Study of the Valuation of Multimode Optical Fibers by Translation of Transmission Techniques of Optical Fiber and High Speed Mimo Radio Frequency in Local Area Network.

Abstract

— In this paper, we focused on making a study of the valuation of multimode optical fiber which is used a lot in local networks and yet that we talk less in this last decade which knows an increase of new technologies using an enormous speed. To do so, we made a translation between radio frequency MIMO and optical MIMO; a study which has already been carried out in a framework of comparison of two technologies and in the literature, this convergence is already possible. Note that this is done in terms of transfer functions and of which we have made a very explicit analytical study compared to other studies already carried out in the literature for an educational and didactic objective for future studies in this context. Then we focused on doing our valuation study of multimode optical fiber, through optical MIMO technology, and our thinking was based on the quality of the signal at reception, for this, a study of modulation formats was made, because with the rise of technologies, this of course leads to an increase in speeds, so that certain formats tend to almost total disappearance. During this study, the RZ (Return to zero) format is much better in a larger local network, in terms of its Q factor and NRZ (None Return to Zero), for a smaller network, depending on its bit error rate (BER) and their eye diagrams which have a very large aperture and this is extended for the RZ format.
