Kaapelitelevisioverkot, often referred to as cable TV networks, are a system for distributing television and internet services to subscribers through a coaxial or fiber-optic cable infrastructure. These networks were initially developed to provide improved television reception in areas where terrestrial signals were weak or unavailable. Over time, their capabilities have expanded significantly to include high-speed broadband internet access and digital telephone services, creating a bundled triple-play offering for many consumers.

The infrastructure of a cable TV network typically begins at a headend, which receives signals from various sources, including satellite dishes, terrestrial antennas, and direct fiber feeds. These signals are then processed, converted to the appropriate frequencies, and amplified before being distributed through a network of trunk lines and feeder cables to individual homes and businesses. Early cable TV networks utilized coaxial cable exclusively, but modern systems often incorporate fiber-optic cables for greater bandwidth and signal integrity, especially for the trunk lines, with coaxial cable used for the final drop to the customer premises.

The technology allows for a large number of channels to be broadcast simultaneously, and digital transmission has enabled the delivery of high-definition programming and a wider range of interactive services. The deployment and maintenance of these networks require significant investment in infrastructure and technology. While initially dominant, cable TV networks now face competition from other delivery methods such as satellite television, terrestrial digital broadcasting, and increasingly, internet-based streaming services.
