Dark-fibre infrastructure that gives you unrestricted connectivity between core sites, branch sites, or aggregation nodes.

Peregrine is the foundation of our dark-fibre network. Our network footprint in metro areas and smaller towns is extensive. This means that you can connect almost any site to another using the most reliable and unimpeded communications technology available today.


Peregrine lets you connect one site to another. You can use it to construct your own nationwide communications network, and in turn put your services within reach of your customers. While Peregrine is mainly for unlimited backhaul and long-haul connectivity, you can also choose our rate-monitored dark fibre service called Calypte, or provide last-mile connectivity to your customers’ sites using our short-haul unlimited dark fibre called Helios.

Terms and conditions

  1. You are responsible for providing a suitable termination facility on your premises.
  2. Costs exclude the provisioning of infrastructure between DFA’s existing dark fibre network and the your premises. This cost is for your account.
  3. DFA provides and floats the DFA cable from the DFA manhole (deemed the public domain) into the your access duct infrastructure, up to a defined customer termination point (deemed the private domain).
  4. If you require a long-haul link to be terminated at your premises, it must be terminated in a predefined long haul DFA repeater/aggregation in closest proximity to the your site.
  5. In such cases, a second, metropolitan Peregrine link must be ordered and provisioned between the DFA repeater/aggregation site and the your site.
  6. The following routes are subject to long-haul pricing:
    • Teraco Isando to Teraco Riverhorse Valley
    • Montague Gardens to Yzerfontein
    • Vanderbijlpark to Potchefstroom
  7. Regular links: The billing distance is derived by calculating the line of sight (LOS) distance between two points multiplied by a routing factor of 1.4.
  8. The R/metre cost depends on lease term selected and volume discount bracket.
  9. Long haul links: The R/metre cost depends on lease term selected and volume discount bracket.
  10. Discounts: Link volume discounts (calculated on total leased kilometres) and term discounts available depending on each client’s circumstances.
  11. The lease term and conditions for decommissioning are be stipulated in the lease agreement.
  12. You can choose to pay equal monthly rental fees over the selected lease term, or a higher, upfront, once-off payment with reduced monthly rental payments over the lease period.
  13. DFA only performs monitoring and maintenance on the main DFA fibre routes that your fibre link is provided over. No monitoring is performed on the access spur and entry point into your premises.
  14. DFA can provide permanent repairs on your access duct infrastructure on request, for your account.
  15. Diversity links are available between sites being provisioned for Peregrine. However, these links must be ordered at the same time as the primary link in order to benefit from a 50% discount over the primary link tariff.
  16. In cases where the diversity link is ordered after a primary link between two sites, the lease term on the primary link is restarted and adjusted to commence on the date of the diversity link.
  17. Downgrades of Peregrine links to Calypte Metro links are not permitted (regardless of whether they’re regular or long-haul).
  18. Penalties apply for decommissioning links before the end of their lease term. Penalties are detailed in the lease agreement.
  19. Penalties might be waived if a replacement link order is placed at the time of an early link decommissioning (for the same or higher monetary value as the decommissioned link).
  20. Replacement link orders must be “on net” and the replacement link is subject to a new full term.
  21. “On net” is defined as the distance between the customer’s access infrastructure hand hole on the boundary between the private and public domain, and the DFA route infrastructure. The maximum distance for this cannot exceed 150 meters.
  22. If a link that was operational for less than one year is decommissioned, a link discontinuation fee is payable. Additionally, a replacement link order must be placed at the time of decommissioning. Additional terms and conditions for decommissioning links are stipulated in the lease agreement.
  23. Each distinct replacement link lease term will be treated as a new lease and as such, start from a new inception date.
  24. In the case of long-haul infrastructure, links run between pre-defined repeater sites such as submarine cable landing sites and metropolitan areas. This enables connectivity between small towns and metropolitan areas.
