Frequently Asked Questions
What is a 100G passive DAC cable used for?
A 100G passive DAC cable provides direct-attach connectivity between switches, servers, and storage systems in data center environments. It delivers 100 Gigabit Ethernet speeds without the cost and complexity of active solutions or optical transceivers, making it ideal for high-speed interconnects within equipment racks.
Is this MELLANOX DAC cable compatible with my existing infrastructure?
Yes, this ADD-ON MELLANOX-compatible cable features standard QSFP28 connectors and passive technology, ensuring compatibility with MELLANOX switches, network interface cards, and other QSFP28-equipped systems. Verify your equipment supports 100G passive DAC connectivity before deployment.
How does a 3-meter passive copper DAC compare to active solutions?
Passive DAC cables eliminate active electronics, reducing cost, power consumption, and heat generation while maintaining excellent signal integrity up to 3 meters. For distances beyond 3 meters or higher port density requirements, active DAC or optical solutions may be necessary.
What are the advantages of choosing passive DAC technology?
Passive DAC technology offers lower total cost of ownership, zero power requirements, minimal latency, and simplified deployment compared to active alternatives. This makes it the preferred choice for cost-conscious enterprises building high-speed 100G data center networks.
