| 摘要 | PURPOSE:To obtain the advantages of both transmission systems by combining organically an optical fiber transmission system having a light emitting device for optical fiber and a radio transmitting system having a light emitting device for space propagation and controlling the operation of both the light emitting device. CONSTITUTION:An electric signal (a) inputted from an electric signal input terminal is modulated at a modulator 2, which outputs an electric signal (b), and the electric signal (b) is amplified at a driver 3 and applied to light emitting devices (LEDs) 4a-4c as an LED driving signal (c). The LEDs are connected in series with jumpers 12a-12c and connected in parallel with each other. The transmitter is constituted that a light (d) irradiated from the LED4a is made incident to an optical fiber 6, lights (e), (f) irradiated from the LEDs 4b, 4c are irradiated into space, the electric signal (a) is converted into an optical signal and transmitted by space propagation. | ||||||
