Common questions about Optimum Fiber

How do I check if Optimum Fiber is available at my address?

Optimum Fiber is built out address by address, so a coverage map will not answer the question for a specific home — two houses on the same street can get different answers. Enter your street address in the checker on this page and FiberNear will confirm whether Optimum Fiber, or another fiber provider, can actually serve your location. It is free and there is no obligation.

Is Optimum Fiber fiber or cable?

Optimum Fiber is fiber. The connection runs on optical fiber all the way to the property rather than coaxial cable or a copper phone line, which is why fiber plans typically offer matching upload and download speeds where cable does not.

What speeds does Optimum Fiber offer?

Optimum Fiber plans commonly range from 300 Mbps up to 8 Gbps where the fiber build has reached the address. Tiers, pricing and promotional terms are set by Altice USA, Inc. and vary by address — confirm them with the provider before you order.
