Abstract: An optical fiber rack includes a rack part on which a termination unit is located, and an optical fiber housing part for housing an extra length wiring part in an optical fiber bundle, the optical fiber housing part being positioned in a first direction. The termination unit includes a plurality of first optical fibers, a ay provided on one end side of the termination unit in a second direction, the tray being slidable in the second direction, and a plurality of adapters which are arranged in a line on the tray. The tray has a first support part for supporting the optical fiber bundle, the optical fiber rack further includes a second support part arranged in the second direction with respect to the first support part, and the second support part stretchably supports the optical fiber bundle extending from the first support part to the optical fiber housing part.

Abstract: [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 closure 118 has a case 121, while a plurality of connecting modules 123 are arranged (stored) so as to be erected with respect to the bottom face of a closure main body 119 along the width direction in a module storing section 122 of the case 121. The connecting module 123 has a rectangular parallelepiped board-like module main body 127, while a plurality of MT connectors 128, 129 are attached in a vertical row to one end face of the module main body 127. In the module main body 127, an optical connecting section 130 for connecting the MT connectors 128, 129 to each other is arranged. The module storing section 122 can store a different kind of connecting module having a connecting configuration (function) different from that of the connecting module 123.
