Performance analysis of distributed fiber Raman amplifiers employing higher order pumping schemes in optical transmission systems

Abstract

Performance of fiber Raman amplifier is explored with special emphasis on higher order pumping configurations for wavelength division multiplexed optical transmission systems. The amplification analysis is done in terms of equivalent noise figure (ENF), optical signal-to-noise ratio (OSNR), and double Rayleigh backscattering (DRBS) noise powers. The investigations reveal that at 36 dB on-off gain, ENF improvement of 1 dB (using second order pumping) and of 2 dB (using third order pumping configuration) can be achieved. On similar lines, by varying input optical power and fiber length, OSNR and DRBS are reported for the higher order of pumping configurations. Overall, the work presents improvements of about 1 dB in ENF and 0.03 dB in OSNR. These investigations are produced at lower input signal powers.

HUBBLE: an optical link management system for dense wavelength divisionmultiplexing networks

“…The work in [11] proposed a machine learning solutions for quality analysis for the links. The article in [12] studied the performance of raman amplifier in the DWDM transmission systems that can be extended to be used for fault management purposes. Similar to our analysis in this paper, the authors in [13] are proposing a Geographical Information System (GIS) based fiber optic monitoring system that can be used as a fault or degradation detection tool.…”
