Ibiúna is a small town with 75,000 inhabitants, located 43 miles from the state capital of São Paulo, Brazil. Its economy relies primarily on agriculture, especially vegetables. By the end of 2020, only one mobile operator covered the rural area. Internet access was possible with satellite services, such as Hughes. The countryside reality changed when a small internet service provider (ISP) deployed fiber optics and began offering fixed broadband to houses and farms.

Ibiúna exemplifies the reality of the fixed network in Brazil, where almost 22,000 ISPs are responsible for bringing internet services throughout the country, pushing the fiber expansion.

Together, ISPs correspond to more than half of fixed broadband connections in Brazil – which totaled 53.7 million in September – and are responsible for two-thirds of fixed network investments. The large number of small ISPs, meanwhile, differentiates Brazil from the rest of Latin America (LATAM).

The region has seen a boost in fiber optic (FTTH) deployments, mostly coinciding with the COVID-19 pandemic’s increased demand for connectivity. As an average for the entire region, S&P Market Intelligence calculates that residential fixed broadband penetration reached 54.8% of LATAM households at the end of 2024.

Despite this, the fixed network landscape in the region is marked by fragmentation, asymmetry in infrastructure quality, and strong regional disparities.

Uneven growth across the region

Across Latin America, the scenario varies. IDC states that, while fiber rollout in Brazil is accelerating, with aggressive fiber deployment from ISPs driving high FTTH penetration, especially in secondary cities and underserved areas such as Mexico, Chile, and Colombia, coverage is still uneven, with urban centers prioritized over rural regions.

In Argentina and Peru, fiber expansion is slower, often hindered by regulatory, economic, or logistical challenges. Central America is still dominated by legacy technologies, with limited fiber rollout.

“Brazil’s ISP model has not been fully replicated elsewhere due to market fragmentation, investment limitations, and regulatory challenges, though in Peru and Ecuador, ISPs are expanding fiber coverage, but rural areas remain underserved”, noted Luciano Saboia, director of Research and Consulting for the Telecommunications segment at IDC for Latin America.

LATAM countries have differences between them, either in terms of population size, urban density, geography, and economics. While Brazil leads in fiber penetration due to aggressive ISP deployments, other countries still rely heavily on legacy copper or hybrid networks.

S&P Market Intelligence notes that Uruguay, the region's smallest nation with 3.5 million inhabitants, ended 2024 with the highest level of fixed broadband penetration at a little over 88%, while the largest and most populous country in the region, Brazil, posted a fixed broadband penetration of around 61% in 2024. Argentina and Chile, both at around 73%, follow relatively close behind.

“We see room for continued expansion over the following years, with FTTH, which already reached 62% market share in terms of connections in 2024, increasing that market share in the future,” said Tomas Sarmiento, research specialist at S&P Market Intelligence.

Omdia highlights Uruguay and Chile as the most developed LATAM countries in fiber adoption, though there are key differences between the two. Uruguay’s government-owned telecommunications company, Antel, has deployed fiber throughout the country, while Chile has a more open economy.

Argentina has boosted its fiber optics infrastructure recently, but the country remains stronger in cable. Also, ISPs are growing, with around 1,500 small firms in total. The country lags behind Brazil, where 56% of broadband was provided by small operators as of last June, according to Anatel, Brazil's national telecommunications agency.

“The fiber optics market is, among telecom services, the one that grows the most in the region and the most promising one,” said Ari Lopes, Practice Leader in Omdia's Service Provider Markets Americas team.

Lopes stated that Uruguay, Chile, Brazil, and Mexico are fast-growing, imposing an annual rate between 10% and 15%. In smaller and less developed countries such as Colombia, Peru, and Ecuador, fiber is heating up at rates that double that, reaching 25% to 30% per year.

By the second quarter of 2025, Latin America had 87.8 million fiber optic connections, about two-thirds of the region’s 133.4 million total fixed broadband lines, according to Omdia.

“The region is transitioning from traditional fixed voice and DSL to FTTH and FTTx, but the pace varies significantly”, notes IDC’s Saboia. The push toward cloud, AI, and digital services is accelerating investments in data center infrastructure and fiber-to-the-premises (FTTP).

Brazil, Mexico, Chile, and Colombia stand out as the most mature countries in Latin America’s digital infrastructure landscape, Saboia noted, adding that Brazil leads in fiber deployment and data center investments, with its vibrant ecosystem of ISPs and hyperscale cloud providers.

“Mexico and Chile have made significant progress in fiber penetration and cloud adoption, while Colombia is rapidly catching up, especially in urban areas. These countries benefit from regulatory support, strong investment from both local and global players, and a growing demand for advanced digital services,” the IDC director said.

Ignacio Perrone, research director at Frost, added that network maturity level in the region is high, but it’s necessary to separate residential to corporate access, as video, cloud, and AI pushed development and huge investments into the fiber segment, especially in building out network backbones.

Rising competition and consolidation

The aggressive ISP coverage in Brazil reached areas not focused on by the big three telecoms groups: Telefonica’s Vivo, Telecom Italia’s Tim, and America Movil’s Claro. Overall it helped increase competition, as the considerable small ISP presence reduces the market hegemony of the large operators. In contrast, mobile telephony remains dominated by the big three.

Saboia classified Brazil and Chile as highly competitive markets, with active infrastructure sharing and numerous ISPs helping to foster price competition and service innovation. Meanwhile Mexico and Colombia, where a few large players dominate but new entrants and regulatory reforms are increasing competition, are instead classified as moderately competitive.

Saboia pointed to Argentina, Peru, and Central American countries as the least competitive, due to market concentration, regulatory barriers, and limited investment slowing progress.

“I don't think we'll see an increase in competition. I think it's more of a moment of stability, tending towards consolidation for all those small players,” emphasized Perrone from Frost.

Indeed, the Brazilian ISP market has already seen a merger and acquisition movement. “For all those small ISPs, a wave of renewal and investment is coming, and it can be very complicated, but not for everyone, of course. I think we're going to see more and more consolidation in the sector”, Perrone noted.

In Brazil, the competitive environment, as shaped by both large telcos and the dynamic ISP ecosystem, has also led to consolidation and infrastructure sharing becoming increasingly common to optimize costs and expand coverage.

As a consequence, companies emerged operating in the fixed network sector as neutral players, such as V.tal, FiBrasil, and I-Systems. These challengers build and manage shared infrastructure, leasing it to multiple internet service providers (ISPs) and mobile operators.

“ISPs have changed the market in Brazil and Latin America. They are also responsible for the creation of fiber optic wholesale companies, because the large companies saw they were losing market share, so they separated their fiber optic portfolio, attracted investors, and brought in partners to make investments,” Omdia’s Lopes said.

Fiber as the foundation for LATAM’s digital future

Following the network expansion, LATAM players face an aggressive pricing strategy both to gain and retain clients. When evaluating prices versus speed, broadband offerings in the region have increasingly higher average speeds, while average prices remain flat.

Therefore, as they can't raise prices, providers are adding value to their offerings to monetize their network investments. These value adds include video services (pay TV or streaming), fiber-to-the-room (FTTR), Wi-Fi Mesh, security surveillance cameras, among others.

Frost’s Ignacio Perrone also noted that keeping profitability as ARPU decreases is a challenge and makes it difficult to justify new investments.

"Fiber optic delivers a better service for customers, potentially more speed, lower latency – a lot of advantages – and for the service provider too, as it is easier to maintain. The problem is that expanding the network still has the same cost as before”, Perrone said.

As for corporate offerings, several initiatives are trending across LATAM. IDC’s Saboia points out examples such as enterprise cloud migration, with businesses moving workloads to hybrid and multicloud environments, driving demand for high-capacity data center connectivity. In addition to AI and the Internet of Things (IoT), regional sectors like manufacturing, mining, and agriculture are adopting private LTE/5G networks for automation, remote monitoring, and predictive analytics.

Fiber is also paving the way for reliable home broadband to support remote work, online learning, and telehealth. In terms of smart cities, projects are being seen in Brazil, Mexico, and Colombia, through support of traffic management, public safety, and digital government services.

In terms of technology, the most used and scaled services include FTTH/FTTx, especially in Brazil, Chile, and Colombia. Gigabit passive optical network (GPON) is widely adopted for fiber access. Technologies that are still evolving include 10 Gb/s XGS-PON fiber, AI-powered network management, and full-scale smart home/IoT integration. FWA is growing, but isn't yet a universal substitute for fiber in all markets.

Open RAN and network slicing are in early-stage trials, while AI-driven network automation is limited to Tier 1 operators.

A vital, transformative shift

As fiber optic expansion in LATAM progresses and successful deployment models emerge, providers must balance profitability and ARPU against the required investment needed to maintain pace and an even market.

Fiber's role is more than just connectivity; it serves as a foundation for all digital services and is key to any country's digital strategy as a critical enabler of economic development and technological advancement.

Extending coverage gaps will require further investment and support, but it is vital to positioning LATAM for sustained economic development as the world continues to adopt digital.
