Optical transmission device and optical transmission method for transmitting a burst radio signal |
摘要 |
A light emitting section 12 outputs an optical signal having an intensity corresponding to a transmission timing signal 81, the optical signal modulated based on a radio transmission signal 82. A received photocurrent detection section 22 detects an intensity of an optical signal received by a light receiving section 21. In accordance with the detected intensity, a high frequency amplification section 23 amplifies the output signal of the light receiving section 21, and a transmission timing signal reconstruction section 24 reconstructs the transmission timing signal. The use of the light emitting section 12 outputting no optical signal in a non-transmission state and the use of the high frequency amplification section 23 outputting no signal in the non-transmission state allow noise caused in an antenna side base station 20 in the non-transmission state to be reduced.
