More About Mainone Cable Company
MainOne Cable Company operates as an integrated digital infrastructure provider in West Africa, built around a private subsea fiber optic cable system that links landing points along the region’s Atlantic coast to Europe. This subsea system (subsea connectivity) is used by telecommunications operators, Internet Service Providers (ISP), content delivery networks, cloud providers, and enterprises that require international bandwidth for internet, voice, and data applications. The company’s subsea capacity is typically consumed via wavelength services, capacity leases, and IP transit offerings.
Onshore, MainOne deploys terrestrial fiber networks (metro and long-haul fiber) in major urban and intercity corridors, providing last-mile and backhaul connectivity that extends its subsea access into enterprise locations, data centers, and carrier Points of Presence (PoP). These terrestrial assets are structured into metro rings, intercity routes, and access links that support Ethernet, Multiprotocol Label Switching (MPLS) Virtual Private Network (VPN), and dedicated internet access services. Enterprise and institutional customers use these services for branch connectivity, Data Center Interconnect (DCI), cloud access, and connectivity to global networks.
The company also operates carrier-neutral data centers (data center / colocation) that provide colocation, rack space, power, cooling, and physical security for IT and network equipment. These facilities are interconnected with MainOne’s subsea and terrestrial networks, creating hubs for cloud on-ramps, content distribution, and peering between carriers and service providers. Customers deploy equipment in these data centers for hosting applications, storage, Disaster Recovery (DR), and as regional presence points for latency-sensitive services targeting West African users.
On top of its connectivity and colocation platforms, MainOne offers IP services and managed solutions such as IP transit, enterprise internet access, virtual private networks, and value-added managed network services (IP services / enterprise connectivity). These are commonly used by banks, multinationals, government agencies, and digital service providers that require predictable bandwidth, Service Level Agreements (SLAs), and support for critical applications across multiple sites and countries.
MainOne’s cloud-related portfolio (cloud and managed services) builds on its data centers and network footprint to provide hosting, private and hybrid cloud enablement, and connectivity into global public cloud platforms. This positioning places the company in marketplace categories including subsea cable operators, metro and long-haul fiber providers, carrier-neutral data centers, IP transit and enterprise connectivity providers, and cloud and managed infrastructure services focused on West African markets.
