Broadband amplifiers
One of the key elements in coaxial cable networks is a broadband amplifier. Its main task is the amplification of RF signals to obtain a signal level necessary for signal distribution. Modern broadband amplifiers can transmit signals in the forward (to subscribers) and return (from subscribers to a headend) paths. Thanks to this feature it is possible to provide subscribers with Triple Play services (TV, Internet and telephony).
A coaxial cable network can be divided into two areas for which different types of broadband amplifiers are used:
Broadband amplifiers have the following technical parameters and features:
VECTOR is the leading European manufacturer of broadband amplifiers. We offer a wide portfolio in this area. Additionally, we can offer solutions which meet the customer's needs. Beside broadband amplifiers, VECTOR offers cable operators turn-key infrastructure solutions, starting with consulting in this area, network design, installation services, network measuremenmts and audits, ending with equipment delivery for HFC network deployment.
A coaxial cable network can be divided into two areas for which different types of broadband amplifiers are used:
- distribution network, which distributes the signal to building networks. Distribution amplifiers are used in this area
- building network, which distributes the signal to subscribers. Building amplifiers are used in this area
