[RFI] VDSL (very-high-bit-rate digital subscriber line)

[qrv at kd4e.com]

Is it that they use a better fiber-to-copper converter at the street,
then split the lines to the homes, rather than running fiber to each
house & using a poorer quality converter?

I'm trying to understand the reason for interrupting the fiber prior
to the run from the street to each house.
