Telcos close to TV nirvana.

The age of interactive television and of the tripling of current available cable channels came a step closer when ATT's Bell Laboratories demonstrated a fiber-optic cable capable of carrying 6.8 billion bits of information simultaneously. The ordinary telephone wire can carry 64,000 bits. The thin strand of fiber-optic wire has the capability of carrying some 100,000 phone conversations simultaneously. The ATT experiment involved sending laser configurations over 520 miles of land lines. ATT said the fiber-optic wire could carry the telephone traffic for a small city. In fiber optics, computers fire lasers, which turn off and on in digital code. Optical detectors are then used to interpret the information. The ATT experiment used four lasers, firing in four "colors" or wavelengths.
