Wireless optical transmission device for bidirectional radio frequency signals

Abstract

The invention relates to the technical field of communication, and discloses a wireless optical transmission device for bidirectional radio frequency signals, which comprises a transceiving separation module, an electro-optical conversion module and a photoelectric conversion module, a first port of the transmit-receive separation module is connected with a radio frequency signal source, a second port of the transmit-receive separation module is connected with the electro-optical conversion module, and a third port of the transmit-receive separation module is connected with the photoelectric conversion module; a radio frequency signal enters the transmit-receive separation module through the first port, leaves the transmit-receive separation module through the second port and enters the electro-optical conversion module. A signal output by the photoelectric conversion module enters the transmit-receive separation module through the third port and leaves the transmit-receive separation module through the first port. According to the invention, radio frequency signals in two receiving and transmitting directions are separated through the receiving and transmitting separation module and are respectively connected with optical paths in different directions, so that two-way real-time communication with fusion of radio frequency communication and optical communication is realized, and the device can be used in combination with radio frequency receiving and transmitting equipment to transmit radio frequency signals in any frequency band.

[0002] With the increasing shortage of spectrum resources in the radio frequency communication range, manufacturers and researchers are turning their attention to the field of optical communication with rich spectrum resources. However, the optical communication standards are not complete, and low-cost and widely distributed WiFi base stations have always hindered optical communication. commercial use of the system

In addition, because the optical communication link built by the researchers is different from the existing base station communication protocol, the experimental system can only be tested offline

[0003] In the existing fusion scheme of radio frequency communication and optical communication, the radio frequency transceiver equipment needs to have at least two radio frequency ports, and multiple radio frequency ports need to work together, so the requirements for the radio frequency transceiver equipment are relatively high; and in the existing fusion scheme Only one-way, offline communication can be realized, but two-way, real-time communication cannot be realized
