50m (164ft) Generic Compatible 40G QSFP+ Active Optical Cable

We bought 3 of these to link up some EX4600s in one room to some EX4300s in another room. These worked well as a typical 40Gb optical connection. But they are not compatible with Junipers virtual chassis. As soon as we enabled VCP on the port, the link would drop and stay down. Same thing with the 40Gb transceivers sold here. Ended up having to go with OEM for these, which worked flawlessly.

Support was great in trying to get it sorted out, but we ran out of time to keep testing.

The products I have needed and selected were always in stock. Customer service provided timely and comprehensive advice when needed.

Our data center is in construction. We have lots of devices in our data center, Juniper, Brocade, Cisco and Extreme, etc. I'm looking for alternative choices to branded ones and clicked around google, and find the website. FS ads are almost seen everywhere, which direct me to purchase here. I purchased many transceivers and AOC cables. I'm happy with transceivers part, all of therm are shipped almost immediately. But I was told the Cisco 2m AOC has not sufficient stock at that time. It's a little pity. I hope you guys can prepare more stock for AOC cables. Our data center needs large QTY in 2018. I'm also happy to receive all goods within a week. Keep doing well!
