Experimental investigations of mode group diversity multiplexing on multimode fibre

“…Thereby, signal 1 is launched into the fibre in center launch position. This includes that only a few low order modes (in the ideal case the lowest mode will carry the most of the energy) are excited [1,4]. Additionally, it was recently explored [1] that for this launch position the low order modes travel during the transmission over the MMF mostly in the inner region of the core (shown in fig.…”

“…Multimode fibre (MMF) is an attractive medium for broadband Local Area Networks (LANs) as well as for future in house networks due to cost efficient components and easy installation process compared to single mode fibre systems [1]. Recently, the general idea of using mode group multiplexing in MMF transmission links was presented [1,2] as a possible alternative to the wavelength division multiplexing method.…”

“…Recently, the general idea of using mode group multiplexing in MMF transmission links was presented [1,2] as a possible alternative to the wavelength division multiplexing method. Until now, a large research effort has been made to investigate necessary requirements for mode multiplexing at the transmitter side (e.g.…”

10.7 Gb/s Over 300 m GI-MMF Using a 2 × 2 MIMO System Based on Mode Group Diversity Multiplexing

“…Multimode fibre (MMF) is a very attractive transmission medium due to low cost components compared to single mode fibre (SMF) in broadband local area networks (LANs) [1]. However, MMF is characterized by a low bandwidth distance product compared to SMF due to its multi mode character which implies mode dispersion as main limiting transmission effect.…”

“…Thereby, the MGDM approach is characterized by a high potential to increase the data rate [3]. Until now, a large research effort has been made to investigate possible transmitter and receiver setups to realize MGDM in high speed transmission systems [1,4]. In this paper, we investigate the feasibility of a complete MGDM system using mode multiplexing at the transmitter and demultiplexing at the receiver side.…”
