400G QSFP-DD DAC Cable - High-Speed Data Transmission Solution from China Suppliers and Factory

,

The ETU-LINK 400G QSFP-DD DAC cable is a high-performance direct attach copper solution designed for seamless connectivity between two 400G QSFP-DD ports. As a leading product from a trusted China factory, this cable offers a cost-effective, energy-efficient, and low-latency option for short-distance data transmission within data centers. Its innovative breakout mode allows users to split a single 400G QSFP-DD port into four 100G QSFP ports, ensuring enhanced flexibility in data transmission. This makes it an ideal choice for data center suppliers looking to fulfill high-speed and large-capacity data transmission requirements. By simplifying the cabling structure, the ETU-LINK cable significantly improves the reliability and stability of your data center operations.

    Frequently Asked Questions

    Q: What data rate do these QSFP-DD to QSFP-DD cables support?

    These cables support a high-speed data rate of up to 400G, making them ideal for high-density, high-bandwidth data center applications.

    Q: What is the difference between the 26AWG and 30AWG cable diameters?

    AWG refers to the wire thickness. The 30AWG cable (EDQD400-1) is thinner and more flexible, optimal for 1-meter lengths. The 26AWG cables (EDQD400-2-26 and EDQD400-2.5-26) have thicker conductors to maintain signal integrity over longer distances, such as 2 meters and 2.5 meters.

    Q: Are these 400G QSFP-DD cables active or passive?

    These are passive copper Direct Attach Cables (DAC). They require no power consumption and offer low latency, making them highly cost-effective for short-reach connections.

    Q: What is the operating temperature range for these cables?

    The operating temperature range is 0°C to 70°C, which meets standard commercial and enterprise-level environmental requirements.

    Q: Can I download the data sheets for these products?

    Yes, detailed specifications and technical data sheets are available for download for each P/N (EDQD400-1, EDQD400-2-26, and EDQD400-2.5-26) directly from the ordering information table.
