      Bought this to upgrade our Juniper QFX10002 switch. Big shoutout to the sales rep Talia for double-checking the compatibility before shipping.

      This 100G SR4 module is a perfect fit for my Juniper switch, no additional configuration required, plug and play, at the same time, this module only took three days to deliver, just can't imagine, agree with QSFPTEK's work efficiency.

      For my needs, it's a great price and a highly usable module. Since I don't frequently use 100Gb, I plan to run a breakout cable on this module to connect to some Mellanox 25Gb cards.

      In a meeting, my partner introduced QSFPTEK and spoke highly of their products and professional services. Then I wanted to try it out. I have to say that both the engineer and the account manager are very professional. They answered my application questions and recommended suitable MTP cables and modules.

      No compatibility issues so far, and I use it on a fairly wide range of devices. Their output power is relatively stable, and there is no packet loss problem or CRC error like the products I bought before. It works as expected in my Juniper QFX5120 (plug them in and both ports work fine). There are no issues to report. Thanks!

      So far, this QSFP28 module has performed as hoped. The seller seems very keen to provide quality customer service, so I am sure I will buy from again should the need arise.
