Title:
COMMUNICATION CONTROL DEVICE, COMMUNICATION CONTROL SYSTEM, AND COMMUNICATION CONTROL METHOD
Document Type and Number:
Japanese Patent JP2022124168
Kind Code:
A
Abstract:
To provide a communication control device and a communication control method that stabilize a communication system using optical fiber radio.SOLUTION: An optical detector 201 receives an optical signal including a reference signal having a predetermined signal strength and a communication signal and converts it into an electric signal. An amplifier 202 amplifies the electric signal generated by the optical detector 201. A gain adjustment unit 203 adjusts gain of the electric signal amplified by the amplifier 202. An antenna 207 outputs the communication signal included in the electric signal whose gain has been adjusted by the gain adjustment unit 203. A bandpass filter 206 acquires the reference signal based on the optical signal. A control unit 205 measures signal strength of the reference signal, compares the measured signal strength with the predetermined signal strength, and controls the gain adjustment unit 203 based on a comparison result.SELECTED DRAWING: Figure 2
