Transceivers type QDD-400G-SR8-S | 100m
After reaching out to multiple vendors regarding the 400G QSFP-DD optical modules, I found that their delivery timelines didn't align with the urgency of our test project. Eventually, I opted for QSFPTEK and was pleasantly surprised by their swift shipping, allowing us to acquire the modules promptly to meet our project needs.

This is my second time buying from QSFPTEK, and I gotta say, they've been solid. Last year, I grabbed some 100G QSFP28 SR4 and 10G modules for a project, and they've been chugging along without a hitch. So, when my company needed some 400G modules for our spine-leaf connections, QSFPTEK was the first place I thought of. And man, was I relieved to see they had them in stock. Talia threw in a recommendation for an MTP-16 OM4 cable to hook up the transceiver to my switch, so I figured why not? Three days later, the goods were at my door. Couldn't be happier with the whole deal.

A few years ago, we collaborated with QSFPTEK to deploy our 10G network, primarily because their products were cost-effective. I never thought that I could depend on QSFPTEK for our high-speed transmission needs as well. To my surprise, QSFPTEK continued to make progress, and their 400G modules and MTP cables worked seamlessly with our Cisco switches, resulting in a smooth 400G direct connection.

Our goal was to upgrade our network system to achieve higher speeds, so we opted for a 400G upgrade and needed to select appropriate transceivers. Since we didn't require long-distance transmission, the 400GBASE-SR8 transceivers were the perfect fit for us. Initially, we were apprehensive that these modules might not be compatible with our Cisco switches, but to our delight, they exhibited outstanding connectivity, and all performance metrics were within normal parameters. I highly recommend them!
