In data centers, enterprise networks, and even high-performance computing clusters, high-speed interconnect cables are indispensable "capillaries." In short-distance interconnect scenarios, a pair of cables, each with its unique advantages, almost dominates the connection from inside the server rack to adjacent racks—these are DAC (Direct Connector Copper Cable) and AOC (Active Optical Cable). Oft...
