DWDM, WDM & CWDM Multiplexing

The ViaLite range of WDM, CWDM and DWDM products allow multiple channels, traveling 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
  • Utilises 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 (DWDM)

  • 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


Product Inquiry
DWDM, WDM & CWDM Multiplexing

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.

The WDM – 2 channel Duplexers are available in either pigtail or plug-in module format, allowing original equipment manufacturers to build them into larger systems or for them to be rack mounted in a ViaLite chassis with other modules.

The CWDM – 4 and 8 channel systems are available in compact 1U high 19″ rack format.

The DWDM – 4, 8 and 16-way systems are available in compact 1U high 19″ rack format. Up to 96 channels are available.
