      Deployed two dozen of these compatible QSFP28 modules into our Cisco Nexus 9236C and 9336C-FX2 switches for a 100G spine-leaf upgrade. Compatibility has been perfect – they were recognized immediately without any issues. The packaging was professional and secure, with each module in its own anti-static bubble wrap bag, and they arrived surprisingly fast. We've been running them under constant load for three months now, and the performance is rock solid.

      This is a great deal for high-speed 500-meter connections. It worked perfectly with MPO-12 cabling, and integration was a breeze. The only drawback is that it needs parallel fiber infrastructure, which adds to cabling costs if it's not already in place. It's a solid choice for short-range data center links, and it won't break the bank.

      Man, their product page for this QSFP-100G-PSM4-S module was super clear and detailed. After checking out the connectivity solution, I went ahead and bought that PSM4 module. I also grabbed MPO breakout cables and 25G SR modules to go with it. One thing I noticed though – their page only really pushed the MTP cables. But sale rep. Yanny recommended me the MPO cable. Way better discount! Think it might be a new thing they just got? Anyway..., the whole buying thing was smooth as butter. And their customer service? Totally on point!

      Purchased 100GBASE-PSM4 along with some 25G modules, and was pleased that QSFPTEK offered us a large order discount to save a lot of money on this order. Meanwhile, QSFPTEK's customer service staff answered all our requests with patience and professionalism.

      Upgrading our network equipment to 100Gbps, so we also need 100G optical modules, we looked many brands online, and QSFPTEK most impressed me is the quality of their customer service, for any of my questions always respond to a timely and professional answer, so I am very impressed!
