Cut a grove in the asphalt, lay in the fiber, re-fill the asphalt. But I've never seen it, or looked it up, so you're on your own there. JT | ||||||||||||||||||||||||||||||||||||||||

Given some of the roads around here, I'd be worried about fibre breaks. Incidentally, a company I used to work for, ran fibre along side railroad tracks. It worked fine, except for one day, when a large sink hole appeared under one side of the track, and took out the fibre. Then there's always "backhoe fade". ;-) | ||||||||||||||||||||||||||||||||||||||||

Yeah, I'd have issues with the road conditions as well. I would think it would have to be in highly urban areas as those roads seem to get the most attention. | ||||||||||||||||||||||||||||||||||||||||

Hi alodoiska, here in Fiji Islands, we have 2 companys [i.e Telecom] which both uses fiber optic. one has an advantage, they have underground pipes telecom chambers and all but the other dont but they have electrical post. so what the latter company did is that they run their cables from electrical post to post and they have now more advantage than the former compnay [underground]. this is only a suggestion. thank you ------------------------------------- alodoiska wrote: > Hello everybody,
