Optical transmission device and optical transmission method for transmitting a burst radio signal |
摘要 |
<p>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. <IMAGE></p> |
