I am extremely impressed with the performance of the 40G QSFP+ to 10G SFP+ adapter converter module. Amidst rigorous daily use, it has maintained high-speed connectivity and has not shown any signs of slowdowns or issues. The ease of installation and the cost savings over the OEM version have made it a standout product for our network team. It's refreshing to find an affordable solution that doesn't compromise on quality or performance.

The Cisco QSFP-SFP10G-CVR compatible converter module from FS.com made our network expansion a breeze. Its ability to convert a single 40G port into four 10G ports provided us with the flexibility to connect more devices without any network overhauls. The data throughput has been consistent, with no packet loss or issues, which is critical for our data-sensitive operations. This module proves that you can achieve excellent network efficiency without compromise.

Work as advertised !!! Shipping is quick and support communication is excellent.

Customized 40G QSFP+ to 10G SFP+ Adapter Converter Module works perfectly to us. Thank so much FS team...Credit to Muriel Pan.

Yes we received everything and cables/transceivers worked perfectly fine in our lab, so nothing to complain about.
I haven't tested the FS box yet, but I will use the user guide you sent me.
Thank you very much!

I finally got to test the QSFP to SFP+ modules in our Cisco Nexus 9336s and Nexus 9364s and they work just fine. That is good news.
We're now trying to figure out what quantity of these that we need to order.I expect to be asking you for a quote in a few days and then we'll place the order via Purchase Order shortly thereafter.

With nexus n6001 and no link.

Everything was as hoped for. Our Account Manager (Bunny) was knowledgeable and saved us both order mistakes and time.

Excellent product and superfast delivery !
