摘要

The method consists of using only the return band in both directions and passively without amplification, regardless of the state of development or installation of the network. The system for transferring data through the catv network comprises a head amplifier (1), a trunk amplifier (2), ancillary equipment (3) and a line extensor equipment (4) interconnected in series, said extender equipment being additionally connected to a signal diverter (5), further comprising, in series with said equipment, devices used for plc: a main head device for injecting data signals (7); a signal/repeater amplifier (9) to provide benefits to remote users; incidentally, a repeater device (10) associated with the signal amplifier, or connected to work independently, to increase the coverage; wherein, said signal amplifier/repeater device or repeater device comprises in series connected at least one platelet with an injector circuit.
