Dense WDM 1RU Optical Unit

The 9000DWDM modules are bi-directional Multiplexor/De-multiplexors which combine/separate 32 or 40 different DWDM wavelengths over a single fiber. The 9000DWDM's are housed in an Evertz 1RU unit.


  • Bi-directional mux/demux of 32 or 40 wavelengths in the C-Band DWDM spectrum (ITU-T G.694.1 compliant)
  • 0.8nm (100GHz) channel spacing
  • Passive design for any bit rate
  • Low insertion loss to conserve system power
  • High optical isolation for low crosstalk
  • SC/PC, FC/PC connector options

* 9000DWDM to be used ONLY in Single Mode Fiber applications


  • Multi-channel transport of video, audio, data, control in fiber limited applications
  • Cost reduction exercises through fewer leased fibers
  • Studio and Facility extension/expansion
  • L-band & IF Link Transport
  • STL and TSL Links
  • Signal aggregation for outdoor event coverage
  • Signal aggregation for security and monitoring
