OTDRWDM 1650

Wavelength Division Multiplexers or Demultiplexers (WDM) combine or separate optical signals with different wavelengths. They are passive optical components for uni- or bidirectional operation.
OTDR- WDM are multiplexer or demultiplexer which are used to combine or seperate signals from the telecommunication wavelength range and the OTDR monitoring wavelength range. They are standardized according to IEC 61753-089-2.
