Page "Moore's law" Paragraph 25

Network capacity.

According to Gerry / Gerald Butters, the former head of Lucent's Optical Networking Group at Bell Labs, there is another version, called Butter's Law of Photonics, a formulation which deliberately parallels Moore's law.

Butter's law says that the amount of data coming out of an optical fiber is doubling every nine months.

Thus, the cost of transmitting a bit over an optical network decreases by half every nine months.

The availability of wavelength-division multiplexing ( sometimes called " WDM ") increased the capacity that could be placed on a single fiber by as much as a factor of 100.

Optical networking and dense wavelength-division multiplexing ( DWDM ) is rapidly bringing down the cost of networking, and further progress seems assured.

As a result, the wholesale price of data traffic collapsed in the dot-com bubble.

Nielsen's Law says that the bandwidth available to users increases by 50 % annually.
