“…The exponential increase of data traffic in FTTH has inspired researchers across the world to explore various multiplexing techniques within access networks to increase its capacity and transmission distance. Most of the multiplexing schemes for access networks are based on time division multiplexer (TDM) access [9], wavelength division multiplexer (WDM) access [10] have been used besides frequency division multiplexer (OFDM) access [11] and optical code division multiple (OCDM) access [5]. Mode division multiplexer (MDM) is a new scheme that has attracted remarkable attention as an innovative technology which increases the data rate [6,7,12].…”

In this paper, we design and investigate 10-channels of mode division multiplexer (MDM) over hybrid free-space optics (FSO) link in several weather conditions to achieve the maximum possible medium range and fiber to the home (FTTH) for high bandwidth access networks. System capacity can be effectively increased with the use of MDM over hybrid FSO-FTTH. In this study, a 10-channel MDM over FSO-FTTH system has been analyzed in different weather conditions that operate at 1550 nm wavelength. The simulated system has transmitted 100 Gbit/s up for a distance of 3200 meters FSO in superbly clear weather condition. It also transmitted 100 Gbit/s up for a distance of 650 meters FSO during heavy rain. The validation of this study is measures based on eye diagrams bit-error rates (BER) that have been analyzed.

Fi-Wi networks, emblematic of the convergence between optical fibers and wireless access, stand resolutely at the vanguard of the transformative redefinition of communication paradigms. As advanced communication networks persistently redefine the contours of connectivity, characterized by their unparalleled speed, minimal latency, and augmented capacity, the exigency for innovative approaches undergoes heightened intensification. The crux of this study pivots upon the methodical application of multiplexing techniques, notably wavelength division multiplexing (WDM), optical code division multiplexing (OCDMA), and optical time division multiplexing (OTDM), each deployed with precision to elevate the nuanced performance of the Fi-Wi network. The multifaceted optimization of these techniques not only imparts an impetus to data transfer rates, mitigates latency, and augments spectral efficiency but concurrently instigates the realm of wireless connectivity. The research undertakes a technical exploration of the deployed multiplexing strategies, delineating their idiosyncratic advantages. A discerning comparative analysis vis-a-vis the hybrid (Fi-Wi)-single model, precisely serving as the baseline, unequivocally delineates the superior performance of the proposed methods across metrics of Q-factor, eye height, and logarithmic bit error rate-Q factor.
