Study of Optical MIMO Transmission Systems Using the MGDM Multiplexing Technique

Abstract

In current local area networks, multimode fibers (MMFs), mainly graded index (GI) MMFs, are the main types of fibers used for data communications. Because of their high bandwidth, they are considered the main method of transmission that allows to offer multiservice broadband services using optical multiplexing techniques.
 
 The MGDM (ModeGroup Division Multiplexing) is a Multiplexing technique, which aims to improve the performance of the multimode optical fiber by spatially multiplexing the data streams to be transmitted. In this work, we study optical MIMO (multi-input multi-output) transmission systems on an MMF optical fiber, specifically the adaptation of the architecture of MIMO transmission systems. In this context, we have studied the mode group multiplexing technique (MDGM), to evaluate the transmission capacity. In fact, the latter depends on the injection conditions and the state of the optical fiber.

Studying the effect of changing Input conditions on MMF using MGDM technique

“…It was obtained higher bandwidth in high speed railway HSR communications as well as improving the signal transmitted quality. In the last method, it is used MGDM technique as studied in [15]. This work is found the transmission capacity by using 2x2 MGDM technique through changing the injection parameters in the MMF optical fiber and using MIMO systems.…”
