40 Channels Passive DWDM Mux Demux, 100GHz Spacing, ITU Wavelengths C21-C60, Dual Fiber


The 40 channels DWDM Mux Demux contains a 40-channel fiber optic multiplexer and a 40-channel optical demultiplexer, supporting signal multiplexing and demultiplexing in 100GHz channel spacing DWDM systems. Based on AAWG (Athermal Arrayed Waveguide Grating) technology, the DWDM Mux Demux device combines 40-channels of 100GHz ITU wavelengths to a denser DWDM signal and separates the combined DWDM signal into 40-channels of ITU wavelengths over a pair of single-mode optical fiber. DWDM Mux Demux is fully passive and requires no power supply and temperature control. It is also easy to be installed on 1U 19-inch standard racks without moving parts, thus recognized as an ideal and cost-effective solution for point-to-point data center interconnections.

    It has been connected for a few days now, and all channel tests are normal. The price is very cheap, one-third of the well-known brands.

  • Pamela L.

    I had a really pleasant shopping experience! The engineer informed me that the 40 Ch Mux integrates MUX and DEMUX, so I placed one Mux at each end. Eventually I was able to achieve a 40-channel service transmission between the two sites.

  • Nicholas Tyler United States of America

    I am very satisfied with the 40Ch point-to-point DWDM system provided by the QSFPTEK team in October 22, so we contacted them again this year when we needed to expand 100G Ethernet business. 5.5dB typical insertion loss, completely passive, no power supply, can be inserted into the chassis.

    It was our first time to know about QSFPTEK and our first cooperation with QSFPTEK. I was impressed by this cooperation, we had very fast shipping of our order and the customer service provided us with professional service. Our test team has tested the equipment and is looking forward to its performance in our data center

  • Tristen PITTMAN United States of America

    Our data center currently intends to upgrade our DWDM muxes between the two sites. The problem we need to solve at present is that our muxes are only a few channels. By consulting the technical team of QSFPTEK, they told me that using this device can solve our problem and meet our needs for upgrading transmission channels. QSFPTEK really helped us a lot and we will choose QSFPTEK next time.
