Bell Labs Extends 3-Tb/s Transmission

Bell Labs in Murray Hill, N.J., has announced successful long-distance transmission at triple-terabit speeds. The researchers displayed transmission of 82 wavelengths at 40 Gb/s over three 100-km spans of parent Lucent Technologies Inc.'s TrueWave fiber.

The experiment employed 40 channels in the C-band and 42 in the L-band. Both dense wavelength division multiplexing and distributed Raman amplification techniques were used to produce 3.28-Tb/s transmission.
