Compared to the product, QT's service is better! I am very grateful to my account manager, who always responds to my questions in a timely manner and helps me deal with after-sales issues quickly.

These modules arrived in time with a good package. During my shopping process, my sales rep. Wendy is professional. She helped me with my tender.

I bought two 100G LR4 modules to test the connection between two buildings. The transmission distance is as stated in the parameter table, which is 10KM, and the signal is very stable. I use Cisco Nexus series switches and there are no compatibility issues. If you have the same equipment as me, you can choose this module.

I came across QSFPTEK while searching on Google. Their ad caught my eye, especially with the price of $199—it was the best deal I'd seen. After checking out the product page, watching their test video, and reading their papers, I decided to give them a try. I ordered a pair of LR4 modules for testing, and they were instantly recognized by my 93600CD-GX. The throughput was solid too. Overall, it was a great shopping experience!

I purchased this for my home lab's 100G switch, and it performed flawlessly in my Cisco switch, delivering high throughput. This is the tenth QSFPTEK module I've bought, and like the others—ranging from 10G fiber/copper to 25G and 40G fiber modules—it worked seamlessly in my setup. If you're planning to use these in mission-critical applications, it might be wise to place a sample order for testing first.

I haven't installed this into my setup yet, but it feels great and looks decent. I'm looking forward to using it. If I encounter any issues in the future, I'll update this review. For now, the price seems reasonable for what you're getting.

We were in need of 100G optics to enhance our data center's network infrastructure. During my search, I came across QSFPTEK modules and, after reviewing their comprehensive datasheets, I decided to give them a try. I ordered the 100G LR4 optical modules, and they exceeded my expectations, delivering outstanding performance and ensuring seamless connectivity in our data center.

I knew qsfptek from a youtube evaluation video. it said its 10g-t module seems to work great. I needed a 100G module for an upgrade, so I bought 2 for a try. I thought it was great value at such an affordable price.
