Can I use this from Dell S5232 to connect a Dell server with 10G NIC?

Works great. I used to connect Supermicro servers to a Dell switch.

Great quality and excellent cable build. We\'ve bought this multiple times

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

Perfect Quality. Works as expected. I used this cable to link a mellanox Connect-x 3 card with a QSFP ending (40gpbs) in my workstation to a standard SFP+ switch at 10gbps. Only the first link works (you have to leave 3 sfp+ endings hanging) but saves you from buying a QSA (QSFP to SFP+ adapter) and a SFP+ DAC cable instead.

Good quality

Use the cable to connect from Arista DCS-7060CX-32S to Brocade ICX 7250.

the cables and it just works.

Very pleased with the quality of the 40G QSFP+ to 4 SFP+ DAC. I ordered many different lengths of DAC cables and used them extensively on Nexus 6000 and 9000 series and they all performed perfectly. Highly recommend these items which feature with great compatibility and excellent performing.

I’ve tried the breakout cables in Cisco Nexus 5000 N55-M4Q and they worked very well. These days, we are planning to purchase new equipment for our project and we will still choose FS as the first site.

Still remembered the first deal with FS. We had the equipment with 100G CFP port, and wanted to buy QSFP28 modules to connect our 100G CFP module. But we didn’t know whether it was OK. So we asked FS whether they could do the test. The technical staff kindly tested the connection of 100G CFP and QSFP28 of the same wavelength. And they sent the testing report to us. We bought the 100G QSFP28 modules, and they worked fine with our CFP module.
This time, we came again and decided to use 40G and 10G modules to make 40-10G connection. The sales knew our network environment, we planned to make the connection in the streaming room, and the devices were about 2m away from each other. So the guy recommended the DAC cable #30903. A much more cost-effective product for us.
