PCT No. PCT/GB88/00712 Sec. 371 Date Apr. 25, 1989 Sec. 102(e) Date Apr. 25, 1989 PCT Filed Aug. 26, 1988 PCT Pub. No. WO89/02180 PCT Pub. Date Mar. 9, 1989.A corner guide comprises a pair of hinged panels (1, 2) with an embedded duct (6) through which an optical fibre (7) can be threaded. The corner guide, for guiding an optical fibre (7) or the like around a corner (9) whose radius of curvature is less than a permissible minimum radius of curvature Rp for the fibre (7), guides the fibers (7) by means of the duct (6) along a path which extends into three dimensions. At the corner at the hinge between the panels (1, 2), the duct (6) passes through an "x-y" plane containing the corner at an angle for instance of 70 DEG . This enables an arrangement wherein the projection of the duct (6) onto the "x-y" plane includes a bend whose radius of curvature is less than Rp although the path itself does not include such a bend. The invention finds particular application in optical fibre installations in homes or offices, wherever a fibre has to turn a corner, for instance at the corner of a room. Alternatively it finds application in equipment served by optical fibers which include for instance a hinged panel to which the fibers must extend. |
