A research study made at Penn State University in Pittsburgh, revealed the possibility of transmitting extremely high speed data over copper. The theory sustains the real possibility of reaching 100 Gbps using the Category-7 wire at distances in excess of 100 meters. Currently, the technology permits high speed transfers only in a 70 meters range. The limitations come from the 65nm process technology, which cannot pass beyond 70 meters. Degradation, noise, data races per bit line, bounce, cross-over, and other factors are against today's technology.
However, the research team claims that new modems will be required to reach high speeds. Currently they are looking to evaluate the needs for such modems. Probably when the 32nm or 22nm chips will be ready, then the modems will be able to handle the signal switching with less bounce, less noise and ultimately without data loss. The technology is foreseen for 2013.
