Bi-Directional Optical Backplane Bus with Multiple Bus Lines for High Performance Bus Systems

Over the past decade, the demand for more computing power has increased to such an extent that no single processor can provide the solutions in many applications. As a result, various efforts were made to build multiprocessor systems. Among those, systems based on electrical backplane buses, as shown in Fig. 1, have been prevailing in the commercial market mainly due to the ease of design and low cost. However, as the signal speed increases along the backplane, the transmission line effects become dominant, and the bus performance becomes limited by backplane physics1,2. Although advanced buses like Futurebus+3 guarantee an incident wave switching, other inherent problems degrade the performance significantly4. As new faster processors arise, the electrical backplane buses can no longer supply the bandwidth required for high performance multiprocessor systems.
