TL;DR: In this article, the authors present a numerical simulation of the impact of alien wavelength bandwidth on optical transmission quality, and they conclude that alien bandwidth bandwidth must be restricted and that the result of this is an unforeseeable impact of the alien wavelength parameters on friendly wavelengths quality.

TL;DR: This article describes the issues related to the analysis of the reliability-exploitation of power supply systems in transport telematics devices (PSSs in TTDs), and addresses the issue of determining CQoPS factor.

TL;DR: A simple analytical expression based on E-model is applied to analyse the impact of packet loss and delay on voice transmission quality and the relationship between overall transmission quality rating, packet Loss and delay G.711, G.730 and G.729 codecs is presented.

TL;DR: A method for strain discrimination based on monitoring of the cavity length is proposed, enabling potential multiplexation of the sensor of two structures, which have the similar reflection spectra, by means of their spectral position.

TL;DR: In this paper, a simple method of the calculation of spatial distribution of birefringence in an optical-fiber link is presented, based on an analysis of the properties of the backscattered optical signal.
