Abstract: 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.

Abstract: An optical communication system comprises N server racks, first and second distribution frames, and first and second optical fiber cables. Each of the first and second optical fiber cables has N optical connector groups for racks and an optical connector group for distribution frame including M optical connectors. The closer the number of an optical connector of the M optical connectors is to the last number, the longer a wiring distance from the optical connector group for distribution frame to a corresponding optical connector group of the N optical connector groups for racks in the first optical fiber cable. The closer the number of an optical connector of the M optical connectors is to the last number, the shorter a wiring distance from the optical connector group for distribution frame to a corresponding optical connector group of the N optical connector groups for racks in the second optical fiber cable.

Abstract: An optical fiber cable includes an optical fiber bundle including optical fibers and a protective member having a cylindrical shape and defining an internal space where the optical fiber bundle is accommodated. The optical fiber bundle being a single optical fiber bundle is accommodated in the internal space. The protective member includes a first cylindrical portion having a ring-shaped first cut and a second cylindrical portion having a second cut corresponding to the first cut, the second cylindrical portion being spaced from the first cylindrical portion. An end of a first optical fiber included in the optical fibers is pulled out to outside of the protective member from between the first cylindrical portion and the second cylindrical portion.

Abstract: An optical connector is disclosed. The optical connector includes a rear housing, an inner housing, and an outer housing. The inner housing includes a retaining hole to accommodate a ferrule. The outer housing is disposed on an outer periphery of the inner housing to cover a front portion of the inner housing. The outer housing rotates about the central axis with respect to the inner housing by a rotation guiding mechanism cooperating with an adapter for connecting the optical connector to another optical connector. The outer housing includes a front wall covering the distal end of the inner housing. The front wall includes at least one opening region. The opening region corresponds to a fiber exposed surface of the ferrule when the outer housing is rotated with respect to the inner housing from an initial position to a connected position by the rotation guiding mechanism.
