Abstract
A branching arrangement for communication transmission links having a branching zone between an incoming cladded optical glass fiber and a plurality of outgoing cladded optical glass fibers with each of the glass fibers having a core enclosed in a casing characterized by the glass fibers being free of the cladding in the area of the branching zone, the core of the incoming glass fiber being surrounded by the cores of the outgoing glass fibers with the axes of all of the cores being parallel and the cores of the outgoing glass fibers being separated from the core of the incoming glass fiber by an interposed intermediate material, and the cores of the incoming and outgoing glass fibers and the intermediate material being surrounded by a casing material which has an index of refraction lower than the index of refraction of the cores and the intermediate material having an index of refraction which is approximately equal to the index of refraction of the cores.
