We demonstrate a distributed feedback (DFB) random fiber laser based on Rayleigh scattering. Amplified spontaneous emission is produced by using a segment of erbium doped fiber (EDF) pumped by 980 nm laser diode (LD). An 50km-long single-mode fiber (SMF) and a fiber bragg grate (FBG) are used as random resonate cavity and wavelength output at 1550 nm is observed which can be amplified through the erbium-doped fiber amplifier. Evaluations on the spectral evolution and power development are also performed from the results obtained.
