    In terms of the same performance, I prefer to choose QT. The price is very competitive, making it a great value. As soon as the package arrived, I plug it into my Juniper switch and to be recognized in three seconds, amazing, and I like the vivid blue pull ring, which make it easy to plug and unplug operation.

    Great product at an excellent price. Works brilliantly on our Arista DCS-7150S. I've always had a good experience when dealing with QSFPTEK.

    These seem to work well. I have two 48 port switches stacked together using these and I have had no issues over the last six months since I installed it.

    Plugged in and it was automatically detected as a 40 Gigabit QSFP port. For the price, this is hard to beat. Connection is stable.

    These qsfp modules just work. I purchased 4pcs for QSFP ports on a Juniper switch QFX5100-24Q. Tested one month, they worked flawlessly without any issues. Full 40-gigabit throughput on all channels. Highly recommended!

    I bought these QSFPs for my company. Tested in Arista, Cisco, and Juniper they all recognized the QSFPs and started working right away with zero issues!

    They shipped from China and were an offline order only, so at first, I was a bit skeptical. Unexpectedly I got the package in a week and the item tests fine with my EX4300 switch.
