Fiber Encircled Flux (EF) is an important physical quantity in multimode fiber transmission, reflecting the distribution of the optical signal in the fiber and the transmission efficiency. By accurately measuring and analyzing the fiber encircled flux, the performance of fiber transmission and fiber sensors can be evaluated, thereby optimizing the fiber structure and parameters, improving sensing sensitivity and transmission stability. JW8630 is a high-performance encircled flux meter designed specifically for multimode fiber systems. The device integrates focal end-face inspection, adjustable attenuation and real-time analysis functions into one, comprehensively optimizing optical throughput and modal conditions, and is suitable for various scenarios such as fiber coupling, device characterization testing and standard consistency verification. Encircled flux measurement can be performed by connecting a light source and fiber patch cord to the fiber encircled flux tester to measure the fiber modal launch condition, providing injection conditions for real-time measurement of fiber modes, ensuring the performance and reliability of fiber communication systems while optimizing fiber applications and design, and is very suitable for multimode fiber modal analysis.
