[ILUG] New technology/ maybe OT

[Jason Corcoran.]

The "comb" would have to have a thicker granulairty than that,
100 colours would have inter and intra modal dispersion and interferance 
effects on each other, in multi mode fiber. Also the German fiber network 
uses mono mode fiber which would mean that they would have to time splice the 
different components of the light as they have only one "channel" (mode) in 
the fiber to use.
