Clifton has one of the more varied broadband markets in northern New Jersey. Current FCC-derived market data identifies Optimum and Verizon as fiber providers, Optimum and Xfinity as cable providers, and T-Mobile, Verizon and AT&T as fixed-wireless alternatives. Optimum reports fiber service up to 8 Gbps, while Verizon's reported Clifton fiber maximum is about 2.3 Gbps. Xfinity is also present, but its reported Clifton coverage is substantially narrower than Optimum's cable footprint. A citywide provider list does not establish which network reaches a particular house, apartment or unit.
A ZIP code identifies the general Clifton market, but it does not establish which fiber, cable or fixed-wireless network reaches a particular property. Use the complete service address with the provider for the final availability check.
The ZIP-page redirect is a starting point. Provider websites remain the authoritative source for current address-level eligibility, plan pricing and installation terms.
Clifton's broadband market has two reported fiber networks, two cable networks and several fixed-wireless alternatives. The important comparison is not simply the number of providers. Technology, upload capacity, reported local coverage and the offer returned for the exact property can be materially different.
Current Clifton market data identifies Optimum and Verizon as fiber providers. Optimum reports symmetrical service up to 8 Gbps, while Verizon's reported fiber maximum is about 2.3 Gbps. The reported coverage figures are market-level estimates, not proof that both networks reach the same property.
Compare Clifton fiber providers →The city's planning material identifies areas including Lakeview, East Clifton, Botany, Clifton Center, Middle Village, Greglawn, Richfield, Dutch Hill, Athenia, Rosemawr, Delawanna and Allwood. These local boundaries help describe Clifton's geography, but they are not ISP service boundaries.
See Clifton availability notes →Clifton's reported fiber networks offer symmetrical upload and download capability. Xfinity's reported cable maximum is 2 Gbps down and 250 Mbps up, while Optimum cable is reported at up to 940 Mbps down and 35 Mbps up. That difference matters for large uploads, cloud backups and other upstream-heavy use.
Compare technologies →The current Clifton market dataset reports Xfinity cable coverage at about 21% of the city's reporting area, compared with 100% reported Optimum cable coverage in the same dataset. These are aggregated market figures and should not replace an address check.
See methodology →The comparison focuses on providers supported by current Clifton-specific market data or current provider information. Coverage figures describe the Clifton reporting area and should not be treated as address-level guarantees.

Market coverage and maximum speeds are based primarily on FCC Broadband Data Collection information represented in current Clifton market data, reflecting provider-reported availability as of December 2025 with FCC revisions through July 2026. Coverage figures are aggregated to the Clifton reporting boundary and are not guarantees for individual homes or apartment units. Provider pricing and plan information were reviewed September 24, 2026 and can change.
Clifton has two reported fiber networks and two reported cable networks, with fixed-wireless services providing another set of address-qualified choices. Optimum appears in both the fiber and cable categories, while Verizon separately operates Fios and 5G Home.
Verizon's Fios network is one of the two fiber networks reported in Clifton. Verizon currently publishes Fios tiers from 300 Mbps through 5 Gig where available. The Clifton market dataset reports Verizon fiber with a maximum advertised speed of about 2.3 Gbps. The exact tier returned by Verizon depends on the property.
Optimum maintains a Clifton-specific internet page and currently lists 1 Gig, 2 Gig and 8 Gig fiber plans. Current Clifton market data reports Optimum fiber across the city reporting boundary. Optimum also has a separate cable footprint, so the technology and plan available at an individual property should be confirmed before ordering.
Xfinity is present in Clifton, but its reported local footprint is much narrower than Optimum's. Current Clifton market data reports about 21% cable coverage, with maximum advertised speeds of 2 Gbps download and 250 Mbps upload. Xfinity also lists Clifton among its New Jersey service areas. The complete service address should be checked before treating Xfinity as an option.
Optimum appears in Clifton market data as both a fiber and cable provider. The cable portion is reported at up to 940 Mbps download and 35 Mbps upload, while the separate fiber network reaches much higher symmetrical speeds. The distinction matters when comparing an Optimum offer returned for a specific property.
Verizon 5G Home is separate from Fios and uses Verizon's cellular network. Current Clifton market data reports Verizon 5G Home across the reporting boundary with a listed maximum of 300 Mbps. Verizon determines actual eligibility and service options at the address, and wireless conditions can affect performance.
Current Clifton market data reports T-Mobile 5G Home throughout the reporting boundary, with a maximum of 498 Mbps download and 55 Mbps upload. T-Mobile's current base plan is $50 per month with AutoPay before applicable taxes and fees. The company describes its home internet service as unlimited and without an annual contract, while actual performance depends on the cellular network.
AT&T maintains a Clifton-specific Internet Air page and describes the service as wireless home internet powered by its 5G network. LTE may be used depending on signal availability. Current Clifton market data reports AT&T Internet Air across about 94% of the reporting boundary, but AT&T still requires an address qualification check.
Clifton households can encounter fiber, cable and fixed-wireless plans. The useful plan size depends on simultaneous users, applications, connected devices and the home's local network rather than on the city itself.
Suitable for ordinary browsing, HD streaming, video calls and routine connected-device use. A 300 Mbps plan provides additional capacity for several devices operating together.
Provides more capacity for simultaneous streaming, remote work, gaming and connected devices. Clifton's fiber, cable and fixed-wireless markets all include services in or above this range.
Useful for larger households, frequent large downloads, cloud backups, gaming and several simultaneous high-bandwidth activities. Both Clifton fiber networks and Optimum cable extend into this range.
Relevant when multiple users and wired devices can actually use additional bandwidth. Optimum, Verizon and Xfinity report service reaching at least 2 Gbps in parts of the Clifton market.
Relevant for demanding wired workloads, large transfers and networking equipment capable of handling multi-gig traffic. Verizon currently publishes Fios service through 5 Gig where available.
Optimum currently advertises an 8 Gig fiber tier in Clifton. Multi-gig service requires compatible routers, switches, Ethernet connections and client devices. Wi-Fi throughput can be substantially lower than a plan's wired maximum.
Connection technology matters because advertised download speed does not describe the entire service. Upload capacity, latency, network architecture and address-level availability can differ substantially between Clifton providers.
Current Clifton market data identifies Verizon and Optimum as fiber providers. Optimum reports symmetrical service up to 8 Gbps, while Verizon's Clifton market data reaches about 2.3 Gbps. Verizon's consumer lineup extends through 5 Gig where available. Fiber provides substantially more upload capacity than conventional cable.
Xfinity and Optimum appear in the Clifton cable market. Current market data reports Xfinity up to 2 Gbps down and 250 Mbps up, while Optimum cable reaches up to 940 Mbps down and 35 Mbps up. Xfinity has a much smaller reported Clifton footprint than Optimum, so an address check is particularly important.
Verizon, T-Mobile and AT&T offer wireless home-internet products that can serve qualifying Clifton addresses. These services use cellular networks rather than a wired connection to the home. Eligibility and performance depend on signal conditions, network capacity and the individual property.
Clifton's geography is divided into numerous locally recognized neighborhoods, and the city sits within a dense northern New Jersey suburban corridor. The city's 2025 draft Open Space and Recreation Plan identifies neighborhood areas including Lakeview, East Clifton, Botany, Clifton Center, Middle Village, Greglawn, Richfield, Dutch Hill, Athenia, Rosemawr, Delawanna and Allwood. Those boundaries are useful for describing where a property sits, but they do not establish ISP infrastructure.
Current Clifton market data identifies Optimum and Verizon as fiber providers. Optimum advertises service up to 8 Gig, while Verizon's current Fios lineup extends to 5 Gig where available. The networks are separate, so the presence of one fiber network does not prove that the other reaches the same building.
Xfinity is listed as a Clifton cable provider, but the current market dataset reports only about 21% cable coverage within the Clifton reporting boundary. Optimum cable is reported across the full boundary in the same dataset. This is a useful reason to avoid assuming that every major cable provider serves every Clifton street.
Clifton's neighborhoods include areas such as Botany, Lakeview, Allwood, Dutch Hill, Athenia, Rosemawr and Delawanna. ISP infrastructure can cross those neighborhood boundaries or stop at individual streets, buildings or units. The final comparison therefore has to be made at the service address.
Clifton's official planning material identifies a network of distinct neighborhoods throughout the city. These names help identify local geography, but they should not be treated as proof of provider availability.
The city includes northern, southern, eastern, western and central neighborhood areas, with the Garden State Parkway and major roads dividing portions of the community. The final provider check should always use the complete street address.
Verizon and Optimum are both reported as fiber providers in Clifton. Optimum and Xfinity are reported as cable providers, while Verizon, T-Mobile and AT&T provide separate fixed-wireless products.
For an individual house or apartment, start with the exact address, review the FCC National Broadband Map, then check Verizon, Optimum and Xfinity directly. Compare fixed-wireless options separately because cellular eligibility does not establish availability of a wired connection.
Clifton also has satellite alternatives. Current Clifton market data reports Starlink, HughesNet and Viasat in the broader market. These services can be relevant where wired or terrestrial fixed-wireless choices are unavailable, but they should be evaluated separately from Clifton's fiber and cable networks.
Provider lists explain the Clifton market, but they are not substitutes for an address-level availability check.
The FCC National Broadband Map allows consumers to search an individual location and review providers, technologies and reported speeds at that location. The underlying Broadband Data Collection program relies on provider-submitted availability data.
Enter the complete street address, including apartment or unit information where applicable. Verizon, Optimum, Xfinity, T-Mobile and AT&T can then determine which service and plans are currently eligible at the property.
Look beyond the headline monthly price. Check the regular rate, promotional period, equipment, installation, data policy, contract terms and upload speed before comparing plans.
Use the ZIP page as a starting point, then verify service directly with the provider.

This page was researched using current provider information, FCC Broadband Data Collection information represented in current Clifton market data, and City of Clifton planning material. Provider advertising is treated as a statement of what the company currently publishes, not as independent proof that every Clifton address can receive the service.
Provider pricing, plan names, availability and network capabilities can change. FCC broadband data is useful for comparing reported availability but does not independently guarantee that a provider will accept an order at a particular address. Provider websites remain the final source for current eligibility, pricing, installation requirements and plan terms.
