High Density, Low Power, and Cost-Effective — Powering the Next Generation of Data Center Upgrades
April 15, 2025 Singapore – FIBERSTAMP, a global leader in optical communication solutions, has launched a new cost-effective short-reach data center interconnect solution: the 400G QSFP-DD SR4 to 4×100G single-lambda QSFP28/SFP112 SR1.
Designed to meet the growing demands of modern data centers for higher speed, greater density, and lower costs. This innovative solution significantly reduces deployment complexity and total cost of ownership (TCO) through an advanced architecture. It offers a flexible and efficient connectivity option for cloud computing, AI clusters, and hyperscale data centers.
Key Highlights of the Solution
High-Density and Flexible Scalability
- Utilizes a 400G QSFP-DD SR4 optical module as the uplink port, branching into four independent 100G QSFP28/SFP112 SR1 downlink connections via single-mode or multimode fiber. This enables 1:4 non-blocking transmission, boosting single-port bandwidth utilization by 300% and significantly conserving switch port resources.
- Fully compatible with mainstream data center Top-of-Rack (ToR) architectures and supports leading switching platforms such as NVIDIA and Broadcom.
Breakthrough in Single-Lambda Technology
- Powered by FIBERSTAMP’s proprietary single-lambda 100G PAM4 modulation technology, this solution overcomes the limitations of traditional parallel multi-fiber approaches.
- It enables stable 100-meter transmission over OM4 multimode fiber while reducing power consumption by 20% compared to similar solutions—meeting the stringent energy efficiency demands of short-reach SR applications.
Cost-Effective Deployment
- Compared to traditional 400G full-optical module networking, this solution reduces the number of high-speed optical-electrical conversion units by up to 75%, significantly lowering equipment procurement costs.
- 100G single-lambda transmission minimizes fiber usage, further cutting down overall infrastructure expenses.
- Supports hot-swappable, plug-and-play operation with no need to modify existing cabling infrastructure—dramatically shortening deployment cycles.
Full-Spectrum Compatibility
Downlink ports can be flexibly configured with either 100G QSFP28 SR1 or 100G SFP112 SR1 modules, ensuring compatibility with both existing 100G infrastructure and emerging single-lambda standards—safeguarding customer investments.
Application Scenarios
- AI/GPU Cluster Interconnects: Efficiently links high-performance compute nodes while reducing latency and power consumption.
- Cloud Data Center Spine-Leaf Architectures: Optimizes east-west traffic and alleviates bandwidth pressure at the core layer.
- Storage Network Upgrades: Seamlessly supports high-speed storage protocols such as NVMe over Fabrics.
Amid the explosive surge in AI and computing power demands, the demand of high-performance, cost-effective 400G/100G interconnect solutions has never been more urgent. FIBERSTAMP’s cutting-edge design delivers the ideal balance between performance and affordability, empowering data centers to make a seamless, future-ready transition to next-generation network architectures—while minimizing capital investment.
