    I purchased 6x 100GBASE-CWDM4 optical modules, and 3x 100G NIC cards to upgrade the rates for my storage network. The modules were well packaged and not damaged in transit, a pretty good shopping experience.

    I saw a video on YouTube about QSFPTEK product introduction, and many users said it was good, so we bought some to try to replace our current 100G QSFP28 CWDM4 modules. These modules work very well, and the parameters are the same as described on the website. It is a very cost-effective purchase.

    QSFPTEK's account manager always responded very promptly and answered my questions as much as possible. They are very professional. After browsing many 100G CWDM4, I chose them. Not only because of the competitive price, but also because of their good service and provided me with test reports, which made me very confident in their products.
