Dual Fiber 8CH C21-C28 DWDM Mux Demux, With Monitor, Expansion, And 1310nm Port, LC/UPC, 1U Rack Mount


The DWDM Mux Demux is commonly utilized for long-distance transmission, where wavelengths are densely packed within the C-band. With a 100GHz grid (0.8nm), up to 48 wavelengths, and with a 50GHz grid (0.4nm), up to 96 wavelengths can be accommodated. This device is versatile, as it is protocol agnostic, and can support a range of applications, including 10/1G Ethernet, SDH/SONET, FTTx, and CATV.


The QSFPTEK 8ch DWDM MUX DEMUX is designed with wavelengths spanning from C21 to C28. This device is completely passive and can be easily plugged into a 1U rack mount. Its insertion loss is 2.4dB. When connected with DWDM amplifiers and DCM equipment, the 8ch DWDM transmission system can support long-distance transmission.

Quality Testing Program


  • 1. Optimal Optical Performance
    Low optical insertion loss, zero electrical power, no temperature control requirements, and easy installation make the best-in-class operational efficiency.
  • 2. Widely Application Scenarios
    It works with colored transceivers and supports such applications as 1G/10G/25G/40G/100G Ethernet, SDH/SONET.
  • 3. Optimize Fiber Capacity with WDM Network.
    In WDM networks, a single fiber can be shared for multiple different data or services. This maximizes the usefulness of fiber and generates substantial savings.
  • 4. Quality Certifications
    Backed by CE, FCC, ROSH, ISO9001.

Questions & Answers

  • I noticed that the 40 Channels Passive DWDM Mux Demux device uses AAWG technology. What is the difference between AAWG and AWG?
    AAWG (Athermal Arrayed Waveguide Grating) remains stable across temperature variations without needing active control, making it ideal for harsh environments or where thermal control is impractical. AWG (Arrayed Waveguide Grating) lacks inherent thermal stability and may require additional thermal management. Both are used for wavelength multiplexing/demultiplexing in optical communication, but AAWG is preferred for temperature-sensitive applications.
  • I did not find the target model I need on the website, can I make a special customization?
    Sure, you can customize different channel numbers. We can provide 4/8/16/40/64, different line types with single fiber or Dual Fiber, and customize the functional ports you need. You can choose Monitor, 1310nm, and Expansion Port. Finally, you can also customize the Wavelength band you need.
  • What is the Filter Technology of the DWDM MUX DEMUX?
    We supply two types of TFF (Thin Film Filter), TAWG (Thermal Arrayed Waveguide Grating), and AAWG (Athermal Arrayed Waveguide Grating) for DWDM MUX DEMUX.

    Special mention needs to be made, the account manager, Wendy, provided very friendly service and also sent us email reminders throughout the process, telling us where is my packet. Before purchasing, he gave us very complete documents and patiently responded to any of our questions. Thanks for nice service.
