1M Monoprice QSFP+ DAC $3.48 (ebay)

[adgenet]

I've been on a 40GbE buying spree lately so I've been searching ebay constantly and came across this:
www.ebay.com/itm/371880268245

I've had ok luck with monoprice for other things, no idea about DACs though.
That said, it's only $3.48.
I checked the monoprice website and it's listed at $12.80.
Unfortunately for me 1M is too short. Maybe a good deal for someone?

I usually use Cisco ones but at that price sure it's worth a chance.
Same also no issues with monoprice stuff but don't usually use high end

Got some random sitting around but for this price I'll snag 6 more to be SURE I have some that hopefully work ha ha!

Did these cables work for others?

Arista DCS-7050QX does NOT work.
Someone here noticed that these cables are incompatible with Trident-based switches.

As a confirmation: because these cables are so inexpensive, they were tested on my 7050 and did NOT work as previously reported.

Whether they work on other Trident-based systems is an open issue IMHO but we now have two confirmed tests where these cables did not work on the 7050.
