Dual Fiber 8CH C29-C36 DWDM OADM, EAST And West, LC/UPC, 1U Rack


QSFPTEK has designed the 8-channel DWDM OADM with drop and add wavelengths ranging from C29 to C36, which correspond to 1554.13nm to 1548.51nm. The device supports a west-to-east wavelength range of 1270nm to 1547nm / 1553nm to 1620nm in accordance with the ITU-T G.694.1 100GHZ grid, allowing for maximum capacity within the C-band range.


This is a completely passive DWDM device with 8 channels available for both drop and add functions using two fibers. The loss of waves in the west or east direction is less than 2.7dB, while the line loss in either direction is less than 5.4dB.

Quality Certifications


  • 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.
