Another deviation slightly off topic is the issue of bandwidth. It was recently a conclusion that the public networks would come to a halt as all this internet/data traffic usage way outpaced system capacity.

Well, we don't hear this too much anymore. Wonder why? DWDM.

"Dense wavelength division multiplexing (DWDM) arrived with a bang earlier this year with the announcement that Cable and Wireless had applied the new optical technology to its trans-Atlantic fiber trunks. Cable and Wireless did this by multiplying the number of infrared bands that the trunks can support. Many experts believe that DWDM is a major step toward a National Information Infrastructure (NII) that one day could accommodate a limitless amount of information.

In essence, DWDM increases dramatically the information handling ability of single-mode fiber. It weaves this magic by dividing the infrared light emitted by the laser into multiple wavelengths and by assigning an end-user payload to each wavelength. The long-term implications for both the public carriers and the customers they serve are both exciting and far reaching. "

So, why should we need those ever faster high end computers or larger disk drives for that matter? Some say bandnwidth obstacles have held back the killer apps that will unfold as our computers become more connected to the public network. If you agree, this article is a good one.
