Competitive Network Technologies
Digital subscriber line (DSL) is a technology used by traditional telephone companies to deliver advanced services (high-speed data and sometimes video) over twisted pair copper telephone wires. It typically has lower data carrying capacity than HFC networks and data speeds can be range-limited by line lengths and quality.
Satellite television competes very well with HFC networks in delivering broadcast video services. Interactive satellite systems are less competitive in urban environments because of their large round-trip delay times, but are attractive in rural areas and other environments with insufficient or no deployed terrestrial infrastructure.
Analogous to HFC, Fiber In The Loop technology is used by telephone local exchange carriers to provide advanced services to telephone customers over the POTS local loop.
In the 2000s, telecom companies started significant deployments of Fiber to the x such as passive optical network solutions to deliver video, data and voice to compete with cable operators. These can be costly to deploy but they can provide large bandwidth capacity especially for data services.

Famous quotes containing the words competitive and/or network:
“Developing the muscles of the soul demands no competitive spirit, no killer instinct, although it may erect pain barriers that the spiritual athlete must crash through.”
—Germaine Greer (b. 1939)
“Of what use, however, is a general certainty that an insect will not walk with his head hindmost, when what you need to know is the play of inward stimulus that sends him hither and thither in a network of possible paths?”
—George Eliot [Mary Ann (or Marian)
