Why is fiber optic DSL the same speed as before?

Episode 1290 (47:17)

Steve from Los Angeles, CA

Steve isn't seeing much of an improvement after being upgraded to fiber optic DSL because he still has copper lines coming into his house. Leo says that Steve should ask for fiber optic directly to the house. Otherwise, it's essentially little difference. Could he upgrade it himself? That's a good question. But buying his own fiber optic switch isn't cheap.
