Exfo BRT-320A Return Loss Test Set

The EXFO BRT-320A Return Loss Test Set is a precision optical measurement instrument designed for characterizing the reflective properties of fiber optic components and links. This specialized test set provides accurate measurement of optical return loss (ORL) across a wide dynamic range, enabling technicians and engineers to verify the quality of fiber terminations, connectors, and splices. The unit operates at 1310nm and 1550nm wavelengths, covering the most common optical communication bands. Its high-resolution detection system can identify even minor reflections that could degrade system performance in high-speed or long-haul optical networks. The BRT-320A features both continuous wave and modulated measurement modes, allowing for comprehensive characterization under different operating conditions. The instrument includes advanced averaging and filtering functions to improve measurement stability in noisy environments. Its compact, portable design makes it suitable for both laboratory and field use, while the intuitive interface simplifies operation. The test set supports multiple measurement units including dB, dBm, and linear power, with results displayable in both numerical and graphical formats. Comprehensive data logging capabilities enable trend analysis and documentation for quality assurance purposes. The BRT-320A is particularly valuable for testing optical distribution networks (ODNs) in FTTH deployments, where multiple connection points can contribute to accumulated return loss that may impact system performance.
