>It sounds very confused, as though the writer imagines a single distribution fibre is split evenly every time it comes to a house, so the signal after 'n' houses is then (2^-n).  But even then, optical transmission is very efficient and transmission loss has nothing to do with the splitter.  Not that I'm any expert on this stuff... 

AFAIK, light doesn't 'degrade' because it's in the glass. It's pulses of light, not radio waves w/ frequencies.

This is a pretty good explanation: http://www.explainthatstuff.com/fiberoptics.html

The question I have is are they installing single-mode or multi-mode fibre?
