MULTICORE/MULTIMODE FIBER JOINING DEVICE

摘要

[Problem] A device for joining a multicore/multimode fiber that can transmit a large quantity of information. [Solution] This multicore/multimode fiber joining device has a first fiber group (11), a first light gathering system (13), a first mode converter (15), a second fiber group (21), a second light gathering system (23), and light gathering system (33) for multicore fibers. By means of the first mode converter (15), light from the first fiber group (11) is subjected to mode conversion en masse. A space joining system (33) for multicore fibers transmits light derived from the second fiber group (21) and light derived from the first fiber group (11) subjected to mode conversion to the multicore fibers (31).
