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.
Product Deployment
1. Leaf-to-Spine Switch Connections
- Product: 800G OSFP DAC /ACC Cables
- Application: Intra-rack or adjacent-rack switch connections
- Distance Support: Up to 5 meters
- Benefits: Ultra-low latency, low power consumption, simplified deployment
2. Server-to-Leaf Switch Connections
- Products:
- 800G OSFP 2xDR4 (2× 400G DR4 interfaces)
- 400G OSFP DR4
- Distance Support: Up to 100 meters (single-mode fiber)
- Benefits: High-speed, long-reach communication with low bit error rates (BER)
Why This Hybrid Approach?
- Cost Efficiency: Use of DAC/ACC cables within racks eliminates unnecessary transceivers.
- Performance Optimization: Single-mode transceivers ensure stable performance across longer links without sacrificing bandwidth.
- Scalability: Supports future expansion with minimal infrastructure change.
- Flexibility: Adaptable to various data center topologies, whether centralized or distributed.
This combination of technologies provides the optimal solution for hyperscale and AI-driven data centers that demand uncompromising speed, stability, and scalability in every connection.
