The maximum bandwidth you have access to is limited by the slowest
modem of the two (the one connected to your desktop, and the one in
your ISP's modem pool that you dial in to)

Not that you will notice on an 128K connection, and there are other
issues such as dns latency, rtt (round trip time) of packets depending
on what sort of routing your ISP has set up, does he peer locally with
other providers, have multiple redundant links using bgp instead of
static routes etc.
Last mile connectivity wise, fiber is a good bit faster than standard
copper (eithernet, POTS / plain old telephone system) etc as data loss
is far less, for starters.
However there are lots of other factors involved that you may not
notice a significant difference by the mere fact that the guy has
deployed fiber instead of copper for the last mile.
