Abstract

An office panelling system is advantageously combined with fiber optic communication cable wherein the panels of the system are generally open in the center thereof and the vertical space of the panel is advantageously used for reducing the curvature of the cable between panels disposed at an angle. The panels have a metal framework onto the sides of which cover members are secured such that the interior of the framework is generally open. The framework includes a host of distributed passage ports therethrough for allowing communication cables and the like to pass through the framework where desired. The fiber optic communication cable is strung through the frameworks of the panels and rounds corners between panels disposed at an angle by using both the vertical and horizontal planes of the framework to provide a curvature in the cable rounding the corner between angled panels much greater than the angle of curvature of the cable if the cable was confined to a single horizontal plane for rounding the same corner. The rate of curvature of the cable is important, as in fiber optic cables light loss is encountered with any corner and the extent of the light loss increases as the radius of curvature becomes smaller. It is the general practice that the rate of curvature chould not be less than ten times the diameter of the cable.
