Claim:
1. An optical interconnection assembly for the mutual connection of a plurality of signal switching circuit boards that are coupled to a common planar support, backplane, comprising: a planar support frame configured to receive an ordered arrangement of connectors, which includes a series of first connectors arranged to face corresponding signal transmission ports of said boards, and a series of second connectors arranged to face corresponding signal reception ports of said boards, an interconnection circuit housed by the support frame and disposed between corresponding pairs of first and second connectors according to a preset interconnection scheme, wherein said interconnection circuit comprises a plurality of arrangements of aggregated interconnection optical fibers extending along a longitudinal axis of the arrangement; and a controlled deformation guide means of said plurality of optical fiber arrangements configured to establish a corresponding plurality of non-intersecting coplanar paths of said optical fiber arrangements between corresponding pairs of first and second connectors, wherein each optical fiber arrangement of the interconnection circuit extends, in the path between the corresponding first and second connectors, with the longitudinal axis parallel to the plane of the frame, according to a trajectory that has curvatures around folding axes of the arrangement perpendicular to the plane of the frame, having curvature radius higher than a preset threshold value.
