Frequently Asked Questions
What is an 800GBase-CU direct attach cable used for?
An 800GBase-CU direct attach cable connects OSFP ports on switches, servers, and storage systems in data centers. It enables 800G InfiniBand connectivity over short distances (typically up to 2-3 meters) without the cost and complexity of optical transceivers, making it ideal for HPC clusters, AI training environments, and enterprise storage networks.
Why choose passive twinax over active optical cables?
Passive twinax cables like the AddOn MCP4Y10-N002 offer significant advantages: zero power consumption, zero latency, lower total cost of ownership, and proven reliability in production environments. For short-reach applications under 3 meters, passive copper twinax delivers identical performance to active optical solutions without the transceiver expense.
Is the AddOn MCP4Y10-N002 compatible with Mellanox switches?
Yes. The AddOn MCP4Y10-N002 is fully compatible with Mellanox/NVIDIA InfiniBand switches and servers equipped with OSFP ports. It is certified for enterprise environments and supports 800G fabric deployments in Mellanox-based data center architectures.
What does TAA compliance mean for this cable?
TAA (Trade Agreements Act) compliance certifies that the AddOn MCP4Y10-N002 meets U.S. government procurement standards. This designation is required for federal agencies, contractors, and organizations subject to Buy American provisions, ensuring eligibility for government and regulated sector purchases.
