I bought these to connect two new office buildings to our existing Juniper base switches. I have used them in two Netgear GS752TXP-100NES switches connected to two Juniper ex4300 switches and also connected directly to a Dell r730's fiber optic network adapter. I can confirm a 10 GB connection in all cases. This is exactly what I was looking for and they did exactly what I needed.
