Why Use Taurus Ethernet Smart Cable Modules?

Taurus enables robust, easy-to-design 100G/Lane Ethernet connectivity with high reliability and maximum uptime, featuring the COSMOS’ built-in suite for advanced fleet management, security, and deep diagnostics.

Robustness

  • Extended Cable Line Rate

    Future proof scalability for 200G/400G/800G

  • Low Power

    Uses 50% less power than Active Optical Cables

  • Low Latency

    Low latency operation at <50ns

  • Security

    Advanced security features help prevent malicious attacks of unauthorized firmware loading, module diagnostics access, and configurations

Easy System Design

  • Thin Cable Gauge

    Up to 34AWG

  • Fewer Twinax Pairs

    8 pairs at 200G/400G/800G reduces overall external diameter of cables

  • Extended Reach

    Up to 7m of reach

  • Flexible Supply Chain

    Taurus Smart Cable Modules are compatible with multiple cable vendors for easy second sourcing of active cable assembly

Fleet Management

  • Quick Debug

    Self-test features enable rapid troubleshooting

  • Deep Diagnostics

    Cable-side and host-side diagnostics enable easy management of entire fleets

Use Cases

Switch-to-Server

Enabling an “Active” plus “Smart” approach to higher-bandwidth Switch-to-Server Ethernet interconnects and Switch-to-NIC bandwidth utilization
