Optimized Connectivity with Single-Mode Transceivers and 800G DAC/ACC Cables

Optimized Connectivity with Single-Mode Transceivers and 800G DAC/ACC Cables

In high-performance data center environments, balancing short-reach and long-reach connections is essential to achieving low-latency communication and optimal infrastructure efficiency. Combining 800G DAC/ACC cables and single-mode transceivers presents an ideal hybrid solution to meet these demands.

Use Case: Hybrid Leaf-Spine and Server Connectivity

To ensure both scalability and ultra-fast data transfer, data centers often colocate Leaf and Spine switches in the same or adjacent racks. For these short-distance connections, 800G DAC (Direct Attach Cable) and ACC (Active Copper Cable) offer a cost-effective and low-latency solution.

Simultaneously, server-to-Leaf switch connections can vary in length, and high-speed single-mode optical transceivers ensure reliable long-reach communication, maintaining stable network performance across extended distances.
