Which country has a 10G network in the world?

Discover which countries and companies already offer 10G (10 gigabit) home or commercial networks in 2025, how 10G is delivered (fiber, PON, DOCSIS), who the main vendors are, and what this means for businesses and consumers.

Answer 

As of 2025, several countries already offer commercial or widely available 10 Gbps broadband services (often called “10G”): Singapore, South Korea, Japan and parts of China provide 10 Gbps home or enterprise services through fiber deployments, while the United States has major cable operators and industry groups (CableLabs, Comcast, Charter) actively preparing DOCSIS 4.0 / 10G cable upgrades and limited multi-gig product rollouts. Specific companies include Singtel, StarHub, M1, ViewQwest (Singapore); KT, LG U+, SK Broadband (South Korea); NTT and other Japanese ISPs; and leading Chinese carriers and vendors during 2024–2025 rollouts.

What “10G” really means

“10G” as a marketing and engineering term can mean slightly different things depending on context:

• 10 Gbps broadband to the home — a service that offers up to (or guaranteed) 10 gigabits per second downstream and often symmetrical or high upstream speeds. Usually delivered over fiber (XGS-PON, 10G-EPON, 50G-PON aggregated) or through high-end fiber Ethernet.

• Cable industry “10G” platform — an industry goal led by CableLabs and U.S. cable operators that targets a combination of 10× speed, lower latency, reliability and security on hybrid-fibre coax (HFC) networks by using DOCSIS 4.0 and other technologies; this is as much a roadmap as a single product.

Because of that variance, when we say a country “has 10G,” we mean there are commercially available (or widely marketed) 10 Gbps plans or active, large-scale deployments rather than purely lab trials.

Countries and companies that already offer 10G (examples and evidence)

1. Singapore — multiple ISPs offering consumer 10 Gbps

Singapore has been actively preparing for and commercializing 10 Gbps home broadband. The regulator (IMDA) introduced grants to support a national 10G next-generation broadband network and ISPs such as Singtel, StarHub, M1 and challengers like ViewQwest have introduced 10 Gbps retail plans or trials, with competitive pricing appearing in 2024–2025. Singapore’s small geography and dense fiber footprint make nationwide—or near-nationwide—10G rollouts commercially feasible.

What this means for users: Consumers in many urban areas can already buy 10 Gbps home plans (often with promotional pricing) or can be on a short waitlist as ISPs activate fiber ports.

2. South Korea — major carriers selling 10 Gbps services

South Korea, a longtime front-runner in broadband speed, has moved from gigabit offerings to 10 Gbps consumer and business plans. Operators like KT publicly announced 10 Gbps “Combo Internet” products and are marketing monthly plans in the multi-ten-to-hundreds USD range depending on features and guarantees. LG U+ and SK Broadband have also rolled multi-gig offers in selected areas. South Korea’s dense fiber backbone and competitive retail market accelerated the shift to true multi-gig consumer products.

3. Japan — fiber ISPs and NTT offering 10 Gbps tiers

Japanese ISPs and regional fiber operators have offered 10 Gbps class services for several years in business and, increasingly, in the residential market. NTT and other carriers introduced commercial 10 Gbps fiber services for corporate and premium residential customers; third-party ISPs resell or offer comparable 10G FTTH products. Japan’s mature fiber market and high consumer uptake of FTTH make 10 G widely available in many urban districts.

4. China — large trials and early 10G rollouts

China has been aggressive with next-generation PON (e.g., 50G-PON backbones and 10G customer tiers) and several Chinese operators and vendors were reported in 2024–2025 launching 10G services or large-scale trials. Reports in 2025 described commercial rollouts in some regions where operators provide near-10Gbps services leveraging advanced PON equipment. Because Chinese deployments are often led by China Telecom, China Unicom and vendor ecosystems, observers have noted China as one of the first countries to show 10G in the field at scale. (Coverage may initially be regional rather than uniformly national.)

5. United States — cable industry roadmap and targeted rollouts

In the U.S., CableLabs and major cable companies (Comcast, Charter, Cox) have a coordinated “10G” platform initiative focused on upgrades (DOCSIS 4.0, full-duplex and low-latency DOCSIS) to enable 10 Gbps class services over cable networks. Comcast announced multi-gig and 10G-ready initiatives and has been testing and rolling multi-gig symmetric services in parts of its footprint; however, full mass-market 10G availability varies by region and operator. In short, the U.S. has strong 10G plans and pilots in 2023–2025, with commercial expansion expected as network upgrades proceed.

How 10G is delivered — the technologies behind it

• XGS-PON / NG-PON2 / 50G-PON — fiber PON standards that can serve symmetrical 10 Gbps or aggregate multiple 10G streams. Widely used where full fiber reaches the home.

• Ethernet over fiber / dedicated fiber — business-grade Ethernet or leased-line services delivering dedicated 10G. Common for enterprises.

• DOCSIS 4.0 + CableLabs 10G — cable industry path to multi-gig/10G using upgraded coax and fiber-deep architectures (more applicable to existing HFC cable networks).

Who are the major vendors and ISPs to watch

• Cable / U.S. players: Comcast, Charter (with CableLabs coordination).

• South Korea: KT, LG U+, SK Broadband.

• Singapore: Singtel, StarHub, M1, ViewQwest.

• Japan: NTT, regional fiber ISPs and resellers.

• China: China Telecom / China Unicom / China Mobile and major PON vendors (regional rollouts and trials reported).

Who should care and why 10G matters

• Power users and households with many devices: Ultra-high-definition streaming, large home studios, multiple concurrent cloud gamers and remote-work households benefit directly.

• Small businesses and startups: Faster upload/download for backups, cloud workloads, real-time collaboration, and hosting.

• Healthcare, education, manufacturing: Low latency + high bandwidth enables telemedicine, remote labs, and advanced Industry-4.0 use cases.

• Service providers and cities: 10G enables future-proof platforms for public services and smart-city applications.

Caveats and realistic expectations

• Availability is local — even in countries that “have 10G,” the service often appears first in major cities or fiber-rich neighborhoods. Rural coverage typically lags.

• Price and value: 10G plans usually carry premium pricing (though competition in places like Singapore has driven aggressive promotions). Check whether you need full 10 Gbps or would be fine with 1–2.5 Gbps for most household use.

• Marketing vs. technical reality: “10G” as a platform goal (CableLabs) is distinct from concrete 10 Gbps retail plans; verify whether advertised “10G readiness” equals active 10Gbps service in your specific address.

How to check if 10G is available where you live 

1. Search your national regulator/telecom authority for “10G” or “10 Gbps” program updates (e.g., IMDA in Singapore).

2. Visit the websites of local ISPs (look for “10Gbps”, “10G”, “XGS-PON”, “10G FTTH”).

3. Ask neighbors or local community forums if anyone has recently ordered a 10Gbps plan — rollouts often start with a small set of early addresses.

10G is no longer just a lab slogan: by 2024–2025 we see real 10 Gbps retail products and national programs in multiple countries (notably Singapore, South Korea, Japan and regions in China) and aggressive industry programs in the U.S. driven by CableLabs and major cable operators. If you’re researching 10G for content, business planning, or shopping for a future-proof connection, focus on

(1) exact speed guarantees

(2) delivery technology (XGS-PON vs. DOCSIS)

(3) local availability and pricing. For the latest availability at your address, check local ISP plan pages or your national communications regulator.

FAQ

Q: Is 10G the same everywhere?
A: No — it can mean a full 10 Gbps retail plan (fiber), or a broader cable industry goal (CableLabs’ 10G) to reach 10-gigabit capabilities across networks. Always check the technical details.

Q: Which country was first to roll out 10G?
A: It depends on how you define “rollout.” Countries with early commercial 10Gbps retail plans include parts of Singapore, South Korea and Japan, while China reported large-scale PON rollouts in 2025; the U.S. has had 10G-class pilots and multi-gig retail rolls from cable ISPs. Dates and claims vary by region and operator.

Q: Will 10G make a difference for gaming and streaming?
A: For single-device gaming or streaming, 1–2 Gbps is often sufficient; 10G shines when many high-bandwidth devices run simultaneously, or when large uploads, cloud services and ultra-low latency are required.
