The FOBER WDM (CWDM4 Channel Mux) is a high-performance optical device designed for wavelength division multiplexing (WDM) in fiber optic networks. It supports four CWDM (Coarse Wavelength Division Multiplexing) channels, enabling efficient transmission of multiple optical signals over a single fiber. This device ensures low insertion loss, high channel isolation, and excellent signal integrity. Ideal for use in long-distance telecommunications, data centers, and high-demand networking environments, the FOBER
