Abstract

Coupling Device Between Two Optical Fibers The invention relates to a coupling device between two optical fibers (1, 2). The coupling device (3) comprises at least one modal adapter (4) and a guiding system (5). The guiding system (5) is configured to position itself or at least one of the two fibers (1, 2) such that light sent from one of the two fibers (1, 2) passes through at least one modal adapter (4) and then through the other of the two fibers (1, 2).
