A measurement system includes a measurement device including a light source, and a first power meter, and one or a plurality of connection members each configured to optically connect a pair of optical fiber lines of the plurality of optical fiber lines. 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

A termination unit includes: a plurality of first optical fibers fusion-connected to a multicore cable; a tray slidable in a first direction, the tray being provided on one end side of the termination unit in the first direction; and a plurality of adapters which are provided in a line on the tray, to which a plurality of second optical fibers are connected from each of one end sides of the adapters, and to which the plurality of first optical fibers are connected from each of the other end sides of the adapters, in which the tray has a cover part for protecting the plurality of adapters, and in which the cover part is rotatable with a shaft that extends along a second direction, and the cover part rotates downward when the tray has slid in a direction toward the one end side from the other end side.

Termination unit

An optical fiber rack includes: a rack part on which a plurality of termination units arranged along an up-down direction are located; an optical fiber housing part which has a back plate and in which an extra length wiring part in a plurality of optical fiber bundles connected to each of the plurality of termination units is housed; and a plurality of first dividing bodies for dividing locations of the optical fiber bundles in the optical fiber housing part, the plurality of first dividing bodies being attached to the back plate so as to be arranged along the up-down direction in the optical fiber housing part. The first dividing body has a holding part for holding the corresponding optical fiber bundle, and the holding part of the first dividing body provided lower in the up-down direction is positioned to be separated from the back plate.

Fiber optic cable rack

An optical connector according to an exemplary embodiment is an optical connector including a plurality of optical connector plugs collectively connected to each of a plurality of adapters arranged along a first direction and a second direction intersecting the first direction, along a connection direction intersecting both the first direction and the second direction, the optical connector includes: a plurality of holders configured to be arranged along the second direction while holding the plurality of optical connector plugs arranged in the first direction, and a handle configured to hold the plurality of holders arranged in the second direction.

Optical connector, detaching jig, and cap

A measurement system is a measurement system inspecting an optical transmission line configured by connecting a plurality of optical cables, each of which includes a plurality of optical fibers, wherein the optical transmission line includes a plurality of optical fiber lines configured by connecting the plurality of optical fibers in the plurality of optical cables, the measurement system including: a first measurement device configured to be disposed at a first end of the optical transmission line; and a second measurement device configured to be disposed at a second end of the optical transmission line, wherein the first measurement device and the second measurement device perform a first measurement to inspect whether the optical cable is misconnected, and a second measurement to inspect the plurality of optical fiber lines in a case where it is determined that there is no misconnection in the first measurement.
