Enhancement of the Operation Range of the Brillouin Analyzer Based on a Self-Sweeping Laser with Application of the Spatial Averaging with Equalizing

Key Points

• The aim is to enhance the operational range of the Brillouin analyzer for fiber optics measurements.
• Developed a Brillouin analyzer using a self-sweeping laser.
• Tested the system on a 50 km fiber line.
• Assessed performance with various processing methods including standard and correlation techniques.
• Achieved a measurement error of 1.5 MHz over a 50 km distance.
• Extended potential measurement ranges to 88 km with standard processing and 96 km with correlation processing.
