In this article for the communication via monomode optical fibres we describe the possibilities of dispersion effects reduction. Characteristics of microstructural fibres with honeycomb cladding are presented together with their advantages. Then the way of present optical data cabling employment is demonstrated for STM-256 optical communication. Modern communications require always higher bit rates and the present cabling is not ready for the arrival of new link standards. The infrastructure for high video signal transmission can serve as a sufficient example.
In this article we describe the fiber optics reflectometer that we are actually developing at our workplace. The device integrates some nonconventional technologies. Principles of integrated photonic technologies are explained here. Reflectometer will be deployed as a sensor for distributed sensing of physical fields along the optical fiber. Key details of device implementation are disclosed here according to fiber optics, electronics, and termodynamics. and Článok popisuje polarizačný optický vláknový reflektometer, ktorý je aktuálne vyvíjaný na pracovisku autora. Zariadenie integruje niekoľko nekonvenčných technológií, ktorých podstata je v článku vysvetlená. Reflektometer bude nasadený ako senzor pre distribuované snímanie fyzikálnych polí pozdĺž optického vlákna. V článku sú diskutované kľúčové detaily implementácie reflektometra z pohľadu vláknovej optiky, elektroniky a termodynamiky.
