Abstract: A coupling structure couples an optical termination (T1/T5) of an optical fiber conductor (F1/F5) to an optical terminal (T1'/T5') of an optical device which can be another optical fiber conductor. The structure includes a carrier (S, P) wherein the optical fiber conductor is embedded therein to have at least one locally bent portion reaching an outer surface of the carrier and forming there the optical termination. The carrier includes a first positioning device (P) to correctly position the optical termination with respect to the carrier and a second positioning device (L1-L3) which cooperates with a third positioning device (s1, s2, s3) of an optical arrangement including the optical device to provide the coupling.

Abstract: An interconnection unit OB includes a flat member FM with connectors OC1, and flexible tongue-shaped elements T formed to be integral with the flat member FM. Conductors F each have a first end part fixed to one of the tongue-shaped elements T and a second end part fixed to the flat member. The tongue-shaped elements T and the flat member FM are formed of a layer of rigid material and each of the tongue-shaped elements T has a portion thereof that includes separated transverse strips S, which are kept together by the conductors F fixed to the tongue-shaped elements, thereby making the tongue-shape elements flexible. A stainless steel plate is fixed to the rigid layer. The interconnection unit is especially useful as an optical backpanel to interconnect optical connectors of printed boards mounted in a rack.
