Number 68 (Story #5), February 21, 1992 by Phillip F. Schewe and Ben Stein 10 GIGABITS OF DATA can now be transmitted, largely without errors, over distances of 11,000 km. Linn Mollenauer of AT&T Bell Labs encoded the data in the form of solitons, pulses that retain their shape, which traveled through special erbium-doped optical fibers. Mollenauer reported this new work at the Conference on Optical Fiber Communications last week in San Jose, CA.
