830/1310nm Single Mode Three Port WDM

Three-port wavelength division multiplexer, namely FWDM, is also called 3-wavelength wavelength division multiplexer, also known as three-wavelength filter wavelength division multiplexer. Three-wavelength wavelength division multiplexer refers to a wavelength division multiplexing device that fixes three specific wavelengths (1310/1490/1550). Because wavelength division multiplexers with other wavelengths are more widely used, the industry directly calls 3-wavelength wavelength division multiplexers FWDM. F stands for Filter, which means filtering. FWDM is filter-type wavelength division multiplexing. In the optical fiber communication network, this three-port wavelength division multiplexer can be used to achieve two-way transmission of voice, video, and data. The three-port wavelength division multiplexer adopts the packaging that combines the filter principle and the collimator principle, and can customize any three wavelengths. The so-called FWDM directly refers to the wavelength division multiplexer with three wavelengths of 1310/1490/1550. All devices provided by Idealphotonics have undergone 24-hour high and low temperature cycle and drop tests, and the product quality is reliable and stable.
