    摘要: Optical 1.times.N and N.times.N switching matrix has a tree structure. In the case of 1.times.N switching matrices having a tree structure, in which an optical input (1.sub.0) is connected to N outputs (1.sub.1) by means of an optical waveguide structure (1) which branches like a tree, and in which an optical changeover switch (4) is arranged in each junction point (3) of the waveguide structure, it is intended to improve the crosstalk suppression. To this end, in each case one gate switch (5) is assigned to each output (1.sub.1) for optional release and blocking of this output (1.sub.1) as a function of a switching state of the changeover switch (4) of a junction point (3) from which a branching waveguide (11) is connected to this output (1.sub.1). An N.times.N switching matrix, which is also described, having greatly improved crosstalk suppression can be obtained with such 1.times.N switching matrices. The switching matrix is used in optical communications networks, for example telecommunications networks.

    摘要: A coupling arrangement for optically coupling together, in a self-aligning fashion, inputs and outputs of an optoelectronic integrated circuit module and end faces of optical fibers with the module being arranged with a plane support surface flat on a plane bearing surface of a holder for holding fibers and a stopping device is provided for limiting a relative displacement between the module and the holder at a point at which the mutually-assigned end faces and inputs and outputs of the module are situated opposite one another. The electrical contacting of the module is performed by a continuous opening in the holder so that contacts extend through the opening to engage a surface of the module.
