    Frequently Asked Questions (FAQ)

    Q: What is the difference between QSFP+ to QSFP+ and QSFP+ to 4 SFP+ cables?

    A QSFP+ to QSFP+ cable is used to connect two 40G ports directly. A QSFP+ to 4 SFP+ breakout cable connects a 40G port on one end to four 10G SFP+ ports on the other end, allowing the split of 40G bandwidth into four 10G channels.

    Q: Why do longer passive copper cables use a thicker wire gauge (like 24AWG or 26AWG)?

    Longer cables suffer from higher signal attenuation. Thicker copper conductors (represented by lower AWG numbers such as 24AWG or 26AWG) have lower electrical resistance, which helps maintain signal integrity over longer distances up to 7 meters.

    Q: Do these passive copper cables require external power to operate?

    No, passive Direct Attach Copper (DAC) cables do not contain active components or optical transceivers. They draw zero power from the host equipment, making them an extremely cost-effective and energy-efficient solution.

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

    The operating temperature range for these cables is 0 to 70°C (32 to 158°F). This is standard commercial grade, suitable for deployment in temperature-controlled data centers and server rooms.

    Q: Are these 40G QSFP+ cables hot-pluggable?

    Yes, they are fully hot-pluggable. You can insert or remove the cables without powering down the host switches or network devices, ensuring zero disruption to the rest of the network.
