    Frequently Asked Questions

    Q What is the difference between QSFP28 to QSFP28 and QSFP28 to 4 SFP28 cables?
    QSFP28 to QSFP28 cables connect two 100G ports directly for high-throughput backbone links. QSFP28 to 4 SFP28 breakout cables split a single 100G port into four individual 25G SFP28 channels, which is ideal for connecting high-speed switches to servers.
    Q Why do longer cables use 26AWG while shorter ones use 30AWG?
    AWG (American Wire Gauge) measures wire thickness. Thicker wires (26AWG) have lower signal attenuation, making them necessary for reliable 100G transmission over longer distances like 5 meters. Shorter cables (1M to 3M) can use thinner 30AWG wires, which offer better flexibility and airflow management.
    Q Are these 100G QSFP28 passive copper cables hot-pluggable?
    Yes, these cables are designed to be fully hot-pluggable. You can insert or remove them from MSA-compliant ports without powering down the host system, ensuring zero disruption to your active network services.
    Q Do passive DAC cables require external power to operate?
    No, passive Direct Attach Copper (DAC) cables do not contain active electronics or optical components. They draw zero electrical power from the switches and introduce virtually no latency, making them highly energy-efficient and cost-effective.
    Q 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), which is suitable for most enterprise data centers and network closets.
