I need to connect a Mellanox SN2100 switch and ConnectX-5 adapter cards. I customized DAC cables here and directly used them. The whole network performs stably now and nothing goes wrong. By the way, the package and delivery both deserve to be mentioned. The package is so firm that all are in good conditions. And their fast shipping impressed me...

This cable was priced very competitively and worked exactly as intended. I ordered some with one end coded for Dell and the other for Mellanox. They are sturdy looking, easy to plug in & remove, and seat in the QSFP28 slot firmly. I have them now up and running to link my Dell Z9100-ON switches and Mellanox SN2700 switches. Each device showed a link within moments of plugging the cables in and I haven't had any disconnects. I like these cables because they are more durable than fiber cables and I have switched over to these DAC cables on my 100G switches and all have worked flawlessly.

Have used other FS DAC cables in the past as switch uplinks, always work perfectly. Now I got a ton of FS cables in my data center and will continue to use it in production with no doubts.

I hava an Arista 7160 switch and OpenDrives Summit NAS with Mellanox cards in it. I don’t want to buy original transceivers to connect the two devices due to high price. My A.M. told me they can help to customize DAC cable to fit my Arista switch and Mellanox cards. I am very satisfied. Much cheaper and very easy to use.

Our switch is Huawei S5720-32X-EI-AC. Customer staff told me it cab be well compatible, so I buy this one. DAC is much cheaper than transceivers and easy to install. Meanwhile, I'm very satisfied with the delivery. Will support next time.

Prompt and accurate! What's not to like?

They seem like good peoples.
