Frequently Asked Questions
What is a 100G passive DAC cable and why should I use one?
A 100G passive direct attach cable is a copper interconnect that delivers 100 Gigabit Ethernet speeds over short distances (typically up to 5 meters) without requiring power. Unlike active cables, passive DACs are more cost-effective, generate less heat, and have lower latency—making them ideal for data center rack-to-rack connections, switch-to-server links, and storage area networks.
Is this MELLANOX DAC cable compatible with my equipment?
Yes, the ADD-ON MELLANOX COMP DAC is designed for full compatibility with MELLANOX switches, NICs, and systems featuring QSFP28 ports. It also works with any standard QSFP28-equipped networking hardware from other vendors. Always verify your equipment supports 100GbE QSFP28 connectivity before purchase.
How long can I run this 1-meter 100GB copper cable without signal degradation?
The 1-meter length is optimized for short-reach applications with zero signal degradation. Passive copper DACs maintain full 100 Gigabit performance up to approximately 5 meters depending on cable quality and environmental factors. For distances beyond 5 meters, active DAC cables or fiber optics are recommended.
What makes passive DAC cables better than active alternatives?
Passive 100G DAC cables offer lower cost, zero power consumption, minimal latency, and exceptional reliability compared to active solutions. They're ideal for permanent installations in controlled data center environments. Active cables are better suited for longer distances or high-EMI environments where signal conditioning is necessary.
