Interesting comments on the comparison between using a single bidirectional fiber vs using two. For sure, distance will play into this, too, where route amplification and regeneration come into play.

There's a practical issue to consider also. Remember that with copper, they run several twisted pairs into the home when they originally wire you. That's just in case one line breaks (so they don't have to string a line again), and to allow an easier future upgrade. Don't the same considerations exist for fiber? If they're going to run a fiber line into a home shouldn't it almost certainly be a bundle? And, since you have a bundle coming into the house already, you/the telco can choose to use one or two of the fibers based on what's convenient or what you want to install in the CO. Also, re lasers: Wasn't it on the LM thread maybe a month ago that there was some discussion of high-powered pump lasers? . . . Maybe not, but here, fromn the Gorilla and Kings thread, concerning JDSU, etc.: Message 13062623 JDSU product announcements: "JDS Uniphase Extends Amplification Product Line to Meet the Need for Higher Functionality and Increased Power BALTIMORE--(BUSINESS WIRE)--March 6, 2000--JDS Uniphase Corporation (Nasdaq: JDSU and TSE: JDU) today announced a significant expansion to its line of amplification products for telecommunications and CATV applications. These new products include diode pump lasers and Raman pumps, as well as new amplifier modules for metro and long-haul amplification. Not exactly what I was thinking of, but . . . I know (think?) I'm talking apples and oranges here, but a laser is a laser. Once they have the ability in one application area, doesn't that give the bridge to another area?
