      The qsfp28-100g-lr4 modules have performed excellently in my Arista 7050X3 with no problems encountered. They have delivered the expected speeds and have been working flawlessly for three months. Installation was a breeze and essentially a plug-and-play process.

      The QSFPTEK qsfp28 fiber transceivers worked right away. Easy to install, pretty much plug and play. I see no retransmits or other faults.
