Transmission system and method for transmitting wide frequency band simulating radio frequency signals through optical transmission media

Abstract

The invention discloses a transmission system and method for transmitting wide frequency band simulating radio frequency signals through optical transmission media. The transmission system comprises an antenna, indoor receiving equipment, a light emission box located at an antenna end, a light receiving box at a receiving equipment side and the optical transmission media connected with the light emission box and the light receiving box, wherein radio frequency signals output by the antenna are transmitted to the light emission box through a cable, the light emission box converts the radio frequency signals into light signals and then transmits the light signals to the light receiving box through the optical transmission media, the light receiving box recovers the light signals to the radio frequency signals and then transmits the radio frequency signals to the indoor receiving equipment through a cable, and the indoor receiving equipment analyzes and processes the radio frequency signals. The radio frequency signals are converted into the simulating light signals for signal transmission, the transmission system is large in transmission bandwidth, large in capacity, small in chromatic dispersion and free of electromagnetic interference, loss of the signals on the transmission line is largely reduced, the signal quality, safety and reliability of the system are improved, and the construction cost is reduced.

Description

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. [0003] (1) The high loss of radio frequency cables is not conducive to long-distance transmission [0004] The freq...
