For almost a month now, I have had these modules installed in our data center. The results have been nothing short of impressive, as they seamlessly connected our Cisco switches, establishing a rock-solid 40Gbe network. I couldn't be happier with my purchase, and the performance of these modules has exceeded my expectations. Without a doubt, I will confidently recommend them to others seeking reliable networking solutions.

I was impressed with the speedy delivery of this item, which arrived on the same day it was promised. Despite its low cost, it works perfectly with my Cisco 2960 switch, meeting all of my needs. I didn't need to configure anything, as it was truly a "plug and play" experience. Overall, I'm very satisfied with this purchase and am already considering buying more in the near future.

Last month, I made an inquiry for 20 Cisco LR4 QSFP+ transceivers, and I planned to order them in mid-January and pay with my credit card. During this period, my sales representative, Talia, provided excellent service by being attentive to my needs. She went above and beyond by offering me a discounted price, updating my account with the latest quotation, and sharing the available inventory in the US. Thanks to her efforts, the business transaction was a great success.

The modules were delivered promptly and functioned flawlessly during our pre-deployment testing. We anticipate completing the deployment by the end of the week, and I do not anticipate any challenges. Your products are exceptional, and they seem to be performing well. We are preparing for an extended trial, and during the initial setup, the QSFP modules exhibited similar characteristics to the original Cisco ones.
