Researchers in Japan have demonstrated the possibility of combining highly spectral efficient wideband optical transmission with an optical fiber guiding 15 fiber modes that had a cladding diameter in agreement with the current industry standard of 0.125 mm. This was enabled by mode multiplexers and an optical fiber that supported wideband transmission of more than 80 nm over 23 km. The study highlights the large potential of single-core multi-mode fibers for high-capacity transmission using fiber manufacturing processes like those used in the production of standard multi-mode fibers. The results of this study were accepted for the post-deadline session at the 46th European Conference on Optical Communication (ECOC 2020)…read more.
