South African Telecom Main Fiber Optic Cable

Fiber and communications infrastructure knowledge brief Published 15 Mar 2021

Prepared for preliminary research by the ALFA PRO knowledge desk. Confirm optical interfaces, port or core capacity, electrical input and output, enclosure protection, thermal design and installation limits against current standards and product documentation.

South Africa's main fiber optic infrastructure is dominated by Maziv (Vumatel + Dark Fibre Africa), Openserve, and other major operators, supported by local manufacturers like YOA Cable, CBi Telecom, and M-TEC.Major Fiber Network Operators

Maziv (Vumatel + Dark Fibre Africa) is the largest fiber infrastructure operator in South Africa, covering over 2 million homes through Vumatel and approximately 14,000 km of DFA metro and enterprise fiber . The network operates on an open-access model, allowing multiple ISPs to provide services over the same infrastructure, which promotes competition and scalability . Openserve, Telkom's network division, has the widest geographic reach, including secondary towns and rural areas, with 1.454 million homes passed . Openserve focuses on both urban and less densely populated regions, making it a key player in nationwide connectivity. Other notable operators include Herotel, which targets rural and peri-urban markets, Metrofibre, Frogfoot, and Zoom Fibre, which primarily serves KwaZulu-Natal . These networks collectively support South Africa's growing FTTH market, which reached 2.47 million subscriptions by the end of 2024, reflecting a 65% year-on-year growth .

Fiber Optic Cable Manufacturers

South Africa has several leading fiber optic cable manufacturers:

  • YOA Cable: Established in 2016, YOA Cable produces a wide range of optical cables, including drop cables, micro blown cables, duct cables, armoured cables, and access building cables. They offer both single-mode and multimode solutions for local and African markets, with innovations like Fast Fusion Technology for easier installation .
  • CBi Telecom: One of Africa's largest copper and fiber optic cable manufacturers, providing customized solutions for telecom and structured cabling applications .
  • M-TEC: Founded in 1911, M-TEC manufactures aerial self-support cables, duct cables, direct buried cables, indoor cables, and micro duct cables, serving South Africa and neighboring countries .
  • Dartcom Fibre Solutions: Produces drop cables, ADSS cables, and micro cables with an annual production capacity exceeding 12,000 km, licensed under OFS Fitel, LLC .
  • AM Hengtong Africa Telecoms (AMHT): A subsidiary of Aberdare Cables, specializing in underground, aerial, and FTTH optical fiber cables, with a focus on local capacity building and technology transfer .
Network and Technology Highlights
  • Open-access model: Most major networks allow multiple ISPs to lease capacity, enabling competitive broadband services .
  • Metro and long-haul coverage: DFA and Maziv provide backbone infrastructure for enterprise and public sector connectivity .
  • FTTH growth: Urban fiber-to-the-home penetration exceeds 20% in major metros, with Vumatel alone reporting over 864,000 connected homes as of March 2025 .
  • Technological innovation: Manufacturers like YOA Cable and Dartcom implement advanced installation technologies and high-capacity fiber solutions to support growing bandwidth demands .
Summary

South Africa's fiber optic landscape is characterized by large-scale open-access networks, rapid FTTH adoption, and a strong local manufacturing base. Maziv (Vumatel + DFA) and Openserve lead in coverage and capacity, while manufacturers like YOA Cable, CBi Telecom, and M-TEC provide the essential fiber infrastructure. This combination ensures scalable, high-speed connectivity for both urban and rural areas, supporting business, residential, and enterprise broadband needs.
