Abstract

High speed processing is reaching physical electrical limits. This structure is to address a high speed matrix connector of Opticube components from a circuit board to an optical backplane.

Optical Backplane for Matrix Connections

Figure 1 shows a side view of a circuit board (1) that has an Opticube assembly (2) attached to it. Since an matrix optical connection is needed to connect board to board, a fiber matrix connector assembly (3) is shown. The fibers are attached to the end of the Opticube (4) and are attached at the other end on a plate (5). When the card is pushed into the backplane it is roughly aligned in X and Y by an electrical edge connector (6) and the tab in it (7). The secondary and final precision is created by the chamfered hole and pin (7). The plate (5) slides into the located position with the final motion of the card. The spring force in the buckled (8) inline fibers (preferred) or an offset external spring (9) provides pin and hole misalignment and insertion force.
