FEATURES OF OPTICAL SIGNALS SWITCHING AT USING DIFFERENT MODES OF INFORMATION TRANSFER

The analysis of optical signals switching with electrical and optical control and requirements for switching systems that provide increased bandwidth telecommunication network is presented in the paper. The model and methods of implementing all-optical switching, which do not use electro-optical and optoelectronic conversion of the information signal and do not require buffering of op-tical signals in all-optical switching device are considered. The feasibility of using different modes of information transfer for switching optical signals has been estimated. The benefits and limitations of the label and position multiplexing methods are shown. A model of optical network with all-optical switching blocks of information has been described. The block mode of information transfer usage expediency for the assigned task is proved.
