Lfiber’s 1064/1550nm fused WDM coupler (wavelength splitter/combiner, dichroic coupler or wavelength selective coupler) is wavelength-dependent and capable of combining or separating 1064/1550nm signals. It’s based on fused-fiber and made through our state-of-the-art FBT (fused biconic taper) technology and facility. This 1064/1550nm WDM is capable of separating the two wavelengths when used in the reverse direction. It features low Insertion loss, low PDL, high stability and reliability. Related Products ↓
