Synopsys and TeraSignal have reached two milestones in optical networking, demonstrating seamless interoperability for PCIe 6.x and 112 Gbps Ethernet over linear optics.

These industry-first achievements highlight the potential of linear optics to transform data transmission in hyperscale data centers and high-performance computing (HPC) environments.

Linear optics: Faster data transmission with less power consumption

Copper cables — the traditional backbone of data transmission — are struggling to meet the speed, power efficiency, and performance demands of modern computing environments and workloads.

Linear optics offer a compelling alternative, providing faster data transmission over long distances with less power consumption and minimal signal loss.

  • No retimers or DSPs: Linear optics eliminate the need for power-hungry components like retimers and digital signal processors (DSPs).
  • Efficiency gains: Linear optics can reduce power consumption by up to 50%, lower latency, and generate less heat compared to legacy cabling infrastructure.
  • Simplified design: Linear optics simplify the data path, making it ideal for hyperscale and HPC environments and demanding applications like artificial intelligence (AI) and machine learning (ML).
