Next-Gen Data Center Interconnect
1.6T-Ready Architecture for AI Training Clusters & Extreme East-West Traffic
AI-driven data centers are rapidly evolving beyond traditional cloud workloads. Large-scale AI training and inference generate unprecedented east–west traffic between GPUs, accelerators, switches, and storage systems—driving network fabrics from 400G and 800G toward 1.6T.
Farsince’s Next-Gen Data Center Interconnect Solution delivers a future-proof physical layer, enabling scalable bandwidth growth without disruptive re-cabling. It is engineered specifically for Data Center & AI environments where latency, density, and long-term scalability are mission-critical.
Architecture Overview
From AI Server Nodes to 1.6T Fabric
Farsince applies a layered interconnect architecture that aligns physical connectivity with AI workload behavior:
1. Inside the AI Server / Node
High-speed internal connections between GPUs, NICs, accelerators, and storage.
2. Rack-Level Interconnect (Server ↔ ToR)
Ultra-low-latency, high-density links optimized for GPU pods and top-of-rack switching in AI clusters.
3. Fabric Interconnect (Leaf ↔ Spine / Super-Spine)
A scalable optical backbone carrying massive east–west traffic across rows and zones—forming the foundation for 400G, 800G, and future 1.6T fabrics.
4. Structured Infrastructure & Support
Management networks, power distribution, cable routing, and testing systems that ensure long-term stability and operational efficiency.
Design Principle
Build the physical cabling layer once—then scale bandwidth over time by upgrading active components, not the entire infrastructure.
