Product Description
CWDM (Coarse Wavelength Division Multiplexing) technology utilizes optical multiplexers to combine multiple wavelengths of light for signal transmission over a single fiber. At the receiving end, a demultiplexer separates the mixed signal into its constituent wavelengths, which are then directed to the corresponding receiving equipment. This technology effectively increases the capacity of fiber optic networks.
Features
- Low Insertion Loss: Ensures minimal signal attenuation.
