Review on 🔌 40G QSFP+ DAC Cable - High-Speed 40GBASE-CR4 Copper Twinax QSFP Cable with 3M Axial Technology for Cisco, Meraki, Mikrotik by Khiam Burton

I bought a pair of these cables for use in my home lab. My company sent me a pair of EX3400 switches. Instead of spending tons of money on optics and cables, I decided to give them a try after being recommended on Reddit. I'm a CCNP R/S but my specialty is VoIP. So I'm not always up to date with factory connections from data centers. They worked like a charm and I was able to build a virtual chassis with little effort. I was able to share port channels between chassis. Everything works exactly how I want it. There are no switching errors. I am currently using Junos 20.4R1.12. Since this is a lab, I can't tell how they would perform in a real data center application. But I would imagine they would work just fine.
