Optical fiber microwave frequency transmission method based on laser frequency offset-locking

An electronic device, comprising:

• a processor, a communication interface, a memory and a communication bus;
• wherein the processor, the communication interface and the memory communicate with one another through the communication bus;
• wherein the memory is configured to store a computer program;
• and
• wherein the processor is configured to execute the computer program stored in the memory to carry out an optical fiber microwave frequency transmission method, based on laser frequency offset-locking, comprising:
• generating a master laser signal and a slave laser signal by a master laser and a slave laser respectively;
• transmitting the master laser signal and the slave laser signal to a microwave frequency receiver by an optical fiber link, and locking a frequency difference between the master laser and the slave laser to a preset microwave frequency by using a laser frequency offset-locking on the master laser signal and the slave laser signal;
• receiving a return laser signal returned from the microwave frequency receiver, wherein the return laser signal comprises the master laser signal, the slave laser signal and a noise of the optical fiber link;
• and
• generating a reference signal, and adjusting the preset microwave frequency according to the reference signal and the return laser signal to compensate the noise of the optical fiber link to thereby make a microwave frequency subsequently received by the microwave frequency receiver approach a frequency of the reference signal.
