Frequently Asked Questions
What is a passive DAC cable and how does it differ from active alternatives?
A passive DAC (Direct Attach Copper) cable is a high-speed interconnect that connects directly between two QSFP28 ports without active signal conditioning. Unlike active DAC cables, passive models consume zero power and generate no heat, making them ideal for dense deployments. This 100G passive DAC cable provides cost-effective connectivity for shorter distances (up to 50cm) with exceptional reliability and minimal latency.
Is this 100G copper cable compatible with MELLANOX switches and infrastructure?
Yes, the ADD-ON MELLANOX COMP DAC is specifically designed for MELLANOX compatibility. The QSFP28 connectors and 100G passive specifications ensure seamless integration with MELLANOX switches, NICs, and other MELLANOX networking equipment. Always verify your specific hardware model supports passive DAC connectivity before deployment.
What are the advantages of choosing a 50cm passive DAC over longer cable runs?
The 50cm length is optimized for short-reach data center connections between adjacent equipment. Passive DAC cables perform best at shorter distances due to signal attenuation characteristics. This 100G passive DAC eliminates the need for active components, reducing costs, power consumption, and heat generation while maintaining full 100 Gbps performance for rack-to-rack and intra-cabinet connectivity.
Can I use this passive copper cable in high-temperature data center environments?
The MELLANOX COMP DAC operates reliably in environments up to 70°C. Its passive design generates zero operational heat, making it an excellent choice for thermally constrained data centers. The robust copper construction ensures stable performance across the full operating temperature range without signal degradation.
