Yes we received everything and cables/transceivers worked perfectly fine in our lab, so nothing to complain about.
I haven't tested the FS box yet, but I will use the user guide you sent me.
Thank you very much!

Hohe Geschwindigkeit, lange Übertragungsstrecke und geringer Einfügungsverlust

My personal account manager at FS.COM was very helpful when I tried to figure out compatibility between their modules and devices already in my system. Their prices were excellent, the equipment arrived on time, and my upgraded system is working perfectly. I will buy them again. Really a nice buying experience.

Comes in a small and secure box padded with rubber like foam for protection. Worked immediately once I’ve installed them on my Cisco Nexus 9332PQ switch. Very satisfied!

Habe 4 Stück als Ersatz bestellt. Alle funktionieren einwandfrei wie erwartet.

I got 2 of these to test, once connected to my Juniper QFX3500 it met or excelled every burst and sustained test that we gave it. I don't see any difference between them and Juniper's own transceivers. So you can get the same functionality at a much lower cost by using these third-party transceivers.
