  • 400G PAM4 QSFP-DD to 2x200G QSFP56 DAC Cable 3MProduct Overview:

    The 400G PAM4 QSFP-DD to 2x200G QSFP56 DAC Cable is a high-performance, cost-effective solution designed to cater to the demanding bandwidth requirements of modern data centers and high-speed networking environments. This cable effectively splits a single 400Gbps QSFP-DD output into two 200Gbps QSFP56 connections.

    Key Features:

    1. Advanced PAM4 Modulation: Uses Pulse Amplitude Modulation (PAM4) technology, enabling higher data transfer rates by transmitting multiple bits of data with each signal change, thus enhancing the overall data throughput.
    2. High-Density Connectivity: Splits one 400Gbps QSFP-DD interface into two separate 200Gbps QSFP56 channels, optimizing port utilization and supporting scalable network architectures.
    3. Direct Attach Copper Construction: Employs robust copper cabling for direct attachment, ensuring low-latency, reliable, and secure data transmission without the need for active electronic components.
    4. Energy Efficiency: Offers an energy-saving alternative to optical cables, significantly reducing power consumption and operational costs in data centers.
    5. Ease of Deployment: Designed for plug-and-play installation, this cable simplifies setup processes, requiring no additional configuration for immediate operational deployment.
    6. Broad Compatibility: Conforms to industry standards for QSFP-DD and QSFP56 interfaces, ensuring compatibility with a wide array of network equipment and facilitating seamless integration.


    • Perfect for high-performance computing, cloud storage solutions, and large-scale networking in data centers demanding efficient, high-speed data transfer capabilities.
    • Suitable for streamlining network infrastructures by aggregating multiple 200Gbps connections into a single 400Gbps channel.
    • Commonly used in network backbones, metro network environments, and in connecting servers and storage units in hyper-scale data centers.


    • Cable Type: Passive Direct Attach Copper (DAC)
    • Data Rate: 400 Gbps (QSFP-DD) split into two 200 Gbps (QSFP56) channels
    • Connector Type: QSFP-DD to 2x QSFP56
    • Maximum Cable Length: Available in various lengths to accommodate specific networking requirements

    The 400G PAM4 QSFP-DD to 2x200G QSFP56 DAC Cable is an essential component for next-generation data centers, offering a blend of high-speed data transmission, energy efficiency, and adaptability, making it an ideal choice for future-proofing network infrastructures.
