Power, latency and cost. The three horsemen of Artificial intelligence (AI) and Machine Learning (ML) data center interconnects.  Each new generation of interconnect drives a lower mW/Gbps and dollar/Gbps. Power consumption is not just about data center operating expenses. It is also about sustainability. 

Enter Linear Pluggable Optics (LPO) links. Harnessing the power of an innovative Linear Drive architecture, LPO links are here to drive innovation across power, latency and cost like never before.  

LPO links can significantly reduce module power consumption when compared to traditional Digital Signal Processing (DSP) based solutions, without compromising performance. This also comes with the benefit of reduced cooling costs. 

By not retiming the data, latency is significantly reduced, enabling faster data transfer times during AI model training and inference – critical for accelerating AI performance. 

Swapping from DSP-based solutions to LPO translates into significant cost savings, driving down capital expenditure. Operational costs are also driven down by lower power and cooling costs. 

At this year’s OFC 2024 exhibition, Semtech showcased a plethora of technologies aimed at innovation and technological leadership. The highlight? The next-gen 400Gbps and 800Gbps LPO modules demonstrating remarkable compatibility and scalability. 

In conclusion, these LPO links are not just redefining the capabilities of AI and ML data center interconnects, but they are also paving the way for a more connected, sustainable, and tech-intelligent future.  

So, if you're into data center management or network engineering, keep an eye on this space. The future is intelligent, interconnected, and at Semtech, it's happening now!
