Two fiber-bundle-typed fan-in/fan-out (FI/FO) devices, “wavy hexagon-shaped silhouette” type (W-FI/FO) and “tortoise-shaped silhouette” type (T-FI/FO), have been proposed and manufactured based on tapering glass tubes for docking with a self-made 13-core 5-mode fiber. The W-FI/FO device consists of 19 5-mode fibers and has an extended layout based on the 13-core 5-mode fiber structure. It could dock multiple fibers with 19 or 13 cores of the same size standards.
