    Frequently Asked Questions

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

    A: QSFP+ to QSFP+ cables connect two 40G ports directly for a single 40G link. QSFP+ to 4 SFP+ breakout cables split one 40G port into four independent 10G SFP+ ports, allowing connection between 40G switches and 10G host adapters or devices.

    Q:Why do different cable lengths have different AWG specifications?

    A: AWG (American Wire Gauge) measures wire thickness. Shorter cables (1M to 3M) typically use thinner 30AWG wire for better flexibility, while longer cables (5M to 7M) require thicker 26AWG or 24AWG wire to minimize signal loss over the extended distance.

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

    A: No, passive copper Direct Attach Cables (DAC) do not contain active electronic components for signal amplification, meaning they operate on zero power, making them highly energy-efficient and cost-effective.

    Q:Are these cables hot-pluggable in network devices?

    A: Yes, these cables support hot-plugging. You can insert or remove them from switches, routers, or network interface cards (NICs) without powering down the equipment, ensuring continuous network uptime.

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

    A: These cables are designed to operate efficiently within a standard commercial temperature range of 0°C to 70°C, making them suitable for most data center and enterprise server environments.
