Abstract: In a box having an openable front face, plural fiber loop supports substantially flat and movable can be laid out parallel with the front face of the box. Connector bars are respectively attached to the supports and are used for two by two connecting the optical fibers. Slides on sliding rails attached in the box enable the supports to be translated together substantially perpendicular to the front face and completely outside the box. A support-bearing rod is rotatively mounted between the slides so as to turn the supports together outside the box and around an axis of rotation substantially parallel with the front face. The inside of the box is then accessible. Each of the supports can pivot around an axis perpendicular to the support so as to be cleared away from the other supports.

Abstract: A reserve device is provided for optical fibers, including a flat bottomed case with a core defining a recess having substantially the form of a closed loop omega, at the ends of which inlet and outlet channels are provided for the optical fibers, each fiber being protected by two tubular ducts leaving it bare, coiled about said core, said tubular ducts being immobilized in the inlet and outlet channels when the case is closed, said core including a central part integral with the case, surrounded by a removable ring intended to be removed after coiling of the optical fibers.

Abstract: Two optical fibers are connected by a device including a base member having a central groove for aligning and abutting the fiber ends. To connect the fibers quickly without having to dismantle any device members, the device comprises a one piece bent spring fastener having a U-shaped cross-section. Natural flexion of a flexible arm of the spring fastener presses the fiber ends into the groove in the immediate vicinity of a fiber endface connection plane. The other arm is anchored to the base member. To connect the fibers, a tool deflects the flexible arm away from the base member and the fiber ends are slide into the groove. The device is in a very slim-like housing and several can be stacked to create a multifiber connecting rack.
