Telecommunications, or telecom, encompasses computer networks, public telephone networks, radio networks, television networks and the Internet. These networks allow communication of data, text, pictures, voice and video over a long distance.
Early telecommunications transmissions used analog signals transferred over copper wires. Today, telephone and cable companies still use these same lines, though most transmissions are now in digital. Most new telecom wiring is installed with cables optimized for digital communication, like fiber-optic cables and digital phone lines.Edge distributors offer a broad spectrum of voice, data and video products from some of the leading manufacturers in the telecom industry. Products include customer premise equipment, central office equipment, and outside plant products.
