[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

A container box for use in a communication apparatus. The container box has a container case defining an internal space; partitions connected to the container case for partitioning the internal space to have at least two accommodating chambers; and a container cover corresponding to each of the at least two accommodating chambers. Each cover is connected to the container case for independently closing and opening the at least two accommodating chambers. Wherein the at least two accommodating chambers each have differing degrees of waterproof level.

Container for use in a communication apparatus having a plurality from one another in waterproof level of independent chambers which are different

An attaching arrangement for attaching, to a communications apparatus container box, an optical cable case which includes a case body for accommodating an optical cable and a case end portion attached to the case body. The attaching arrangement includes: a first rotary hinge having a first rotary hinge axis for rotatably attaching the case end portion to the container box around the first rotary hinge axis; and a second rotary hinge having a second rotary hinge axis perpendicular to the first rotary hinge axis for rotatably attaching the case end portion to the container box around the second rotary hinge axis. In a preferred implementation, the attaching arrangement further includes: a slide rail slidably attached to an inner surface of the container box along a direction parallel to the second rotary hinge axis so that the slide rail is slidable from an inside of the container box to an outside of the container box and from the outside of the container box to the inside of the container box. The first and second rotary hinges rotatably attach the case end portion to a forward end of the slide rail in an advancing direction in which the slide rail moves from the inside of the container box to the outside of the container box.
