Fast shipping and delivery, I will keep a close eye on these type of products.

We wanted a higher speed network system and needed to choose some transceivers, we didn't need a long transmission distance, so this type was just right for us. They proved to have excellent connectivity, and all metrics were within normal limits.

We've communicate with several companies before and they were not able to offer enough amount we expected. But FS.com did it. Would like to do business again with them.

Generally, their modules can be easily picked up by my devices. This time is no exception. We soon finished the connection and gave it a series of tests by ourselves. Happily, they perform quite well. Then we are really assured. Now we have used it for almost two months. Everything goes well.

The models came brand new, wrapped nicely, no damage. Using them successfully in our switches. Just a few seconds later, switches were linked and started transferring data over SMF. Overall, I'm very pleased with the purchase.

I have inquired several vendors about the 800G QSFP-DD optical modules, but their product delivery time is too long to satisfy our test project requirements. Finally, I placed the order in FS, and thanks to their fast shipping, I got the modules quickly.
