Review on QSFPTEK 10G SFP+ DAC Cable by Jason Ingram

Revainrating 5 out of 5

Excellent Cable: Computers and Accessories

Works with Juniper switches (EX-2300x, EX4300). It ticks all the boxes: - affordable - flexible - works. I haven't tested Arista yet and I'm really not sure how it will work since Arista has decided 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.

Pros
  • DAC Function: 10Gbps SFP+ to SFP+ Direct Attach Copper Twinax Cable Passive 1 Meter AWG30. Widely compatible with Cisco, Ubiquiti, D-Link, Netgear, Mikrotik, other Open Switch devices, etc.
Cons
  • Doubtful
