Lfiber’s classical 1310/1550nm fused WDM coupler is a wavelength selective coupler (or wavelength combiner/splitter) in which two inputs at 1310nm and 1550nm bands from the two input ports are combined at one output port. When used in the reverse direction, it’s capable of separating the two wavelengths. This 1310/1550nm WDM is based on fused-fiber and made through our state-of-the-art fused biconic taper (FBT) technology and facility. It features low Insertion loss, low PDL, high stability and reliability. Related Products
