An optical coupling assembly contains two or more individual, isolated, fused fiber couplers of type 1x2 or 2x2. The couplers are made from juxtaposed segments (15r, 15'r; 15b, 15'b) of individual fibers in two pieces of two-fiber ribbons (1, 1'). The juxtaposed segments have been fused to each other and simultaneously drawn in the conventional way. The coupling segments are placed inside an elongated protection element (21) having a groove or channel (19). The segments are secured in to the groove or channel and can be separated from each other either by being located at some distance of each other in the fiber longitudinal direction and by some suitable isolating material (23). Such a coupling element is particularly suited for building networks in which two-fiber ribbons are used, such as branched passive optical networks, in private homes, for duplex or bidirectional communication, but can also be used in any kind of coupler application instead of two or more separate couplers. |
