I happen to have on my desk right now a Verizon FiOS wiring plan for a 300-unit multiple dwelling in New York City. It has a separate fiber drop to every apartment and an ONT in each apartment that is subscribed to Verizon service. It has two layers of passive optical hubs and no powered components -- or, at least, no components that require building power. Whether any of the optical components are actually powered to allow remote testing, etc. I do not know but would tend to speculate likely not. I believe there is really, truly, a 300 fiber bundle running in from the street and that it's not actively multiplexed until that location. Maybe there are totally passive ways to do DWDM now so the passive "hubs" in the building actually have unpowered frequency multipliers/dividers in them -- I do not know. But it is unquestionably the case that even in multiple dwellings (and in this case we are talking about 15 separate buildings served by a single Verizon cable entrance!) VZ does bring the fiber all the way to the ONT in the customer's home. -- Thor Lancelot Simon tls@panix.com And now he couldn't remember when this passion had flown, leaving him so foolish and bewildered and astray: can any man?
