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.

I plugged it into the switch and it was picked up soon by my device. I also used it to break the 800G into 2x 400G links. That works well too. The transfer efficiency meets my expectation. Anyway, so far no problem occurs. I‘m quite satisfied with this buying.

Using this 800G DR8 module bought here can be very nice. The basic performances are absolutely fine. We have used them for almost a month. They are much assured of the quality.

I found some information about 800G on Google, then found the FS. Though I had bought products at FS for many times, I didn't know they begin to supply 800G products. Emm, I decided to give a try for this module for our switches and placed the order.

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.

Bought one pair for testing on switches. They matched well and everything went great. Would consider buying more here over time.
