Being an Fiber Optics Communications veteran, I am watching the actual FTTH networks' s rollout with the highest interest.
Among other things, there is one topic which is of concern to me : Testing. I am pretty convinced that the 20-yrs old technics used for acceptance testing of optical links are totally out of sight in the case of FTTH : doing OTDR measurements from the subscriber's house is definitely not the most cost-effective method for budget-pressured telcos ;-)
Hence the idea of mixing physical layer (read : fiber), protocol layer (read : IP), and applications layer (read : TriplePlay Services - telephone, internet, television) in one single test. In short : allow the technician who does the cabling to verify the ability of the link to carry the whole pack of the TriplePlay services.
