Semtech's DirectEdge™ Portfolio Enables Low-Power 400G/800G AI Data Center
Data center interconnects supporting AI workloads face unprecedented bandwidth requirements while operating under strict power envelopes. According to IDC's Worldwide Semiannual Artificial Intelligence Infrastructure Tracker, annual spending on AI infrastructure will exceed $200 billion USD globally by 2028. In the first half of 2024 alone, investments in compute and storage infrastructure for AI deployments reached $47.4 billion, representing a staggering 97% year-over-year growth rate.
"For hyperscalers running AI workloads, power has become a critical business constraint," said Weiliang Deng, director of signal integrity product marketing at Semtech. "Our DirectEdge portfolio benefits hyperscalers by bringing our industry-leading PMDs to successfully deploy LPO, while also addressing the power imperative by eliminating power-hungry DSPs. Every milliwatt saved in optical interconnects can be redirected to computational resources and we believe our LPO solutions are over 50% more power efficient than comparable DSP-based solutions. For a hyperscale data center with hundreds of thousands of optical modules, this translates to significant energy savings that can be applied to more GPU clusters for AI training and inference."
Established 100G/channel LPO Portfolio
Semtech's DirectEdge 100G per channel LPO portfolio offers complete coverage for both single and multimode fiber implementations in 400G and 800G optical modules.
