This page on television basics tutorial covers Cable TV system basics. It explains cable TV system modules viz. cable station, multiplexer, amplifier, cable, feeders, cable TV box etc. Cable TV is the system where in TV signal is delivered to the users using coaxial cable rather than radio waves.
CATV (originally known as Community Access Television, but now commonly referred to as cable TV) is one of the most common methods of transmitting television signals to commercial buildings. Frischhertz picks up connectivity from your chosen service provider using coaxial cable to extend the signal throughout your structure.
Cable Television Distribution Network. CATV design looks simple and well-known thing at the same time has some tricky parts, like signal budget/loss calculations and interference between different frequencies.

Cable providers operate directly or lease network capacity to support customers. CATV traffic typically runs over fiber optic cableson the provider's end and over coaxial cables on the customer's end.
Most cable networks support the Data Over Cable Service Interface Specification(DOCSIS). DOCSIS defines how digital signaling over CATV lines works. The original DOCSIS 1.0 was ratified in 1997 and has been improved gradually over the years: 1. DOCSIS 1.1 (1999): Added quality of service (QoS) capability to support Voice over IP (VoIP), a technolog...
Cable internet customers must install a cable modem (typically, a DOCSIS modem) to connect their broadband routersor other devices to their internet service. Home networks also use cable gateway devices that combine the functionality of the cable modem and broadband router into a single device. Customers must subscribe to a service plan to receive ...
To hook a television to cable service, a coaxial cable is attached to the TV. The same type of cable is used to connect a cable modem to cable service. These cables use a standard F style connector, also called a CATV connector. These connectors were used with analog TV setups before cable TV existed.
Despite the similar naming, CATV is not related to Category 5 (CAT5) or other types of traditional network cables. CATV also traditionally refers to a different kind of television service than IPTV.

All rf tv systems specify cables that are nominally 75 ohms impedance. The most popular flexible coax cables being RG-59U and RG-6U for the smaller systems with RG-11U sometimes being specified on longer runs or in bigger complexes...especially for the main trunk runs.

In its concept, the technology of cable television is relatively simple. It is a system of wires and amplifiers used to gather television and radio signals from a variety of sources and deliver them to the homes in a given geographic area. It is sometimes compared with the water system of a city, which takes water from one or two primary ...
