in RZ and NRZ of the fiber optic segment in the transmission of 10 Gbps with optical amplification sections, using the OptiSystem software with a length of the 100 km and 200 km fiber optic line. The signals are distributed through a single-mode optical fiber (SMF) and with optical amplification, taking into account the dispersion of the group's distribution speed, the auto-phase modulation (SPM), and the line losses and the periodic amplification when adding the noise of increased amplified spontaneous emission.
