Cogent Communications operates one of the world's largest interconnected fiber-optic networks, spanning over 300 major markets globally. The company primarily serves two customer segments: corporate clients, ranging from small businesses to large enterprises, and net-centric clients, including carriers, service providers, and content creators. Its core offerings include dedicated internet access, Ethernet transport, optical wavelength services, and colocation within its data centers. By focusing exclusively on IP data transport over its own facilities, Cogent maintains a high-capacity architecture independent of traditional voice-based networks. The company has expanded its footprint significantly through strategic acquisitions, including the 2023 purchase of Sprint's wireline business from T-Mobile.
