“…The calculated results for these parameters, using the equations (11)- (13), for the case when we use GI-MMF (50/125 m), provide two possible injection conditions: First one is when w 1 ¼ 7 m, F 1 ¼ 0 m for wavelength 1 ¼ 850 nm, and a second one when w 1 ¼ 3 m, F 1 ¼ 0 m for wavelength 1 ¼ 1550 nm. For the case of when we use GI-MMF (62.5/125 m), there are two possible injection conditions; the first one is when w 1 ¼ 3 m, F 1 ¼ 0 m for wavelength 1 ¼ 1550 nm, and a second one is when…”

In current local area networks, multimode fibers (MMFs), primarily graded index\ud (GI) MMFs, are the main types of fibers employed for data communications. Due to\ud their enormous bandwidth, it is considered that they are the main channel medium that\ud can offer broadband multiservices using optical multiplexing techniques. Amongst\ud these, mode group diversity multiplexing (MGDM) has been proposed as a way to integrate\ud various services over an MMF network by exciting different groups of modes that\ud can be used as independent and parallel communication channels. In this paper, we\ud study optical multiple-input–multiple-output (O-MIMO) systems using MGDM techniques\ud while also optimizing the launching conditions of light at the fiber inputs and the spot\ud size, radial offset, angular offset, wavelength, and the radii of the segment areas of the\ud detectors. We propose a new approach based on the optimization of launching and detection\ud conditions in order to increase the capacity of an O-MIMO link using the MGDM\ud technique. We propose a (3 3) O-MIMO system, where our simulation results show\ud significant improvement in GI MMFs' capacity compared with existing O-MIMO\ud systems

“…Intramode coupling effect do not contribute significantly due to MGDM, so it can be ignored. However, inter-mode coupling always has a detrimental effect as compared to intra-mode coupling which obviously degrades the signal quality [39]. We observed around 1.2 dB penalty, after introducing crosstalk while keeping all other simulation parameters same, as shown in Fig.…”

In this paper, we propose a full duplex architecture based on a hybrid link composed of free space optics (FSO) and multimode plastic optical fiber (MMPOF) for short-range wireless access networks. The proposed architecture employs mode group division multiplexing (MGDM) and wavelength reuse techniques to transmit data between central unit (CU) and radio access units (RAUs). An optical frequency comb source to generate multiple optical sidebands is realized using a single laser source to provide 60 GHz millimeter-wave (mm-wave) signals at each RAU by simultaneously transmitting PAM-4 signal on linearly polarized (LP) modes of each optical sideband. Data rate of 2$$\times$$ × 12 Gbps at mm-wave frequency of 60 GHz is achieved for both downlink (DL) and uplink (UL) transmissions. The transmission of 2$$\times$$ × 12 Gbps PAM-4 signal over hybrid FSO-MMPOF link is investigated at different values of refractive index structure parameter ($$C_n^2$$ C n 2 ) by employing log-normal (LN) FSO channel model to support three RAUs in a ring topology. The acceptable receiver sensitivities below −5 and −0.6 dBm for DL and UL transmissions are achieved, respectively. The proposed hybrid architecture can be a potential candidate for future communication networks.

Mode Group Diversity Multiplexing (MGDM) is an Optical Multiple-Input-Multiple-Output (O-MIMO) technique that provides larger robustness and capacity for data communication over MultiMode Fiber (MMF). The utility of a MGDM system in terms of capacity expansion gives a major interest in most applications of optical communication. In this paper, we propose a transfer matrix decompositioon of O-MIMO systems using MGDM technique in order to increase the capacity of the system. This treatment can be divided into 3 stages: noise whitening, channel diagonalization and dimension reduction. Numerical Matlab simulations results of a 3×3 MGDM link are given to support the efficiency of this study.
