China 400G QSFP-DD DAC Cable - Reliable, Flexible Solution from Leading Suppliers and Factory

,

The ETU-LINK 400G QSFP-DD DAC is a high-performance direct attach copper cable specifically designed to connect two 400G QSFP-DD ports. As a leading choice among China suppliers, this cable offers a cost-effective, energy-efficient, and low-latency solution ideal for short-distance data transmission within data centers. Furthermore, it features a breakout mode that allows a single 400G QSFP-DD port to be split into four 100G QSFP ports, providing enhanced flexibility in data transmission. Manufactured in our state-of-the-art factory, this cable is widely utilized in data centers to address high-speed and large-capacity data transmission requirements, simplifying the cabling structure and significantly improving the reliability and stability of your data center.

    Frequently Asked Questions

    What is the difference between 30AWG and 26AWG in these cables?

    AWG (American Wire Gauge) measures the wire thickness. Thicker wire (26AWG) has lower attenuation and supports longer distances (up to 2.5 meters), whereas thinner wire (30AWG) is more flexible and suitable for shorter distances (1 meter).

    Are these QSFP-DD 400G passive cables hot-pluggable?

    Yes, these cables are fully hot-pluggable, allowing you to insert and remove them from the ports without shutting down the host systems or interrupting active network traffic.

    Do these cables require external power to operate?

    No, these are passive direct attach copper (DAC) cables. They do not contain active electronics or optical components, meaning they draw zero power from the host switch or router interface.

    What standards and specifications do these cables comply with?

    These 400G QSFP-DD cables comply with the QSFP-DD Multi-Source Agreement (MSA), IEEE 802.3cd, and standard industry requirements to ensure seamless interoperability.

    What is the operating temperature range for these cables?

    These cables are rated for standard commercial operating temperatures ranging from 0°C to 70°C (32°F to 158°F), suitable for standard data center environments.
