6. DWDM, WDM & CWDM Multiplexing

Connect » Real-Time Signal Transfer » Video Interfacing & Conversion » Fiber interfaces »

The ViaLite range of WDM, CWDM and DWDM products allow multiple channels, travelling in either direction, to be simultaneously combined over a single fiber.  This means signals can be multiplexed into existing infrastructure or the number of dark fibers being leased can be reduced; lowering costs.  The products come with a 5-year warranty as standard.


Wavelength Division Multiplexing (WDM)

  • Allows 2 signals to be multiplexed

  • Uni- or bi-directional

  • Utilizes 1310 and 1550nm lasers

  • Ideal for L-Band HTS and Reference or Tx/Rx in a single fiber, in satcom and diverse antennas within broadcast applications

  • High isolation between channels (90 dB RF)


Course Wavelength Division Multiplexing (CWDM)

  • 2-16 channels

  • Uni- or bi-directional

  • RF and data on a single strand of fiber

  • Reduces the number of leased fibers required – by up to 16 times

  • High isolation between channels (100 dB RF)


Dense Wavelength Division Multiplexing (CWDM)

  • 2-96  channels

  • Uni- or bi-directional

  • RF and data on a single strand of fiber

  • Reduces the number of leased fibers required – by up to 96 times

  • Can be part of ViaLite’s Long Distance Link

  • High isolation between channels


Products are available from 1310nm/1550nm WDM, ITU compliant 16 channel CWDM and up to 96 way ITU 50 or 100MHz spacing DWDM compliant Multiplexers and Demultiplexers.


High-isolation variants are available which feature exceptional adjacent optical channel isolation. These are specifically designed to complement the wide-dynamic range of ViaLite‘s fiber optic links.
