    Frequently Asked Questions (FAQ)

    Q What is the difference between QSFP28 to QSFP28 and QSFP28 to 4 SFP28 cables?
    QSFP28 to QSFP28 cables connect two 100G ports directly. QSFP28 to 4 SFP28 breakout cables split a single 100G port into four individual 25G channels, enabling connection between 100G switches and 25G servers or network interface cards (NICs).
    Q Why do longer cables (like 5M) use 26AWG instead of 30AWG?
    AWG (American Wire Gauge) indicates wire thickness. Lower gauge numbers (26AWG) have thicker copper conductors, which reduce signal attenuation over longer distances. Shorter runs (1M to 3M) can use thinner, more flexible 30AWG wire while maintaining optimal signal integrity.
    Q Are these passive DAC cables compatible with my hardware?
    These passive cables comply with QSFP28 MSA (Multi-Source Agreement) standards. They can be customized with specific brand EEPROM codes to ensure seamless plug-and-play compatibility with major networking equipment manufacturers.
    Q Do passive 100G copper cables consume power?
    No, passive Direct Attach Copper (DAC) cables do not contain active electronics or optical components. They operate purely on copper media, resulting in zero power consumption and lower heat generation compared to active optical cables (AOC).
    Q What is the maximum operating temperature for these cables?
    These cables are designed to operate reliably within a standard commercial temperature range of 0°C to 70°C, making them suitable for typical enterprise data centers and server room environments.
