What’s the Tsukuba WAN ?

Tsukuba WAN is the network for research collaboration and

cooperation among industry, university and government.

It links with many institutes in Tsukuba area by ultrahigh-

speed access ring network.

As a result, they are able to use almost recourse of research institutes in Tsukuba, such as supercomputer, large-scale database, and computer simulations software.

Construction of Network began in 2000, and operation started at May 2002. The Tsukuba WAN symposium was held at May 2, 2002 as Opening ceremony.

At the symposium, some program occurred such as the presentation on the results of research, which was using Tsukuba WAN, and discussion about the concept.

Tsukuba research organization in SuperComputer TOP500

TOP500 List for November 2002

http://www.top500.org/list/2002/11/

8 places and 11 systems of supercomputer in Tsukuba are rank in. TOP500 of the world.

If they connected each other by Tsukuba WAN, it would become global area of technology and an industrial simulation field.

The method of transmitting 1 55um signals on smf

The method of transmitting 1.55um signals on SMF

When 1.55um signals transmits on SMF (Single Mode Fiber, 1.3um zero-dispersion optical fiber), it is necessary to do dispersion compensation, because of chromatic dispersion degrades optical signals
