Multi-gigabit communications present many challenges to cable manufacturers. How can bandwidths higher than 10Gbps required by new standards such as HDMI™ and DisplayPort be achieved over low cost cables? What are the core technical problems with achieving these high data rates and what technologies can be used to address them? How can manufacturers achieve solutions which are less dependent on copper pricing? How can reliability issues be resolved without the need to use thicker cables? Cable manufacturing techniques have evolved to try to meet the challenge, but semiconductor solutions are emerging as promising alternatives and can be expected to play a significant role in solving these issues.

This article explains the physical problems faced by cable manufacturers, in particular...
