Bell Labs Achieves Transmission of a Terabit of Information

Scientists from Bell Laboratories in Murray Hill, N.J., the R&D arm of Lucent Technologies, have reported a long-distance transmission of a terabit of information. Using an experimental ultrawideband optical-fiber amplifier, the researchers transmitted signals at the rate of 10 Gb/s over each of 100 wavelengths for nearly 250 miles.
In the past two years, the reseachers have demonstrated terabit transmission over relatively short distances. The 250-mile transmission distance is the longest achieved so far.
