Their prototypes could boost the number of channels a single fiber can carry from 160 to up to 1, 000.
Thanks to an engineer's trick called "wave division multiplexing, " a single fiber-optic thread can carry upwards of 10 trillion bits per second.
In effect, Skype has created a worldwide voice network, capable of reaching as many consumers as the biggest phone companies, but it has done it without laying down a single fiber-optic wire.
Current "muxes" typically can push up to 100 light waves down a single fiber, but by year-end Nortel will begin shipping test gear that pushes 160 lightwaves, each carrying 10 billion bits of data per second.

The new single-laser fiber-optic speed record was set using a technique called fast Fourier transform that pulses light at an incredibly high rate with data encoded in 325 distinct colors across the spectrum.
Of the two labs, Fujitsu achieved the fastest transmission rate of 1.1 terabits per second, which were sent 150 kilometers over a single strand of optical fiber.
It is also a force in digital loop carriers, which convert multiple voice calls into a single digital signal and can use either copper or fiber-optic cables.
Beneath its carbon fiber skin the 6.5-litre V12 engine and seven-speed single-clutch gearbox get the car to 60 miles per hour in a flat three seconds.
And understand that even a single wearing (or probably a lot of try-ons with your new sweater) means your natural-fiber clothes (wool, silk, cotton, cashmere, fur including blends) are no longer sterile when it comes to insects.
