Communication signal output control method and device and output equipment

Abstract

The invention discloses a communication signal output control method. The method comprises the following steps: acquiring the length of a communication line; receiving an input signal amplitude, and calculating a target output signal amplitude according to the length of the communication line and the input signal amplitude; wherein the target output signal amplitude is in positive correlation with the length of the communication line; and controlling a signal output unit to output a communication signal satisfying the target output signal amplitude. The invention further discloses a corresponding communication signal output control device and communication signal output equipment. By implementing the invention, the problem that the intensity of the communication signal received by the signal receiving end changes along with the change of the length of the communication line in the prior art can be solved, and the intensity and power of the communication signal received by the receiving end are controlled within a certain range, so that the communication signal quality is effectively improved, and the communication reliability is improved; and the compatibility of communication products is effectively ensured.

Description

Technical field[0001]The present invention relates to the field of communication technologies, and more particularly to an output control method, apparatus, and output device of a communication signal.Background technique[0002]Communication technology in modern communication fields include fiber optic communication and network cable communication. In order to meet the different signal transmission distances, some devices that extend communication line transmission lengths are typically employed to further improve the transmission distance of the communication signal. For example, for fiber optic communication technologies, the length of fiber optic line transmission can be further extended by the fiber repeater.[0003]However, in the process of carrying out the present invention, the inventors have found that the prior art has at least the problem: the feedback control of the communication signal output device is only from the amplitude of its input signal, which makes the output pow...
