The EXFO BRT-300 Back Reflection Test Set is a bench-top optical reflectometer designed for precise measurement and analysis of back reflection in fiber networks and optical components. It delivers accurate ORL (Optical Return Loss) readings essential for signal integrity assessment, splice quality verification, and component reflectance characterization across telco, CATV, utility, and broadband infrastructure. The instrument functions as a stable continuous-wavelength light source, supporting both reflection measurements and attenuation analysis.
