Abstract (en)

[origin: DE19751557A1] In prior art, optical power dividers (2) are used to channel information signals in modern communication systems by means of optic fibers (4) pertaining to a plurality of devices which are internal to said systems. These dividers are designed in such a way that an optic fibre (F1...Fn) which is brought to the input is sub-divided into a plurality of optical fibers. In order to create order in said plurality of optical fibers, the sub-divided fibers are assembled into groups (FB1...FBn) so that each group (FB1...FBn) has the same structure as the fibers (F1...Fn) arranged at the input.
