This product did not worked for what I had originally bought it for however, It was high quality and seemed like it would take a beating if needed.

Just as advertised, they plugin, they work, and data flows. Great price too. We purchased 7 of these for connectivity to the fiber backplane for virtualization and all is great.

Solid Cables. Work fine in my home lab.

it is not working

I bought this becauseA) It's faster for me expense small amounts than go through the PO processB) This is what Amazon hadIt's installed at a remote location so I haven't laid eyes on it, but it seems to be working fine

Great product and fast shipping!

These say Cisco compatible, but they did not work with our specific model of Cisco switch. They were seen as an unknown SFP type. We bought twinax cables from Tripplite as well (on Amazon.com), and they work fine. These are what worked for us: http://amzn.com/B00BPQBB4W.
