Where does Optimum offer home internet?
Optimum's locations directory lists 959 communities in 21 states (checked Oct 27, 2026). In FCC data as of Dec 31, 2025, Optimum reports fiber at 2,276,354 locations and cable at 5,160,863 across the 16 of the 21 states covered here.
The fiber sits mostly in New York, New Jersey and Connecticut. In most of the rest, Optimum is a cable network. So the first thing to learn at a new address is which of the two you would get.
The longest lists are Optimum in New York, Optimum in New Jersey and Optimum in Texas. If your result shows fiber, pick an Optimum fiber tier. For what the technology changes at home, read fiber, cable and 5G: practical differences.

How to read a Optimum address result
- Enter your street address with the unit number, since one Optimum location can be a whole apartment building.
- Read the plan names: Optimum's fiber tiers carry the word Fiber. If a plan lacks it, ask whether the line is cable.
- If the result is cable, put its upload speed next to any fiber plan from another company at the same address.
How sure is each claim on this page?

- L2: FCC-reported (used on this page). Providers report the technology at each location to the FCC National Broadband Map.
- L3: Provider-coverage (used on this page). Optimum names the place on its own locations page (shown as "Listed by Optimum").
- L4: Provider-confirmed address. Only the address check reaches this level. It returns the offer for your street address and unit.
- L5: User-confirmed orderable. We never claim this level. You confirm it when you place the order.
