Optical interconnection unit for interconnecting optical

An optical interconnection unit, comprising:

• a flexible one piece flat member (FM), said one piece flat member including:
• a plurality of tongue-shaped elements (T) formed to be integral with the flat member;
• and
• a optical plurality of connectors (OC1);
• each of said plurality of tongue-shaped elements comprises a portion having a plurality of separated strips (S) which are positioned to be in a direction transverse to a plane in which said flat member (FM) is positioned;
• a plurality of optical conductors (F) fixed to said flat member,
• each of said plurality of optical conductors (F) having a first end portion thereof fixed to respective different ones of said plurality of tongue-shaped elements and having a second end portion thereof fixed to said flat member (FM);
• wherein:
• said plurality of tongue-shaped elements (T) and said flat member (FM) each comprise a layer of rigid material;
• and
• said plurality of separated strips (S) being kept together by the optical conductors fixed to the respective different ones of the plurality of tongue-shaped elements to thereby provide flexibility to the tongue-shaped elements.
