Abstract: The cassette is mounted horizontally or vertically on a support rail and defines a front action face. One of its compartments is used for storing an excess length of optical cable while its other compartment is used for storing an excess length of optical jumper. The cassette includes a fixed first connection for the cable conductor and a removable cross-connection second connection for the jumper, said connections being mounted separately, substantially on the front action face, and being interconnected by an optical lead which is wound down together with the cable conductor and in the same compartment. The cassette is applicable to a distribution frame for telephones or computers.

Abstract: The invention relates to a universal assembly for connecting a processing terminal to a data transmission network. This assembly is constituted by a female connector (15) and a male connector (18). The female connector has two groups of connection terminals (28, 29) connected to ends of lines of network cable sections (7, 8). The male connector (18) is connected to a connection cable (5) of the terminal and has connection terminals (21) respectively entering into contact with a group of terminals (28, 29) of the female connector. This assembly also has, in the female connector, electrical, mobile linking means (35) retractable on inserting the male connector (18) in order to ensure the continuity of the communications on the network, prior to insertion and for ensuring the connection of the terminal to the network after insertion. Means are provided for ensuring the continuity of the earth or ground shields of the terminals of the male and female connectors and the shields of the cables.
