We demonstrate the passive suppression of stimulated Brillouin scattering in meter-length fiber-ring cavities through careful control of the fiber length. Experimentally we are able to demonstrate an over sixty-times increase in the Brillouin threshold of a 0.4 m fiber ring. This very simple suppression technique greatly simplifies the design of optical parametric devices based on fiber-ring cavities.
