A practical wideband analog optical fiber transmission system based on the modulation characteristics of semiconductor lasers and its structure and performance are introduced. The system’s -3dB bandwidth of 30kHz ~ 1.1GHz, nonlinear less than ± 5% of the dynamic range of not less than 40dB, peak output noise less than 5mV. With the characteristics of frequency bandwidth, large dynamic range, low output noise and strong anti-electromagnetic interference capability, it can be used for sub-nanosecond pulse signal transmission under complicated electromagnetic environment.
