    I have made many purchases at QSFPTEK and Talia has provided me with a lot of help. Each time, the documentation is complete, and after receiving the goods, I also conducted tests. The parameters obtained are consistent with the website description. QSFPTEK's quality control is done very well.

    Upgrading my network to 100G, the network transition went very smoothly and the rate and reliability of my network has increased dramatically, so if you're looking to upgrade your network to cope with the bandwidth of the future, then upgrade to 100G with QSFPTEK!

    We ordered 100 QSFP28 ER4 modules, which are very compatible with our several Cisco Nexus-N9K-C92304QC switches. It can be seen that QSFPTEK's module quality control is very good. It can establish a stable connection over a long distance of 40 kilometers, and its performance is also excellent enough to meet our needs for long-distance transmission.

    The 40KM QSFP28 ER4 module I purchased can reach 40km in real life, something different from our previous purchase on the website is that QSFPTEK's product delivery is very fast and beyond our expectation!

    All in all great value for nice-built 100G modules at such a good price, especially compared to OEMs. I have used OEM optics before but see no difference in performance.

    Used these at home and work, and they have proven to be quality. They integrate seamlessly with my Cisco and Ubiquiti equipment. This was my fourth QSFPTEK optic. I've also used their 10G, 25G, and 40G transceivers, all of which have worked well.
