摘要: An optical connection structure including first optical fibers, second optical fibers, a first optical connector, and a second optical connector is disclosed. The first optical connector is configured such that each of first distal end portions of the first optical fibers protrudes from a first front end surface to the outside when the first optical connector and the second optical connector are connected to each other. Each of the first distal end portions is inserted into a corresponding second fiber hole of the second optical connector. The second optical connector is configured such that each of second distal end portions of the second optical fibers is moved rearward inside second fiber holes due to each of the first distal end portions respectively inserted into the second fiber holes. The first optical fibers and the second optical fibers are optically coupled to each other inside the second fiber holes.
