Abstract
Abstract A flat panel-shaped waveguide support assembly (1) possesses couplings (3), which are for coupling together incoming and outgoing light waveguides (4,5). Light waveguides (4) are divided into two partial bundles which are guided along opposite sides of the support assembly. From here they are semi-circularly led to an opposite semi-row of couplings (3) so that the two waveguide bundles cross over one another. Thus a relatively large bending radius of curvature is provided while still permitting compact dimensions for the support assembly (1).

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
173 words
A flat panel-shaped support assembly for couplings of light waveguides, into which assembly incoming and outgoing light waveguides are hung in loops and connected arranged in rows parallel to the plane of the support assembly, said incoming light waveguides are branched into two separate bundles which are separately guided on the support assembly such that one of said bundles is connected to a semi-row of couplings and the other of said bundles is connected to the other semi-row of couplings, whereby the light wavegides of the two bundles are guided to the couplings from different sides of the support assembly, and such that the two bundles are guided along opposite plate-like longitudinal sides of the support assembly and semi-circularly extend to a respectively opposite semi-row of couplings in a mirror-inverted fashion and cross one another, and further wherein the support assembly includes a large-area opening in the central region between the opposite sides through which opening the conductors of at least one of said bundles are led to a respective semi-row of couplings.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
41 words

Claim 4
Dependent Claim
22 words
A support assembly in accordance with claim 1, wherein the support assembly includes grooved channels wherein individual incoming light waveguides are guided.
