1. A first optical connector comprising:
a plurality of first optical fibers each extending in a longitudinal direction;
a first front ferrule including a first front end surface and a plurality of first fiber holes opening on the first front end surface; and
a first rear ferrule holding the plurality of first optical fibers,
wherein the first front ferrule is able to relatively move in the longitudinal direction with respect to the first rear ferrule, and
wherein the first optical connector is configured such that each of first distal end portions of the plurality of first optical fibers protrudes from the first front end surface outside of the plurality of first fiber holes when the first optical connector is connected to a second optical connector.
