DStv Course Wavelength Division Multiplexer (FTU-CWDM)


The DStv FTU-CWDM (Course Wavelength Division Multiplexer) is used when Video and Data services are combined on a single fibre. The FTU-CWDM is designed to clip onto the side of the Zinwell GTU/MS and will split the optic wavelengths between 1550nm (Video) an 1310nm / 1490 nm(Data downstream and upstream)
