A first optical fiber line of the pair of optical fiber lines includes a first end and a second end, a second optical fiber line of the pair of optical fiber lines includes a third end and a fourth end, the one or plurality of connection members optically connect the second end to the fourth end, the light source causes testing light to be incident on the first end, and the first power meter measures first intensity of first output light output from the third end by causing the testing light to propagate through the pair of optical fiber lines.

Measurement system

In a fiber connection structure with optical connectors according to one embodiment, among m first connector port groups, arrangement orders of colors of a plurality of the optical fibers in (2×j−1)th (j is a natural number satisfying 1≤j and 2×j≤m) first connector port groups are the same, and among the m first connector port groups, arrangement orders of the colors of the plurality of optical fibers in (2×j)th first connector port groups are the same. The arrangement order of the colors of the plurality of optical fibers in the (2×j)th first connector port group is a reverse order of the arrangement order of the colors of the plurality of optical fibers in the (2×j−1)th first connector port group.

Fiber connection structure with optical connector, and module

An optical connector-equipped fiber connection structure according to an embodiment includes at least three groups including two or more optical fibers adjacent to each other. In the groups, two or more of the optical fibers extend from a first multi-core connector to a second multi-core connector without intersecting with each other. Optical fibers of two groups in the at least three groups intersect with each other in a midway point going from the first multi-core connector to the second multi-core connector. Optical fibers of groups other than the two groups extend from the first multi-core connector to the second multi-core connector without intersecting with the other optical fibers extending from the first multi-core connector.

Fiber connection structure provided with optical connector, module, and assembly
