PM CWDM

PM CWDM (Polarisation-Maintaining Coarse Wavelength Division Multiplexing) is an optical communication solution that combines Polarisation-Maintaining (PM) fibre technology with Coarse Wavelength Division Multiplexing (CWDM) and is mainly used for high-precision optical systems that are sensitive to polarisation.
