A 100 Meter 12 GbsLane Copper Cable Link Based on Clock-Forwarding

Abstract

Active and passive copper cables for data rat es ex- ceeding 10 Gb/s are typically limited to less than 20 m. Optical fiber on the other hand offers superi or performance for run length greater than 100 m, but is costly. Although 100 m copper link is demonstrated for 10GBASE-T, i t utilizes complex symbols at a lower symbol rate across multiple signaling lanes and dissipates substantial power for DSP. In this paper, we propose a 12 Gbps/ lane active cable link that extends copper cables 100 meter
