    I'm a regular shopper here, and once again, I'm thoroughly pleased with my experience. The MTP-12 connector it features makes upgrading from 100G to 400G a breeze. I can seamlessly continue using my existing MTP-12 fiber without any hassle. Great job!

    To trial a 400G connection between our Cisco Nexus 3000 switches, we required multiple 400G optical transceivers. Before placing the order, I consulted my account manager regarding compatibility concerns. Fortunately, the QDD-400G-DR4-S transceivers we purchased were fully compatible with our switches, and we have not encountered any issues thus far.
