Specifications

Cisco QDD-400G-DR4-S Compatible 400GBASE-DR4 QSFP-DD PAM4 Optical Transceiver Module (SMF, 1310nm, 500m, MTP/MPO, DOM)

 

400GBASE-DR4 QSFP-DD transceiver is designed for 400G Ethernet interconnection, allowing link up length up to 500m over single-mode fiber (SMF) with MTP/MPO connector. It is compliant with the QSFP-DD MSA, IEEE 802.3bs standard. The 400GBASE DR4 module converts 8 channels of 50Gb/s (PAM4) electrical signals into four parallel lanes of optical signals, each lane capable of 100Gb/s. It supports 4x100G breakout to QSFP28 100G-DR, 100G-FR, and 100G-LR transceivers. Utilizing PAM4 modulation technology, 400GBASE-DR4 provides a cost-effective and low power consumption solution for 400G Ethernet applications, data centers, Infiniband interconnects, and high-performance computing networks.

  • Does 400GBASE-SR8 support DSP?
    Yes, The 400GBASE-SR8 incorporates DSP (Digital Signal Processing) technology, offering greater flexibility than CDR. DSP allows for tailored configuration adjustments to accommodate diverse application requirements.
  • I want to build a 850m optical link, can I use The 400GBASE-FR4?
    Yes, The 400GBASE-FR4 optical module's maximum transmission distance is 2 km, so it can be used for an 850m connection.
  • What type of optical cable should be used with 400G-SR8?
    The 400G-SR8 optical module employs a single-row, angled (APC) MTP16 connector to establish a connection with parallel multi-mode fiber, facilitating the linkage of 8 fiber pairs. We recommend utilizing the QSFPTEK MTP-16 APC OM4 Cable for optimal performance.

    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!

    I finally received it after 2 weeks, it's very easy to use, faster and more energy efficient than buying other transceivers before.
