SFP Optical Module LPO

Certified LPO (Linear Pluggable Optics) SFP modules offer low-power, low-latency, and host-compatible optical connectivity for high-speed data centers and AI/HPC networks.

Overview of LPO Technology

Linear Pluggable Optics (LPO) are optical transceivers that remove the DSP (Digital Signal Processor) from the module, replacing it with high-linearity analog components such as transimpedance amplifiers (TIA) and driver chips. Signal processing is shifted to the host ASIC, which reduces power consumption, lowers latency, and simplifies thermal management compared to traditional DSP-based modules.

O modules are particularly suited for short-reach, high-density connections in AI/ML clusters, GPU fabrics, and hyperscale data centers. Key BenefitsUltra-Low Power Consumption: LPO modules can reduce power usage by up to 50% compared to DSP-based modules, e.g., FS 800G LPO DR8 consumes only 8. 5W.

Reduced Latency: By offloading signal processing to the host, LPO modules minimize delays, improving synchronization in AI/HPC workloads. Simplified Thermal Management: Lower power translates to reduced heat generation, easing cooling requirements in dense deployments. Cost Efficiency: Fewer components in the module reduce manufacturing costs and total cost of ownership.

Certification and InteroperabilityLPO modules are designed to meet multi-source agreements (MSA) standards, ensuring interoperability across different vendors and network equipment. EU-tested LPO modules undergo independent validation for power, signal integrity, and interoperability, with downloadable test summaries available upon verification. Certification ensures that modules are host-ready and compliant with CEI-112G-LINEAR-PAM4 standards, making them suitable for deployment in certified data center environments.

Use Cases

Data Centers: High-density leaf-spine networks where low power and high port density are critical. AI/HPC Clusters: GPU fabrics benefit from reduced latency and improved synchronization. Telco Networks: Efficient, low-latency optical interconnects for 400G/800G deployments.

Considerations

Host Compatibility: LPO modules require host ASICs capable of handling linear signal processing. Compatibility must be verified for each platform. Link Distance: LPO is optimized for short-reach connections; DSP-based optics may still be preferred for longer or less predictable links.
