This paper reports on the performance of multi-wavelength Brillouin-Raman fiber laser exploiting an optical reflector. The ring-cavity multi-wavelength Brillouin-Raman fiber laser is based on hybrid Brillouin-Raman gain supported by SBS and SRS. The multiwavelength Brillouin-Raman fiber laser is systematically analyzed at different values of Raman pump powers, Brillouin pump powers, and categorically based on single mode fiber length, and Raman fiber length which operated from 1460 nm to 1430 nm of BP wavelengths. The optical reflector at 90% of reflectivity acts as an optical mirror is used in this structure. There are 5 channels at 1500 nm, and 1510 nm of BP wavelengths observed at Raman pump power of 30 dBm, 8 km of Raman fiber and 4 km of single mode fiber. In addition, the Raman pump power of 30 dBm is able to produce high gain value and subsequently generate a large number of channels across S-band region.
