Paper Abstract

The influence of the fiber length and input power on pulse light stimulated Brillouin scattering effect was investigated. Laser with the wavelength 1550nm emitted a continuous optical input electro-optic modulator, and then is modulated into pulsed light. The pulsed signal is provided by the signal generator, pulse width 200ns, repetition frequency 2 KHz. The results show that the threshold of pulse light stimulated Brillouin scattering is 3.1dBm with the 25 Km single-mode optical fiber, and the light intensity of stimulated Brillouin scattering starts to grow slowly when the pump power is beyond 8.1dBm. It can be seen that Brillouin Stokes power increases with the growth of fiber length, but when the fiber is longer than 31km, the Brillouin Stokes power reaches saturation.
