Excellent Cable in Computers & Accessories

Works with Juniper switches (EX-2300x, EX4300). It ticks all the boxes: accessibility, flexibility, performance. I haven't tested Arista yet and I'm really not sure how it will work thanks to Arista's solution. for blocking optics is not Arista. I've seen DACs handled differently than optics in some hardware in the past, but I'm not sure if Arista does the same or if the dumb blocking extends to DACs as well. I'll update after I pull Arista out of memory and test it. Update: Work between Juniper EX4300 and Arista 7050S-64. Can't comment on other Arista models but seems to work with 7050S-64.

Pros

DAC Feature: Twinax 10 Gbit/s SFP+ to SFP+ Direct Attach copper cable, passive, 0.5 m, AWG30. Widely compatible with Cisco, Ubiquiti, D-Link, Netgear, Mikrotik, other open switch devices, etc. Notes. An SFP+ cable works the same as an SFP+ module, which cannot be used in an encryption key switch. This DAC cable cannot be used in HP or Intel, and others require a special encryption code switch.

Cons
