“…Few Mode Fibers (FMFs)), allows parallel transmission channels defined by the different propagation modes [17]. However, mode coupling for long-haul transmission systems becomes inevitable in MMFs, and multi-input-multiple-output (MIMO) processing is necessary to decouple the signals.…”

“…This also leads to a considerable increase in system complexity [18], as well as significant extra power consumption and cost, which need to be offset by savings elsewhere in the system to make the approach commercially viable. Furthermore, mode-dependent losses and gain cannot be fully compensated [17]. The FMF approach also requires the development of coupling components, such as photonic lanterns, to launch different modes, or at least orthogonal groups of modes, into the core [19,20].…”

Multi-Element Fiber Technology for Space-Division Multiplexing Applications

et al. 2014

A novel technological approach to space division multiplexing (SDM) based on the use of multiple individual fibers embedded in a common polymer coating material is presented, which is referred to as Multi-Element Fiber (MEF). The approach ensures ultralow crosstalk between spatial channels and allows for cost-effective ways of realizing multi-spatial channel amplification and signal multiplexing/demultiplexing. Both the fabrication and characterization of a passive 3-element MEF for data transmission, and an active 5-element erbium/ytterbium doped MEF for cladding-pumped optical amplification that uses one of the elements as an integrated pump delivery fiber is reported. Finally, both components were combined to emulate an optical fiber network comprising SDM transmission lines and amplifiers, and illustrate the compatibility of the approach with existing installed single-mode WDM fiber systems.

“…Inspired by [11], we choose α = 0.2 dB/km, β ′′ = 20 ps/nm/km and γ · κ = 0.663 (km·W) −1 . At the receiver, signals are demultiplexed by wavelength and spatial mode, and ideal DP homodyne coherent detection is applied for each spatial mode.…”

We explore high-dimensional modulation for mode-division multiplexed optical fiber communication systems, focusing on optimized 24-D modulation formats in six-mode fiber transmission. Compared with conventional formats, our simulations demonstrate up to 8.7 dB span loss budget improvement for 6 b/s/Hz intra-channel spectral efficiency.

Multi-element fiber for space-division multiplexing

Abstract.A novel approach of using multi-element fiber (MEF) technology in space-division multiplexing (SDM) systems is presented. This paper reviews the progress in fabrication and characterization of MEF based both ultralow crosstalk transmission and amplifier fibers. Passive 3-element MEFs have been successfully demonstrated for application in telecommunications. An active 5-element MEF amplifier has also been demonstrated in a novel multiport cladding-pumped configuration, in which a central un-doped multi-mode pump fiber-element is surrounded by four Er/Yb-doped active fiber-elements. MEF is compatible with current WDM systems, and there is no need to develop specialized multiplexing/demultiplexing components. Moreover, it offers a smooth upgrade to SDM systems.
