Fusion Splicing Achieves Low Loss in Spacing-Mismatched Multicore Fibers
FUDAN, China, Feb. 14, 2022 — Researchers at Fudan University demonstrated low-loss fusion splicing techniques between spacing-mismatched multicore fibers (MCFs). According to the researchers, the work builds on previous studies — including from other research groups — that addressed the challenge of multicore splicing but did not address MCF splicing with any mismatched spacings. Multicore fibers offer numerous advantages over single-core design, in transmission capacity, space saving integration,
