“…At the receiver side, a half-symbol spaced 12 × 12 multiple-input and multipleoutput (MIMO) equalizer was used for mode DEMUX regarding DMD dependency on the optical carrier frequencies of WDM channels. In the same manner, 10.16 Pb/s transmission was recently achieved [50].…”

SUMMARYThe potential transmission capacity of a standard single-mode fiber peaks at around 100 Tb/s owing to fiber nonlinearity and the bandwidth limitation of amplifiers. As the last frontier of multiplexing, space-division multiplexing (SDM) has been studied intensively in recent years. Although there is still time to deploy such a novel fiber communication infrastructure; basic research on SDM has been carried out. Therefore, a comprehensive review is worthwhile at this time toward further practical investigations.

“…O meet the ever-increasing demand for large-capacity optical fiber transmission, space-division multiplexing (SDM) based on single-mode multi-core fibers (SM-MCFs) or few-mode multi-core fibers (FM-MCFs) has been proposed to significantly increase the aggregated spectral efficiency and transmission capacity [1][2][3]. Compared system, the transmission system using SM-MCF with uncoupled cores has the advantage of being free from mode dependent loss and modal differential group delay, thus removing the need for computation-intensive multiple-input multiple-output (MIMO) processing and lowering both power consumption and latency.…”

“…A large-capacity WDM/SDM transmission system typically consists of thousands or tens of thousands of parallel channels in both wavelength and space [1][2][3][4][5]8] domains, which usually do not exhibit the same transmission performance due to unequal gain of optical amplifier over wavelengths, loss variation of spatial channels and power variation among all the channels. However, the overall transmission performance is usually limited by the worst channels, in order to achieve error-free performance for all the transmitted channels.…”

We demonstrate wavelength-division-multiplexed (WDM) and space-division-multiplexed (SDM) transmission of probabilistically shaped polarization-division-multiplexed (PDM) 1024-state quadrature amplitude modulation (QAM) channels over a 9.7-km single-mode 30-core fiber, achieving aggregated spectral efficiency of 297.82 bit/s/Hz on a 12.5-GHz grid and 7.01-Tbit/s spatial-super-channel on a 25-GHz grid without multipleinput multiple-output (MIMO) processing. Actual soft-decision forward error correction (SD-FEC) decoding was employed to obtain error-free performance, and adaptive rates and spectral efficiencies for individual WDM/SDM channels have been applied according to their channel conditions, by adjusting the SD-FEC overhead without changing the modulation format. Probabilistically shaped PDM-1024-QAM has been used to further increase the aggregated achievable rate due to the added performance improvement through shaping gain. Index Terms-Optical fiber communication, wavelength division multiplexing (WDM), space division multiplexing (SDM), spectral efficiency, adaptive rate, probabilistic shaping, forward error correction (FEC), 1024-state quadrature amplitude modulation (1024-QAM).

“…I NFORMATION-based technologies are driving a durable demand in terms of transmission capacity meaning that the limits of current optical networks could shortly be reached [1]. One promising approach to increase the capacity of optical fibers is the use the spatial diversity like Mode Division Multiplexing (MDM) in few-mode or multi-mode fibers (MMFs) [1], [2], [3]. Several multiplexing methods have already been proposed among which mode selective photonic lanterns [4], [5].…”

Space Division Multiplexing (SMD) is a very attractive technique for addressing the ever-growing demands in transmission capacity by enabling the use of a new parameter -space -to increase the number of channels in multi-mode fibers. One key component to build a spatially multiplexed-based optical network is a spatial multiplexer and demultiplexer combining signals from multiple single-mode fibers into as many channels in a multi-mode fiber. In this article, we report the fabrication and characterization of a pair of 45-mode spatial multiplexer and demultiplexer saturating all the modes of a standard 50 µm core graded-index (OM2) multi-mode fiber. The multiplexers are based on Multi-Plane Light Conversion (MPLC), a technique that enables the control of the transverse shape of the light by multiple reflections on specifically designed phase plates. We show that by using a separable variable basis of modes, such as Hermite-Gaussian (HG) modes, we are able to drastically reduce the number of reflections hence reducing the insertion losses and modal crosstalks. The multiplexers typically show an average 4 dB insertion loss and -28 dB cross-talk across the C band. Finally, we emphasize the use of this higher-order modes multiplexer to explore the propagation properties inside multi-mode fibers and more specifically the mode group crosstalks as well as the impact of fiber bending.
