Layer 1 Network

Next Generation Layer 1 Switch

Manage Lab Connectivity and Troubleshooting Virtually


Pluribus VirtualWire switch converts media and physical topologies into virtual ones.


Pluribus Virtual Wire switch converts media and physical topologies into virtual ones.The Pluribus VirtualWire switch is a highly flexible, highly-scalable physical layer non-blocking switching matrix powered by the Pluribus Netvisor® OS. It is designed to build dynamic, high-performance lab connectivity with packet/application/link layer visibility.

VirtualWire enables an engineer to conserve time, maximize productivity, reduce costs and eliminate errors associated with manual patching. VirtualWire also allows users to store well-known physical configurations and reproduce the configurations at will for subsequent testing. VirtualWire also offers a powerful RESTful API to integrate with a customer’s own management and orchestration tools.


  • After initial wiring, Pluribus Virtual Wire acts as a virtual patch panel
  • Scalability – add switches in the Virtual Wire fabric as needed
  • Efficient sharing of expensive test tools (e.g. traffic generators), which can be dynamically moved across test environments with a software command.
  • Save cable configuration for future re-use
  • Fabric-wide flow, packet, link-layer visibility to accelerate troubleshooting of physical layer issues as well as applications
  • Significant CapEx savings versus traditional Layer 1 switches: 1/10th the cost!
  • Highly programmable – CLI, Python, RESTful API and C-based APIs facilitate rapid development
  • Media conversion copper<>fiber


  • Virtual Wire 1:1 and 1:n port association
  • Transparency to Ethernet frame and L2 protocols (CRC, Error frame, LLDP, FEX, Instant Access etc)
  • Media/Speed conversion with low latency
  • Link status tracking across Virtual Wire fabric
  • Fabric management can be done via single switch via CLI and/or API
  • Time Machine to replay TCP flows
  • Hardware-based packet filtering, packet capture in PCAP format and packet analysis with VCFcenter
  • sFlow, IPFIX support
