5 × 5 25 Gbit/s WDM-MDM

Abstract

Wavelength-division multiplexed-passive optical network (WDM-PON) is a revolutionary high-capacity and scalable broadband access network. This paper capitalizes on Laguerre-Gaussian (LG) modes to reduce modal dispersion and increase data capacity. A data rate of 25 Gbit/s is attained for a multimode fiber link by multiplexing five LG modes on five wavelengths centered at 1,550.12 nm for a distance up to 800 m.

Effect of decision feedback equalizer taps on 3×6- channel mode-wavelength division multiplexing system performance in multimode fiber

“…MDM has been realized through through holographic wavefront generation [9][10][11][12], multi-core fibers [13][14][15], mode-selective fiber couplers [16][17][18], laser cavity design [19][20][21] or via optical signal processing [17,22,23].…”

Performance Evaluation of a 4 × 20-Gbps OFDM-Based FSO Link Incorporating Hybrid W-MDM Techniques

“…Z. Zhao et al reported an ultrahigh capacity FSO communication system over strong atmospheric turbulence conditions by incorporating hybridization of OAM multiplexing, polarization multiplexing, and frequency multiplexing [39]. The research works in references [40][41][42][43][44] report the simulative analysis of MDM-based high-capacity radio over fiber (RoF) links.…”

Mitigation of Atmospheric Turbulences Using Mode Division Multiplexing based on Decision Feedback Equalizer for Free Space Optics

“…Furthermore, the FSO guarantees increasing the capacity by using mode division multiplexing (MDM) technology. MDM is a promising technology [9][10][11] used to transmit the optical signal or light beams in form of modes such as Laguerre-Gaussian mode [12,13], Hermite-Gaussian (HG) mode [14,15], helical-phase mode [16,1718], spot mode, and donut mode [14,16,19] through the transmission channel that leads to expand the capacity . This technology has been used over optical fibre and FSO, where it successfully achieved increasing the data capacity.…”
