Why Use Taurus Smart Signal Conditioners?

Flexible 200G Ethernet, UALink, and ESUN connectivity for scale-up and scale-out

Flexibility

  • Design Once, Decide Later

    Smart Swap between lower-power Smart Redrivers and higher-reach Smart Retimers without board redesign as channel requirements evolve

  • Optimize Signal Integrity

    Taurus gives designers the flexibility to choose the right signal conditioning approach for each link, optimized for reach, power, and cost  

  • Enable Supply Optionality

    OCP Signal Conditioner Standard Footprint compatibility paves the way for supplier flexibility

Scalability

  • Scale with One Software

    COSMOS provides one unified software stack to configure, validate, monitor, and deploy Taurus Smart Retimers and Smart Redrivers

  • Extend Signal Reach

    Taurus supports flexible reach extension across AI interconnects with 40 dB+ for Smart Retimers and up to 23 dB for Smart Redrivers

  • Deploy Across AI Architectures

    Taurus Smart Signal Conditioners support Ethernet, UALink, and ESUN connectivity across dense backplane and front port reach extension applications 

Resilience

  • Improve Link Visibility

    Enhanced diagnostics, plus advanced intelligence for Smart Redrivers, give teams deeper observability to monitor link health and accelerate troubleshooting

  • Secure Infrastructure

    Advanced security features help protect against unauthorized firmware loading and other infrastructure attacks

  • Deploy with Confidence

    Built on the legacy of Astera Labs’ widely deployed, field-tested Ethernet Retimer and SCM portfolio, Taurus helps reduce deployment risk
