A transmission system and method for transmitting broadband analog radio frequency signals using an optical transmission medium

Abstract

The invention discloses a transmission system and method for transmitting broadband analog radio frequency signals by using an optical transmission medium. The optical transmission medium of the optical transmitter box and the optical receiver box, the radio frequency signal output by the antenna is transmitted to the optical transmitter box through the cable, the optical transmitter box converts the radio frequency signal into an optical signal, and transmits the optical signal to the optical receiver box through the optical transmission medium After the optical receiving box restores the optical signal to a radio frequency signal, the radio frequency signal is transmitted to the indoor receiving device through the cable, and the indoor receiving device analyzes and processes the radio frequency signal. The present invention converts radio frequency signals into analog optical signals for signal transmission, has wide transmission bandwidth, large capacity, small dispersion, and is free from electromagnetic interference, greatly reduces the loss of signals on transmission lines, and improves the signal quality, safety and reliability of the system performance, saving construction costs.

technical field

[0001] The invention relates to the field of radio frequency signal transmission, in particular to a transmission system and method for transmitting broadband analog radio frequency signals using an optical transmission medium. Background technique

[0002] The current radio communication technology is inseparable from the transmission of radio frequency signals, regardless of radio stations, mobile phone communication base stations, satellite communication base stations and so on. Usually, in order to achieve better communication effects, the transmitting or receiving antenna of the communication base station is erected on a higher iron tower, and the communication station or receiving equipment is installed in the computer room. The equipment and the antenna need to be connected by radio frequency cables to transmit radio frequency signals.
