Microstructured Multi-core Sensing Fiber (Hydrogen Corrosion Resistant, Pure Quartz, Mode Field Diameter @ 1550nm: 3μm

Compared to conventional step-index optical fibers, specially designed microstructured optical fibers offer ultra-low loss, improved optical modes, hydrogen corrosion resistance, and a single-material composition (pure silica, without doping). These superior characteristics significantly enhance the sensitivity of distributed optical fiber sensing systems, system stability, spatial measurement accuracy, and fiber lifespan. The fiber structure and parameters can be customized for production.
