Quick Verdict
Choose Optimum if: you’re in its 21-state footprint (strongest in NY/NJ/CT) and want a price lock (1 year, or up to 3 years with an add-on) or the cheapest streaming-first TV package.
Choose AT&T Fiber if: it reaches your address — AT&T Fiber is 100% fiber-optic everywhere it’s built, with symmetrical upload speeds and a broader multi-state footprint across the South, Midwest, and West.
Which one fits you?
Pick the closest match for a plain answer.
I’m in NY, NJ or CT
Optimum — tri-state fiber core
Optimum’s fiber is concentrated in the New York tri-state area, and its 8 Gig tier is available in select markets. If you are in the NY/NJ/CT fiber core or elsewhere in its 21-state footprint, Optimum is a strong fit.
I’m in Texas or the South
Check both — overlap states
The two footprints overlap in a handful of states (Texas, and parts of the South), but for most addresses only one of the two is actually buildable. Checking availability at your specific address matters more than comparing brand reputations.
Upload speed matters
AT&T Fiber — video calls, large uploads
AT&T Fiber is 100% fiber-optic on every plan it sells, so you get symmetrical upload speeds on every tier. Optimum’s cable (HFC) network caps upload speeds well below download. If AT&T Fiber reaches you, it is the more consistent choice.
I plan to stay put
Optimum — longest price protection
Optimum’s price-lock add-on (up to 3 years) gives it an edge for anyone planning to stay put. AT&T does not advertise a multi-year price lock on its Fiber plans page.
I want TV too
Optimum — streaming-first TV
Optimum offers streaming-first TV packages starting at $20/mo. AT&T no longer sells its own traditional TV service directly; DirecTV, AT&T’s former TV arm, is the closest equivalent.
I want a mobile bundle
Depends on your tier — flat credit vs tiered discount
Optimum gives a $20/mo credit toward internet with Unlimited Mobile, while AT&T takes $15 to $25 a month off its fiber prices with an eligible AT&T wireless plan. Which one saves more depends on your internet tier.
Check Which One Reaches Your Address
Optimum and AT&T Fiber serve mostly different parts of the country, so availability decides it before price does. Tell us your address and we will check both.

Fiber vs. Cable Is the Real Story
AT&T Fiber is 100% fiber-optic on every plan it sells — there’s no cable fallback tier, so if AT&T Fiber shows as available at your address, you’re getting symmetrical upload speeds no matter which tier you pick. Optimum’s fiber is concentrated in the New York tri-state area; everywhere else in its footprint, you’re most likely on Optimum’s cable (HFC) network, which caps upload speeds well below download. If symmetrical upload matters to you — video calls, large file uploads, content creation — and AT&T Fiber reaches you, it’s the more consistent choice.
Where Each Provider Actually Reaches
Optimum’s 21-state footprint is concentrated in the Northeast (NY, NJ, CT core) with lighter coverage across parts of the South and West. AT&T says its fiber service now extends to 32 states, with meaningful density in Texas, Georgia, Florida, North Carolina, Ohio, and the broader South and Midwest. The two footprints overlap in a handful of states (Texas, and parts of the South), but for most addresses, only one of the two is actually buildable — checking availability at your specific address matters more than comparing brand reputations. See our Optimum availability guide or call Telemedia Solutions to check both.
Mobile Bundle Comparison
Optimum Mobile runs on T-Mobile’s network, with Unlimited plans from $20/mo per line on 3+ lines and a $20/mo credit toward your internet bill. AT&T’s own wireless network backs its mobile plans, and bundling an eligible AT&T wireless plan with AT&T Fiber lowers your fiber price by $15 to $25 a month depending on tier, instead of a flat dollar credit — which one saves more depends on your internet tier (AT&T’s saving grows from $15 on 300 Mbps to $25 on 5 Gig). Neither requires a contract. For the full Optimum Mobile breakdown, see our Optimum Mobile Plans guide.
Which One Should You Choose?
Choose Optimum If…
You’re in the NY/NJ/CT fiber core or elsewhere in Optimum’s 21-state footprint, want the longest price-lock protection (1 year, or up to 3 years with an add-on, while AT&T does not advertise a multi-year lock), or want the cheapest entry-level streaming TV add-on.
Choose AT&T Fiber If…
It’s available at your address — true 100% fiber with symmetrical uploads on every tier is hard to beat technically, and AT&T’s footprint reaches many states Optimum doesn’t touch at all.

Frequently Asked Questions
Can I get both Optimum and AT&T Fiber at my address?
Rarely — the two footprints barely overlap. Most addresses will only have one of the two available, so checking availability directly is more useful than comparing the brands in the abstract.
How many states does each provider cover?
Optimum’s footprint spans 21 states, concentrated in the Northeast (NY, NJ and CT core) with lighter coverage across parts of the South and West. AT&T says its fiber service now extends to 32 states, with meaningful density in Texas, Georgia, Florida, North Carolina, Ohio, and the broader South and Midwest. The two footprints overlap in only a handful of states.
Is Optimum fiber or cable?
Both. Optimum’s fiber is concentrated in the New York tri-state area; everywhere else in its footprint, you are most likely on its cable (HFC) network, which caps upload speeds well below download. Upload speeds are symmetrical on Optimum fiber only.
Is AT&T Fiber really fiber on every plan?
Yes. AT&T Fiber is 100% fiber-optic on every plan it sells, with no cable fallback tier, so if it is available at your address you get symmetrical upload speeds no matter which tier you pick.
Which one is faster?
AT&T Fiber’s 5 Gig tier and Optimum’s 8 Gig tier (select markets) are both far beyond what most households need. For the typical 300 Mbps–1 Gig range most people actually buy, speeds are comparable and pricing is close.
What are the top speed tiers?
Optimum’s top tier is 8 Gig at roughly $90/mo in select markets. AT&T Fiber’s top tier is 5 Gig at $110/mo ($85 with an eligible wireless plan). Both are far beyond what most households need.
Which is cheaper at each tier?
At the entry tier, Optimum is $35/mo for 300 Mbps versus $50/mo ($35 with an eligible wireless plan) for AT&T Fiber. At the mid tier, it is $45/mo for 500 Mbps versus $60/mo ($45 with wireless). At the Gig tier, Optimum is $55/mo versus $70/mo ($50 with wireless). Optimum rates were verified on October 14, 2026 and AT&T’s advertised rates (with Auto Pay and paperless billing) on October 14, 2026; actual pricing varies by address.
Which one is cheaper long-term?
Optimum’s price-lock add-on (up to 3 years) gives it an edge for anyone planning to stay put — AT&T does not advertise a multi-year price lock on its Fiber plans page.
How long is Optimum’s price lock?
Optimum’s plan cards advertise a 1-year price lock, and a $10/mo add-on extends it to 3 years; after the lock, increases of up to $15/mo per year apply. AT&T Fiber does not advertise a multi-year price lock.
Does either provider have data caps or contracts?
No. Neither Optimum nor AT&T Fiber has data caps or contracts.
Which has the better wireless bundle discount?
It depends on your internet tier. Optimum takes $20/mo off your internet bill with Unlimited Mobile (its Optimum Complete discount), which runs on T-Mobile’s network, with 3+ lines from $20/mo each. AT&T takes $15 to $25 a month off its fiber prices with an eligible AT&T wireless plan, and that saving grows with the tier (from $15 on 300 Mbps to $25 on 5 Gig). Neither requires a contract.
Does either offer TV service?
Optimum does, with its own streaming-first TV packages starting at $20/mo. AT&T no longer sells its own traditional TV service directly — for AT&T-area households wanting live TV, DirecTV (AT&T’s former TV arm) is the closest equivalent.
The Bottom Line
This isn’t really an either-or decision for most people — Optimum and AT&T Fiber serve mostly different parts of the country, so availability decides it before price does. Where they do compete, AT&T’s all-fiber network with symmetrical uploads is the stronger technical option, while Optimum counters with lower entry prices, optional longer price locks and cheaper entry-level TV.
