  • 400G PAM4 QSFP-DD to 4x100G QSFP56 PAM4 DAC Cable

    Product Overview:

    The 400G PAM4 QSFP-DD to 4x100G QSFP56 PAM4 DAC Cable is a premium networking solution designed for ultra-high-speed data transmission in modern data centers and networking environments. This cable utilizes the PAM4 modulation technique to effectively distribute a 400Gbps QSFP-DD signal into four separate 100Gbps QSFP56 channels.

    Key Features:

    1. Advanced PAM4 Signaling: Employs Pulse Amplitude Modulation (PAM4) technology, which doubles the data rate transmission by sending two bits of data in each signal change, enhancing overall bandwidth efficiency.
    2. High-Density Configuration: Facilitates the conversion of a single 400Gbps QSFP-DD interface to four individual 100Gbps QSFP56 ports, optimizing port usage and infrastructure scalability.
    3. Direct Attach Copper Design: Utilizes robust and reliable copper cabling, ensuring stable and secure data transfer without the need for active electronic components.
    4. Energy-Efficient Solution: Offers a more power-saving alternative compared to optical solutions, reducing operational costs in data centers.
    5. Plug-and-Play Operation: Designed for straightforward deployment without complex configuration, offering ease of use and minimal installation time.
    6. Compatibility and Interoperability: Adheres to industry standards, ensuring compatibility with a wide range of networking equipment that supports QSFP-DD and QSFP56 interfaces.


    • Ideal for high-performance computing centers, cloud storage, and large-scale data centers requiring high-speed data transfer.
    • Suitable for aggregating multiple 100Gbps links into a single 400Gbps connection, streamlining network infrastructure.
    • Used in network backbones, metro networks, and as part of the interconnects in hyper-scale data centers.


    • Cable Type: Passive Direct Attach Copper (DAC)
    • Data Rate: 400 Gbps (QSFP-DD) split into four 100 Gbps (QSFP56) channels
    • Connector Type: QSFP-DD to 4x QSFP56
    • Maximum Cable Length: Available in various lengths to accommodate different networking needs

    The 400G PAM4 QSFP-DD to 4x100G QSFP56 PAM4 DAC Cable is a future-proof solution, bringing together the latest in high-speed data transmission technology and energy efficiency, making it an excellent choice for forward-looking data center expansion and upgrade strategies.
