"using only a single optical fiber... multi-band-compatible MIMO receiver combining multi-band WDM and SDM with large spatial channel count fibers (e.g., 114 channels with a 38-core 3-mode fiber)... >1,000X data rate... uncoupled four-core MCF is suitable for early adaptation... further improvement of the telecommunication infrastructure using ultra-large-capacity optical fibers will be needed in the future, where the data traffic demand is expected to increase by 3 orders of magnitude (x1,000 times)"
