Abstract: An optical connector includes a connector housing; an optical ferrule that is housed in the connector housing; a coil spring that is housed in the connector housing and impresses the optical ferrule in a forward direction; and a spring pressing portion that is attached to an rear end of the connector housing, has an optical fiber inserting through-hole and a spring reception portion, and receives a reaction force of the coil spring.

Abstract: A method and system connects multiple cores within one fiber, e.g., a multi-core fiber (MCF), to multiple fibers with single-cores. The single-core fibers can then be terminated by traditional envelopes, such as a single core LC envelope.

One or more of the single core fibers may be terminated along the length of the jumper to form a jumper with one or more tap accesses.

Abstract: An optical connector having an optical fiber inserted into a connector main body includes a buckling regulating section whose length in an optical fiber insertion direction is formed variable and which regulates a buckling of the optical fiber while becoming short in an optical fiber insertion direction when the optical fiber is inserted into the connector main body.
