    Cisco Compatible DR8 QSFP-DD 800G PAM4 Optical Transceiver Module (1310nm, 500m, MPO-16/APC, SMF, 0℃ to +70℃, DDM)

     

    Cisco Compatible DR8 QSFP-DD 800G transceiver module supports a max data rate of 850Gbps. It enables the fiber link of 500m over single-mode fiber (SMF) with MPO-16 connectors. The 800 Gigabit Ethernet signal is carried over 1310nm wavelengths. QSFPTEK manufactured  800G QSFPDD-DR8 complies with IEEE 802.3cu-2021, IEEE P802.3ck D3.0, QSFP-DD MSA HW Rev 6.01, CMIS Rev 5.0. DDM (digital diagnostics monitoring) function is supported on the 800G fiber optic transceiver to achieve real-time operating parameters monitoring. Adopting the Pulse-amplitude Modulation (PAM4) modulation, the DR8 QSFP-DD achieves 800 Gigabit Ethernet through 8x 106.25 PAM4 Retimed 2x400GAUI-4 C2M electrical interface. The 800G DR8 QSFP-DD is widely used for 800 gigabit Ethernet, data centers, 800G to 2x 400G DR4, or 8x 100G DR applications.

      We selected this module after comparing several options for our network upgrade. The specifications matched our design requirements, and it gave our engineering team more confidence during the planning stage. A good choice for high-bandwidth applications.

      Plugged these 800G DR8s into our Cisco switches for a breakout setup. No compatibility issues and temperatures are normal under heavy load. Solid performance so far.

      This was purchased for a proof-of-concept environment before a larger rollout. After several days of validation, the results were positive enough that we've decided to use the same model in the next phase of the project.

      After the network was put into production, we barely had to think about these modules again—which is probably the best compliment for networking hardware. They simply did their job without generating unnecessary maintenance work.

      We've sourced optics from several vendors over the years, and this is one of the few products that required almost no follow-up after delivery. The documentation was complete, the module matched the specifications, and the entire deployment went according to plan.

      The overall quality exceeded my expectations. The module feels durable, the finish is clean, and everything from the connector to the housing appears to be well manufactured. It gave us confidence before we even powered it on.

      I was working against a tight deployment schedule, so delivery time was important. The order was processed quickly, and the shipment arrived a little earlier than expected. That helped us complete the installation without delaying the project.
