[Lucent Touts Milestone In Boosting Fiber's Transmission Capacity] NEW YORK -(Dow Jones)- Scientists at Lucent Technologies Inc.'s famed Bell Laboratories unit demonstrated a long-distance transmission of one trillion bits, or one terabit, of data over a single fiber-optic strand, Lucent said Monday. Murray Hill, N.J.-based Lucent (LU), which was spun off from AT&T Corp. in 1996, said the signals were transmitted using a new type of amplifier at a rate of 10 gigabits per second over each of 100 wavelengths, or colors, of light for a distance of nearly 250 miles. That would be more than twice the capacity of previous experiments, Lucent said. Lucent also reported a 1.2-terabit transmission with 40 gigabits of data per second carried over each of 30 wavelengths. Both transmissions used Lucent's TrueWave fiber for multi-wavelength transmission. Fiber-optic systems break data into quick bursts of light representing the zeros and ones of computer language - when the light is off, it represents a zero and when on, represents a one. Lucent has been touting technology that places a prism of sorts in front of the light to boost the number of signals that can travel down one line. Exploding Internet usage is driving the demand for increased line capacity. Building new "trunk" lines is expensive and major carriers prefer to increase the capacity of existing systems. Lucent has said it has developed a so-called dense wavelength division multiplexing system that can split certain fibers into as many as 80 virtual fibers that can travel down one line, or five times the bandwidth of current systems. AT&T has said it plans to deploy Lucent's system to double the capacity of its 40,000-mile fiber-optic network by year end. But some analysts say the fiber infrastructure to support such souped-up systems isn't yet in place and that the high price and limited volume availability will discourage widespread deployment until next year.
