Overview:

:. Information flows.

Worldwide broadband access. Convergence of data, video, and telephony services.

Electronic processing with optical communications

Availability of raw processing power and custom communication chip design allows routing protocols and other software functions to operate in hardware.

Lasers, optical components, materials and techniques are evolving that exploit quantum-mechanical behaviors to process information and transmit it securely over long distances at high bandwidth.

The optical network makes use of these technologies to provide reliable high bandwidth channels for global connectivity..

Will it be SONET?, ATM?, IP Packets on fiber?

What about Voice (IP Telephony), Video (HDTV, DTV, ...) integration, and the Quality of Service you need to do it?

WDM (Wavelength Division Multiplexing), DWDM (Dense WDM)? How many channels?

What next? Hybrid? or all-optical? WDM or TDM?

See FAQ section

Both technological and market forces are at work. The industries that participate in this redefinition of infrastructure are in telecommunications, data communications, finance, media, and essentially the entire information distribution chain. The demands for bandwidth, reliability, global reach, and low-latency switching will be enormous.

This site tries to act as a clearinghouse for links to interesting and relevant subject matter in the field of optical networks. The emphasis is on the evolving science and technology aspects of optical communications.
