Ethernet Ring Protection Switching (ERPS) for Uninterrupted Performance and Swift Recovery

ERPS in networking provides a cost-effective solution to enhance network redundancy and uptime during a network link or node failure. Essentially, if a network node fails, the network traffic can quickly and seamlessly be rerouted to maintain network connectivity. ERPS is ideal for critical workloads where even a few seconds of downtime can have significant consequences. It seamlessly integrates network rings without disrupting the existing infrastructure.

  • Prevents network loops and broadcast storms within the ring topology.
  • Provides network recovery within 50 milliseconds, minimizing packet loss caused by link failure.
  • ERPS-capable devices from different manufacturers can seamlessly communicate within a ring.

SFP 2.5G Speed and Tri-Speed Range Redefine Network Connectivity

Up to 2.5G Uplink

Boost network speed seamlessly without altering existing infrastructure, catering to the heightened demands of 2.5G devices. A cost-effective alternative to 10G connections, ideal for bandwidth-intensive applications.

Tri-Speed Range

Tri-speed ports (100M, 1G, 2.5G) offer versatile connectivity, enabling devices to run at different speeds over existing connections. Effortlessly scale network capacity for expanding bandwidth needs.
