Lucent Says New Fiber Will Improve Capacity By A Third - By Grant Buckler, Newsbytes Researchers at Lucent Technologies Inc. [NYSE:LU] said they have solved a problem that has been watering down the performance of optical fiber. The company said its new AllWave Fiber will offer about a third more capacity by making 50 percent more usable light wavelengths available for transmitting data. The secret to AllWave fiber, which Lucent is currently producing at a factory in Atlanta, is water molecules -- or rather the lack of them. A certain amount of water is always retained in optical fiber as it is manufactured. In most fiber, Lucent spokesman Roger Frizzell told Newsbytes, certain wavelengths cannot be used because they are too sensitive to the water molecules that are left in the fiber. Lucent has developed and patented an ultra-purifying process that gets almost all the water molecules out, meaning that wavelengths formerly made useless by the "water peak" can now be used. According to Lucent officials, all of this will mean more bandwidth for applications such as cable television and data on demand. AllWave fiber could make it possible for local telephone service providers to offer 10-gigabit-per-second (Gbps) data service over longer distances. The new fiber is also suitable for use with 1,400-nanometer lasers. Such lasers have not worked well with conventional fiber, again because of the water molecules present, but they will work with AllWave. Frizzell said the 1,400-nanometer lasers are ideal for metropolitan-area networks, allowing for fewer repeaters than the 1,500-to-1,600-nanometer lasers used today. Lucent is aiming AllWave particularly at metropolitan-area applications, he said. The new fiber can be used with existing lasers as well, and can be installed anywhere current fiber is used without changing other components of the network, Frizzell said. The increased bandwidth is also available without replacing other components. Article posted on 06/06/98
