Aspects of connecting the single-core and multi-core optical fibers

Abstract

The paper presents the phenomena, that occur during the coupling of the cores included in the multi-core fibers (MCFs). It presents the design parameters of MCF, which have a major impact on their connection with each other and with the single-core single-mode optical fiber (SC-SMF), shortly called SMF. It has been demonstrated the need to constitute a new standard for multi-core fibers to the their mass coupling was simple and cheap. An analysis of use of fixed and reconnected techniques of the MCF and SMF coupling, have been presented. Attention was paid to the elements that affecting the quality of the MCF-to-MCF and MCF-to-SMF coupling, especially during fusion splicing. It presented the latest technologies used for connecting the optical fibers of new generation and proposes of new solutions and modifications, that can improve the work of future optical fiber fusion splicers.
