1550/1625nm Fused WDM Coupler (Wavelength Combiner/Splitter, Wavelength Selective Coupler) 

This 1550/1625nm fused WDM coupler is a wavelength combiner/splitter in which two input signals at 1550nm and 1625nm 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. It‘s also called wavelength selective coupler or dichroic coupler. With excellent FBT method, Lfiber designs and manufactures classical and specialty fused-fiber WDM couplers according to the customer requests. A broad range of operating wavelengths and different designs are available, please contact us to get more information. Lfiber’s fused-fiber WDMs are excellent choices and extensively used for telecommunications applications, fiber amplifiers, CATV networks, and many other industries.
