TL;DR: In this article, the authors investigate high capacity few-mode fiber transmission for short and medium-haul optical links and demonstrate C + L band transmission of 283 Tbit/s over a single 30 km span and recirculating loop transmission of 159 Tbit /s over 1045 km graded-index three mode fiber.

Mode coupling at connectors in mode-division multiplexed transmission over few-mode fiber
Jordi Vuong,Petros Ramantanis,Yann Frignac,Massimiliano Salsi,Philippe Genevaux,Djalal Falih Bendimerad,Gabriel Charlet +6 more
TL;DR: This work analytically derive the coupling matrix of the multimode connector and numerically study the dependence of the matrix coefficients as a function of the butt-joint connection characteristics to assess the impact of the connector on the signal quality investigating different receiver digital signal processing (DSP) schemes.

Nonlinear interaction in differential mode delay managed mode-division multiplexed transmission systems.
TL;DR: It is found out that DMD Management can lead to a degraded performance, due to enhanced intermodal nonlinear interaction, similar to the effects that show up in dispersion managed single-mode systems.

Splice loss requirements in multi-mode fiber mode-division-multiplex transmission links.
Stefan Warm,Klaus Petermann +1 more
TL;DR: This work investigates numerically the influence of fiber splices and fiber connectors to the statistics of mode dependent loss (MDL) and multiple-input multiple-output (MIMO) outage capacity in mode multiplexed multi-mode fiber links and shows that discrete mode permutation (mixing) within the transmission line may effectively increase the maximum transmission distance.

Modeling of Mode Coupling in Multimode Fibers With Respect to Bandwidth and Loss
TL;DR: In this article, a fast, accurate and simple field coupling model is presented which is capable of describing mode coupling effects due to bends and splices in multimode fibers with parabolic index profile as well as the coupling losses induced by this process.

Assessing the Effects of Mode-Dependent Loss in Space-Division Multiplexed Systems
TL;DR: The figure of merit that is presented for quantifying MDL incorporates the effect on the transmitted signal and the noise and is directly related to the spectral efficiency reduction.

Equalizer tap length requirement for mode group delay-compensated fiber link with weakly random mode coupling.
Neng Bai,Guifang Li +1 more
TL;DR: The result reveals that under weak random mode coupling, the required tap length of the equalizer is proportional to modal group delay of a single DMGD compensated pair, instead of the total modalGroup delay of the entire link.

Differential mode delay management in spliced multimode fiber transmission systems
TL;DR: It is shown that DMD managed links, even with significant mode coupling due to splices, strongly reduce the link DMD.
