1310/1490nm fused WDM coupler (splitter/combiner, wavelength selective coupler or dichroic coupler) is based on fused-fiber and made through our state-of-the-art FBT (fused biconic taper) technology and facility. It’s capable of combining or separating 1310/1490nm signals. When used in the reverse direction, This 1310/1490nm fiber optic WDM can separate the two wavelengths. It features low Insertion loss, low PDL, high reliability and stability. Related Products ↓
