Photons propagate at 0.65c in fibre - the exact speed does vary depending on whether its single or multimode fibre.
Hi Geoff - not to reveal my ignorance or anything, but ... is that 65 degrees celcius?
65% the speed of light in a vacuum ?
The equivalent EMR propagation speed in coppr is 0.75c
What is EMR?
Electo-Magnetic Radiation. Electrons don't count as EMR do they though, (hell they have a mass!) so data in the form we transmit it down copper won't move at this speed will it? aid -- Adrian J Bool | mailto:aid@u-net.net Network Operations | http://www.u-net.net/ U-NET Ltd | tel://+44.1925.484461/
