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

[Problem] To provide an optical cable connecting closure and optical interconnection system which can easily respond to changes in required connection functions if any. [Solving Means] An optical cable connecting closurehas a case, while a plurality of connecting modulesare arranged (stored) so as to be erected with respect to the bottom face of a closure main bodyalong the width direction in a module storing sectionof the case. The connecting modulehas a rectangular parallelepiped board-like module main body, while a plurality of MT connectorsare attached in a vertical row to one end face of the module main body. In the module main body, an optical connecting sectionfor connecting the MT connectorsto each other is arranged. The module storing sectioncan store a different kind of connecting module having a connecting configuration (function) different from that of the connecting module
