Optimum's locations directory includes New Jersey, and the New Jersey page is the brand's state storefront for internet, TV and mobile. The fiber disclaimer is the sentence that keeps fiber and cable from being blended.

New Jersey is a published Optimum state

Optimum's locations index lists New Jersey among the states where it tells you to check availability. The New Jersey page itself is titled as Optimum in New Jersey and markets Optimum internet there. Altice is the parent named on Optimum's site. None of that is a line item for a specific apartment.

The about page's 21-state customer figure includes New Jersey customers among other states. It is not a New Jersey passings count you can turn into a coverage percentage.

Fiber portions and cable addresses can share the state

The fiber page says 8 Gig fiber is currently available in portions of New York, New Jersey and Connecticut, that fiber is not available in all areas, and that some areas get internet over a cable network with different speeds. A New Jersey address can fall in any of those buckets, or in none of them.

When you compare offers, keep the New Jersey fiber label and a New Jersey cable label in separate columns. Do not average their speeds.

Start from the New Jersey Optimum page only as a state confirmation.
Enter the full address and unit.
Record fiber or cable before you look at tier names.
If the result is cable, do not shop it as 8 Gig fiber.

New Jersey also has other home-internet brands

Verizon's Fios availability list includes New Jersey, and its 5G Home list does too. Those are Verizon products, not Optimum. Kinetic's 18-state fiber directory does not include New Jersey. Do not import a Kinetic fiber article into a New Jersey Optimum decision.

Check each brand that might build or serve the building. A dense New Jersey ZIP can still have one provider in the utility room and another that cannot enter.

What the state page is for

Use it to confirm you are in a state Optimum claims, then leave it for the address tool. Store locators and promotional banners on the state page are marketing. The order summary is the offer.

Illustration only: two units on the same New Jersey street return fiber and cable. Both can be consistent with Optimum's footnote. Neither result applies to the other unit.
