Optics have already found their way inside the data center (DC) by replacing electrical links for rack-to-rack interconnections. To cope with both the energy and bandwidth requirements, and to overcome the limitations of the electrical interconnects, DCs will have to deploy optical technologies not only in rack-to-rack but also in smaller packaging modules and lower levels of their architectures, namely board-to-board, on-board, and even on-chip. In this chapter the architectures proposed for these packaging levels are briefly surveyed. Implementing and laying out complex topologies via optical waveguides on the on-board (Optical Printed Circuit Boards) level presents a number of issues that have to be considered when designing architectures for DCs. To address these issues, we outline appropriate and general lay-out strategies for both point-to-point and multi-point topologies for OPCBs.
