What is the difference between FTTH and FTTB fiber connections?
Quick Answer
FTTH (Fiber to the Home) runs a dedicated fiber strand directly into an individual residential unit, while FTTB (Fiber to the Building) terminates fiber at a building distribution point and uses existing copper or new ethernet cabling for the final connection to individual units. FTTH delivers the highest performance, while FTTB is often more practical in multi-tenant buildings.
Detailed Explanation
Fiber to the Home (FTTH) provides a dedicated optical path from the network operator's central office or point of presence all the way into the subscriber's premises, where an Optical Network Terminal (ONT) converts the optical signal to an ethernet connection. Because each subscriber has their own dedicated fiber strand or wavelength, FTTH delivers symmetrical speeds that do not degrade during peak usage periods. This architecture is the preferred deployment model for greenfield residential estates and new commercial developments in South Africa, where all infrastructure can be installed during construction at relatively low incremental cost.
Fiber to the Building (FTTB) terminates the service provider's fiber at a central distribution point within or adjacent to the building, such as a basement telecommunications room or a street-level optical distribution frame. From this point, connectivity to individual units is achieved using the building's existing copper telephone pairs, new category cabling, or short fiber runs. FTTB is the dominant model for retrofitting fiber connectivity into older apartment blocks, office parks, and mixed-use developments where running individual fiber strands to every unit would require extensive civil works and significant disruption to occupants.
In the context of South Africa's accelerating fiber rollout, network operators including Vumatel, Openserve, and Metrofiber predominantly deploy FTTH in new residential areas, while operators serving the enterprise and multi-dwelling market often use FTTB architectures. For business tenants in existing commercial buildings, the distinction matters because FTTB speeds may be shared across multiple tenants at the building distribution point if bandwidth provisioning is not carefully managed. CT Communications designs and installs both FTTH and FTTB termination infrastructure, including the internal structured cabling that connects the building distribution point to individual tenant demarcation points.
