Abstract: A device for coupling a multicore/multimode fiber that can transmit a large quantity of information. This multicore/multimode fiber coupling device has a first fiber group (11), a first light converging system (13), a first mode converter (15), a second fiber group (21), a second light converging system (23), and light converging 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 coupling 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).
