The Cisco QDD-400G-LR8 compatible optical transceiver module is designed with duplex LC connectors, reaching a link up to 10km over a standard pair of G.652 single-mode fiber(OS2). QSFPTEK manufactured 400GBASE-LR8 QSFP-DD transceiver module is compliant with QSFP-DD MSA, IEEE 802.3bs protocol, and 400GAUI-8/CEI-56G-VSR-PAM4 standard. Besides, 400G LR8 is designed based on PAM4 (Pulse Amplitude Modulation 4-level) modulation technology, DSP (Digital Signal Processing) chip, and QSFP-DD form factor. With these features, this 400G QSFP-DD transceiver is widely applied in 400G telecom connections, DCI, metro network, long-haul, and high-performance computing networks application.

QT-QSFP-DD-LR8.pdf
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.

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!
