A multiple wavelength Brillouin/erbium fiber laser that generated six output channels at maximum pumping powers is presented. The laser is configured to allow uni-directional flow of both the Brillouin pump and the Brillouin Stokes signals through the Erbium doped fiber amplifier. Stability studies on the generated channels buttressed the fact that the proposed laser has met the stringent requirement of power stability and precision channel spacing in order to be deployed to support the DWDM systems. At Brillouin pump power of 2 mW and 1480 nm laser pump power of 130 mW, the wavelength of the first channel has not shifted over an observation period of one hour. The other channels recorded average wavelength shifts of 0.002 nm. Over the same observation period, the first channel records a power fluctuations of only 0.03 dB.
