Same or better quality than Cisco, much better prices and fast shipping from Amazon

I have ordered many different variants of 10Gtek cables from Amazon. I've used them extensively on Nexus 3000/9000 platforms and they work great. I also have them on my Cisco Catalyst switches, specifically the 10 Gigabit ports on the 4948 switches. If I can order them off Amazon and get them in a day or two, it's a no-brainer. I've tried a few other non-Cisco brands and have encountered intermittent cable issues. Now that they've worked so well for us, that's all we order.

Pros

At 10Gtek Signal Integrity Lab we are 100% TDR and VNA tested. And each DAC cable is individually tested on the switches before shipping

Cons

There are defects
