The rapid development of multimedia communications creates a need for ever-increasing data throughput. As data rate and port densities continue to increase, system designers must choose between two extremes to meet their connectivity requirements. Fiber optical interconnects allow extended reaches, but the system solutions are very expensive and power–hungry. Copper cables offer a low-power solution, but the thickness, weight and attenuation limit port counts.
As line rates over 10 Giga-bit-per-second, passive copper cabling will not support links over more a few meters; Intersil’s signal integrity product with Q-Active technology provides a 300% reach extension over passive copper solutions at the same time consuming 80% less power than competing optical solutions.
