Goilips 400G/800G Leaf-Spine Architecture for Cloud Data Centers

Overview

As AI large-model training, massive cloud workloads, and high-performance computing (HPC) expand rapidly, traditional three-tier network architectures can no longer meet the demand for low latency, high bandwidth, and surging east-west traffic.

This solution is built on Goilips 400G/800G single-mode Silicon Photonics optical modules for modern hyperscale cloud data centers. Through a flattened, non-blocking Leaf-Spine architecture, it creates a high-density, highly scalable, low-power, and highly stable backbone interconnect network for data center fabrics.

Applications

Hyperscale Public and Private Cloud Data Centers

Designed for Tier-1 and Tier-2 cloud providers such as AWS, Alibaba Cloud, and Tencent Cloud that require extremely high-throughput backbone access.

AI / ML High-Performance Compute Clusters

Provides high-speed, low-latency, lossless interconnects between GPU/NPU nodes and storage clusters.

Large Enterprise Hybrid Cloud and Inter-Data-Center Backbones

Supports high-bandwidth services such as cross-Pod HD video streams and real-time distributed database synchronization.

Deployment & Architecture

In a Leaf-Spine topology, every Leaf switch connects to every Spine switch in a full mesh, eliminating the convergence bottlenecks of traditional networks.

Goilips 400G/800G Leaf-Spine Architecture for Cloud Data Centers

Leaf-Spine Short-Reach and High-Density Intra-Pod Interconnects (within 500m)

Core Deployment：Use Goilips 400G DR4 / 800G DR8 or 800G 2xDR4 modules with MPO/MTP multi-core single-mode fiber.

Advantage：Delivers extremely low power consumption and latency, suitable for high-density Spine and top-of-rack aggregation.

Inter-Pod and In-Building Medium-Reach Interconnects (within 2km)

Core Deployment：Use Goilips 400G FR4 / 800G 2xFR4 or FR8 modules with standard duplex LC single-mode fiber.

Advantage：Uses CWDM wavelength-division multiplexing to significantly reduce fiber cabling cost while providing excellent redundancy and scalability.

Cross-Campus and Cross-Building Backbone Extension (2km - 10km)

Core Deployment：Use Goilips 400G LR4 / 800G LR4 modules for multi-building hyperscale data center scenarios.

Advantage：Maintains high-quality signal transmission over extended distances without optical relay equipment.

Key Benefits

Extreme Power Management

Chip-level integration reduces power consumption by 15% to 20% compared with traditional EML modules, lowering data center PUE and saving substantial electricity costs every year.

High Reliability and Temperature Stability

Silicon-based materials provide excellent thermal stability, and the reduced optical component count improves MTBF while lowering operational risk.

High Density and Smooth Evolution

Supports OSFP, QSFP-DD, and QSFP-112 standard form factors with strong compatibility, enabling smooth upgrades to 800G and 1.6T while protecting existing switch investments.

Signal Integrity

Built-in high-performance DSP chips support PAM4 modulation and FEC forward error correction, ensuring zero packet loss and ultra-low BER across 500m to 2km transmission distances.

CapEx and OpEx Optimization

Highly integrated single-mode Silicon Photonics reduces optical chip cost, FR4 designs reduce physical fiber count, and low-power operation reduces rack power and cooling costs.
