Review on 1m 40G QSFP+ to 4xSFP+ Breakout DAC - 40GBASE-CR4 Passive Direct Attach Copper Twinax QSFP to SFP Cable for HPE JG329A Devices by Emmanuel Chouinard
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.
- At 10Gtek Signal Integrity Lab we are 100% TDR and VNA tested. And each DAC cable is individually tested on the switches before shipping
- There are defects
