Review on 🔌 QSFPTEK 10G SFP+ DAC Cable, 5m (16 Foot) for Cisco SFP-H10GB-CU5M & Ubiquiti Netgear Open Switch Devices: High-speed Passive Direct Attach SFP+ to SFP+ Copper Twinax Cable by Daniel Pesicek

Works with Juniper switches (EX-2300x, EX4300). Meets all the important points: - affordable - flexible - works. I haven't tested it on Arista yet and I'm really not sure how it will be because Arista chose to block non-Arista optics. 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.
