Fiberdyne Labs, Inc. Dense Wave Division Multiplexers (DWDMs)

Dense Wave Division Multiplexers (DWDMs)

    Dense WDM (DWDMs) provide the ability to expand fiber capacity by allowing you to combine or separate multiple wavelength on a single fiber. DWDM's follow the ITU Grid channel spacing standards and are available at 50GHz spacing (96 Channels max), 100GHZ spacing (48 channels max), and 200GHz 
    (20 Channels max) spacing.


    Custom configurations are available-- let us know what you need!

    Fiberdyne Labs offers Dense Wave Division Multiplexer modules in a wide variety of formats. While Fiberdyne offers some models as "standard," we will also produce customized DWDM modules. Customization can include the number and selection of DWDM channels. Additionally, modules may include tap/monitoring capability and variable attenuation. These modules may be a number of standard form factors, such as LGX, EIA-standard 19/23-inch rackmount, wallmount, and standalone filters.

    DWDM is a proven technology, which offers flat channel bandwidth, flexible channel configuration, low insertion loss and high isolation. Fiberdyne Labs modules can be optically daisy-chained, to provide additional channels as bandwidth needs grow. Modules are available on the C & L bands, ITU 100GHz grid at channel spacing of 100GHz or 200GHz.

  • - Epoxy-Free Optical Path
  • - Low Insertion Loss
  • - High Return Loss
  • - ITU Standard Channels

  • - Telecommunications
  • - Local Area Networks
  • - CATV Fiber Optic Links

    Conceptual Usage:
    The schematic below shows how a DWDM module, with attenuation and splitter/tap, may operate. This configuration includes an "Upgrade" port. For future expansion, the upgrade port is connected to new modules, adding new channels to an existing link. This can be done without interruption of the existing links.

DWDM Drawing

  • - Number of channels: 1 - 40 channels in one module
  • - Single or multi-fiber solutions available
    •     - Single-fiber: transmit and receive signals on one fiber
    •     - Dual-fiber: transmit and receive signals on separate fibers
  • - 100-GHz or 200-GHz channel spacing
  • - Module formats compatible with LGX, 19/23-inch rackmount
  • - Connectors: FC, LC, SC, ST
  • - Customization available:
    •     - Additional filter options available, such as "Red/Blue" mux/demux filtering
    •     - Unique channel selections or spacings (i.e. skip channel numbers)
  • - Cisco-compatible modules - mimic the function of Cisco 15216-series modules
