Review on 40 Gigabit QSFP+ MPO Multi-Mode Transceiver by Ray Mcknight

I had a problem with some other generic transceivers like this one. They work fine on the traditional connection, but as soon as I enable the Juniper Virtual Chassis port, the connection drops and remains unavailable. There seems to be some kind of compatibility issue as there weren't any issues with the OEM transceivers. If you're just using this as a 40Gb direct connection, it's great. However, if you have a virtual chassis configuration, you will need to look for OEM hardware, either new or auctioned. I got mine at a great price.
