Frank - that is some great info! That sort of message raises the signal/noise ratio significantly :-) In my original reply, I wanted to emphasize the similarity between copper and glass - in both cases, the signal in fact propagates in a dielectric material, and not "in the wires" as is often thought. But your notes show just how subtle the issues are when one want's to have a more precise handle on what is happening. A propos my question on splicing, I honestly wondered what is done these days, as I had the impression one avoided splices like the plague. In my neighborhood, Cablevision is upgrading to HFC, and they "loop" the fiber up and back on the utility poles with these things that look like tennis rackets to widen the turn radius. When I asked, the installer explained that it was to provide slack in case a pole is struck down! Finally, I'd like to add to your links a pointer to the HP fiber optic training manual: semiconductor.agilent.com Just follow the links to "literature" -> "networking literature" -> "technical training and designers guide" to reach the document in PDF form. I don't know why they prevent one from just citing the link, but this document is well worth looking through!
