This QSFP28 2km module product is very suitable for our distance, just to fill the gap in our program, it is worth mentioning that in QSFPTEK for us to provide free shipping, at the same time, the package shipping speed is also very fast.

Received the modules in just three days. helped our production a lot, our switch connects seamlessly with this module, same quality as my previous brand modules, very reliable.

Before shipment, QSFPTEK tested each module for us and these test reports are straightforward. Also provided us with User Guide and datasheet some. For those of us who don't know the product particularly well, we can understand the product very quickly.

Using this 100GBASE-FR module is great, along with this order was also purchased a 400G XDR4 module. I would say for the 100G normal module it is worth the price, in the 400G module, which has not been used yet, only tested, these modules have all worked seamlessly with my switches and no issues have occurred.

Great company with excellent service! They helped me choose the right modules and were very friendly and polite.

Bought a pair of these single lambda modules under Wendy's recommendation. They look well assembled in an intact package without any damage. I asked for no labels because I needed to put my factory logo on it, and they did. Already integrated them into my setup and for now I haven't noticed any problems. If it does, I'll come back here to alert you guys. After all, no one wants to delay the project.
