Cabling Project for National-level AI Computing Hub in Southeast Asia
Case 1: Cabling Project for National-level AI Computing Hub in Southeast Asia
(Corresponding Solution: Global AI Computing Power & Big Data Center Cabling Solution)
Project Name: National-level AI Computing Center Project (E-class Computing Cluster) in a Southeast Asian Country
Project Background: Built for large model training, cross-border AI inference and supercomputing scientific research. It is equipped with over 12,000 GPUs, adopts 400G/800G backbone network and Spine-Leaf non-blocking architecture, requiring 99.999% availability and non-stop operation all year round.
Core Challenges: High-density 400G/800G interconnection, latency below 1μs, high concurrency of ten-thousand-card-level clusters, PUE ≤ 1.25, and adaptation to tropical high-temperature and high-humidity environment.
Dingliang Solutions
- Backbone network: OS2 single-mode fiber plus MPO/MTP 24-core pre-terminated cable, supporting smooth upgrade from 400G to 800G.
- Inter-rack connection: OM5 multimode MPO fiber, realizing 800G parallel optical interconnection within 30 meters.
- In-rack layout: Cat8 40Gbps high-speed copper cables plus DAC/AOC cables for direct GPU connection with low latency and high stability.
- Full-link Fluke certified products with LSZH material and Class B1 flame retardant property, suitable for high temperature and high humidity conditions.
Implementation Results
- The parallel efficiency of thousand-card clusters exceeds 92%, and the training speed is increased by 45%.
- Stable end-to-end latency below 0.8μs with nearly zero packet loss and zero failures throughout the year.
- PUE is controlled at 1.22, winning the local green data center certification.
