Transition Networks CWDM products uses a passive technology that allows for any protocol to be transported over the fiber link, as long as it is at a specific wavelength. Transition Networks’ WDM Mux/Demux and Add/Drop Mux can provide a simple and affordable method to maximize existing fiber capacity with little or no increased cost.


  • Increase bandwidth on existing fiber infrastructure
  • Alleviate fiber exhaustion
  • Transmit multiple protocols over an existing duplex fiber link by combining the fiber outputs of multiple media converters
  • Provide scalable bandwidth of up to 10 Gbps per channel over existing fiber links
  • Plug-and-Play, no configuration of CWDM components
  • Use existing standard optical ports on switches and routers
    • Utilize Optical Line Converter as transponder
  • 1 RU rack mountable chassis to hold 2 CWDM modules
