    Compatible with my Arista equipment, 100G stable and zero packet loss, the price is only 1/3 of which I bought from another brand, it is the first choice for data centers!

    Deployed it on the Nexus 93180YC-EX switch, plug-and-play, direct system recognition, and the DDM function perfectly displayed real-time temperature and optical power data. A transmission about 65 metrs via OM4 was validated without packet loss, and the bandwidth was stable at 100Gbps, which fully met the high-speed interconnection needs between data center cabinets.

    Very easy to set up product compatibility, and QSFPTEK box together with the brand optical module, compared to the brand optical module, the price is quite a bit lower, is the right choice.

    I've been using the products in the server room for two weeks now, and everything’s working fine. My order was in stock, so I received it just four days after placing it. However, one of the modules didn't match the model I ordered, so I had to wait another three days for a replacement. Despite the small hiccup, overall, their service and products are good. They could probably improve the shipping process a bit though.

    Purchased together with OTN devices, the QSFP28 ER4 is a suitable product for long distance transmission of 40km. the engineers of QSFPTEK have provided us with similar success stories, as well as the whole list of products and their technical specifications. I would like to compliment QSFPTEK on their technical documentation, they have done a great job in this area.

    It is also very cost-effective among the modules that have been purchased, and QSFPTEK's modules are very cost-effective and affordable. It can also perform quite well in complex network environments. If you need a high bandwidth solution, then try using QSFPTEK's products.
