Abstract
Abstract A multicore optical fiber (1,1) with optical connectors (11) in which the optical connectors are attached to the ends of a plurality of parallel optical fibers (2): projections (13) are formed on the end faces of the optical connectors (11) to expose the end faces of the optical fibers (2) at the ends of these projections, and an optical connector opposing guide (15,16) is provided at the end faces of the optical connectors apart from the projections (13). Thus, the end faces of the opposed projections (13) are smaller in area than the end faces of the optical connectors, and accurate alignment can be achieved together with sufficient force of the projections against each other.
