Interesting - too bad the US dropped the ball after the Gigabit Testbeds - http://www.cnri.reston.va.us/gigafr/ - 
started in the late 19-EIGHTIES!!!!!

A.  Giga House Town Project - Exhibition
This is a new project co-ordinated by Keio Engineering Foundation and financed by Industry and Government to 
demonstrate that graded index plastic optical fibre GI–POF, such as the Asahi Glass  ‘Lucina’ fibre (with attenuation 
less than 20dB/km with transmission extending from the visible to 1.3mm), can be used successfully in the ‘last mile’ 
LAN applications.  Such a network using GI-POF already exists (since 2-3 years ago) at Keio University operating at 1 
Gbps and connecting four building of the campus.  This network during the demonstration at the conference was 
referred to as the ‘Giga Island’ network. For this event, this giga island was connected through glass fibre (part of 
the Tokyo network) to the exhibition hall of the Hotel, where there was the ‘Giga House Town Project Exhibition’ and 
a ‘Telemedicine’ set up both of which were  using GI-POF (1 Gbps). Following the interconnection between glass and 
POF was the ‘Giga-Tree’ from which many POF connections were derived serving the giga-house and the telemedicine 
room. The giga-house can, in ‘principle’, have Gbps services and currently some 80 houses in a new condominium in 
Tokyo are fully equipped with experimental POF networks enjoying very fast (10-50 Mbps most likely) connections to 
the rest of the world.  Understandably, a very significant (perhaps the most significant) part of the giga-town 
project is ‘what type of services’ would one like to enjoy at home.  The need for older people to have access to 
telemedicine was quoted as an example, while a telesurgery example had been demonstrated during the teleconferencing 
session that was held during the first session of the conference and that was attended by almost 1000 invited 
representatives from industry.  The most important challenge of this ‘Giga House Town Project’ was consindered not to 
be the ‘hardware’ which after all had just been demonstrated, but the ‘content of the service’ for this highly 
computerised house environment that has been shown to be possible using GI-POF.
