Crosswave uses synchronous optical network (sonet) and wavelength division multiplexing (dwdm) technologies, which enable it to transmit data at high speeds over long distances with a high degree of reliability.

FORBES: 20 FOR 2000

However there are lots of commercial issues with a UV optical disc besides creating inexpensive devices to generate this wavelength of light.

FORBES: What is the Future of Optical Disc Technology and who will Use It?

This is the wavelength of the infra-red light normally used in optical communications.

ECONOMIST: New-age crystals

Today, optical fibers can transport 10 billion bits of data per second on a single wavelength.

FORBES: Wired and restless

Optical lithography techniques become increasingly problematic as engineers build tinier devices--the wavelength of the light used to cast patterns onto silicon is already bigger than the width of the devices engineers want to create.
