Globally, the top 200 dark fiber and lit fiber providers deliver connectivity services to businesses through fiber optic networks that span millions of miles around the world. These business-to-business (B2B) fiber companies connect various types of facilities, from office buildings to cell towers, and data centers to stadiums. Commonly referred to as dark fiber and lit fiber providers, these companies are also known as carriers of carriers. They offer solutions under various terminologies, including unlit fiber, wholesale fiber, bulk fiber, carrier fiber, enterprise fiber, and business fiber.
In total, the 10 most prominent dark fiber and lit fiber providers in the world, including Lumen, Zayo, Colt Technology Services, Cogent, EXA Infrastructure, Arelion, Telecom Italia (TIM) / Sparkle, NTT, AT&T, and Verizon, collectively operate over 4 million route miles of fiber optic network.
Dgtl Infra has categorized the largest 200 dark fiber and lit fiber providers in the world into 6 groups based on their geographic operating region and several measurable market share factors, including: fiber network size (route miles and strand miles), number of on-net buildings (including data centers and cell towers), and revenue in U.S. Dollars, among others. Our list encompasses both independent dark fiber and lit fiber providers as well as telecommunications companies that offer these services as part of their broader business.
Subsequently, we delve deeper into the businesses and networks of 30 notable dark fiber and lit fiber providers, particularly focusing on companies operating in the United States, Europe, and Latin America. This analysis includes information about the length of their network in fiber route miles, the geographical areas where they serve their customers, and the type of provider they are (dark, lit, or a combination of both).
Top 200 Dark Fiber and Lit Fiber Providers in the World
The top 200 dark fiber and lit fiber providers in the world are categorized into the following geographic segments: multiple regions, North America, Europe, Asia Pacific, Latin America, and the Middle East and Africa.
It is important to note that Dgtl Infra’s list focuses on facilities-based providers of fiber networks, who own and operate their own physical infrastructure, as opposed to relying on leasing or reselling capacity from other network owners to deliver services. Additionally, we exclude companies operating primarily in China and Russia, as well as businesses that mainly own subsea cables, as opposed to terrestrial dark fiber and lit fiber, which our list focuses on.
