• CATV feeds

    From Don Y@21:1/5 to All on Tue Nov 5 16:38:49 2024
    They're replacing the roads in our neighborhood. That
    means lots of excavation.

    CATV and phone are notorious for burying their lines
    REALLY shallow (*inches* as we have no frost heave to
    worry about).

    So, the CATV feeds have been dug-up in many cases.

    Is the signal that passes through these the same
    signal that is delivered to subscribers (i.e., just
    "split" off, no down conversion?)?

    What sort of power levels would be encountered?
    I assume there are multiple "feeds" to the neighborhood
    (a few hundred subscribers) so some sort of "head amp"
    upstream?

    Cornered a cable guy, yesterday. I was surprised that
    many of the "boxes" that I thought were TelCo are
    actually CATV kit.

    [Also, discovered some of these nondescript boxes have
    mains distribution cables (secondary). I will now "think
    twice" before standing on them to get a peek over the wall!]

    Yes, the signal on the cable is the same as what comes
    to your settop.

    He had no answer, there.

    Apparently, fibre is being used to get to many "areas"
    and "line extenders" are used to drive long lengths
    of cable.
