San Diego, CA—The prototype for the first chip developed by New Visual Corp. pushes the data rate over common twisted pair wires up to 90 Mbits/sec. The technology can provide high speeds at fairly long distances, running at 16 Mbits/sec for more than a mile.
The Embarq chip, aimed at the so-called last mile of telecommunications wiring, should help lower costs by letting phone companies provide high speed communications to the home using existing copper wiring, the startup company says. Now shipping in prototype quantities, the chip provides its best speeds in the asymmetric mode, sending more data downstream than upstream. It runs at 90 Mbits/sec for distances up to 1,500 ft. By comparison, even the best DSL products rarely achieve 6 Mbits/sec at distances less than 1,000 ft. Peak speeds for cable modems are typically around 10 Mbits/sec.
In the Embarq's symmetric mode, peak speeds are half the rates of the asymmetric mode, topping out at 45 Mbits/sec. Typically, phone companies offer business subscribers symmetrical data, while providing asymmetrical data to residential subscribers, according to a New Visual spokesman.
Currently, two potential customers are evaluating prototype boards, with initial results that mirror simulation performance levels, the company reports.
