An optical fiber distribution frame including a first cross-connection panel and a second cross-connection panel facing each other, and a first support in each panel for connection modules. Each module on the first panel is adapted to be connected to one end of an optical fiber of a first group, each module on the second panel is adapted to be connected to one end of an optical fiber of a second group, and an optical fiber of the first group is adapted to be connected to an optical fiber of the second group by a jumper fiber which has two ends respectively received in a port of one of the modules on the first panel and in a port of one of the modules on the second panel. The first and second panels each include a second connection module support, with said second supports cooperating with each other to form a storage area for jumper fibers that are not in use and awaiting connection. The jumper fibers are automatically connected or disconnected by a device.
