Openserve

What Openserve does

Openserve is the wholesale fibre infrastructure subsidiary of South African telecom operator Telkom Group, established in 2015 and headquartered in Johannesburg (with operating base in Centurion). It operates a national fibre optic network exceeding 170,000km, providing carrier-grade connectivity to Internet Service Providers (ISPs), enterprise customers, and, via its ISP partners, residential consumers. The company's stated focus is on last-mile fibre deployment, digital inclusion in underserved communities, and supporting next-generation workloads such as AI through edge data centre capabilities.

The product portfolio centres on wholesale fibre infrastructure: Fibre-to-the-Home (FTTH) services with industry-leading conversion rates of approximately one in two homes passed, the newly launched Fibre-to-the-Room (FTTR) solution developed with Huawei SA for gigabit in-building connectivity, and a planned rural and peri-urban expansion initiative. Technology differentiators include standardised use of AFL FlexScan OTDR for network deployment and testing (following the OpenReach playbook), edge computing infrastructure for AI-adjacent workloads, and ORAN-aligned radio integration via Oran Development Corporation for AI in radio networks.

Commercially, Openserve operates a B2B wholesale / channel-partner model: it sells fibre connectivity on a subscription-recurring basis to ISPs (e.g., Webafrica) and enterprise customers, while Telkom Group's broader data revenue now represents approximately 60% of group revenue. Openserve posted 2.2% revenue growth across three consecutive positive quarters, suggesting data growth is outpacing the structural decline of legacy copper. Distribution is anchored on long-term ISP partnerships supplemented by direct enterprise sales, with public positioning reinforced through participation in AfricaCom and the Wired4Women Awards sponsorship programme.
