Pro Switching System

The Pro Switching System is an intelligent Layer 1 A/B gang switching, chassis-based solution that does not look at data, only at physical connections, like an “intelligent patch panel.”


Advantages of Layer 1 vs. Layer 2/3 switches

  • Less complex, more reliable. Easier to install.
  • No misconfigured network protocols.
  • No firmware or software upgrades to manage.
  • Independent of data rates, formats, and protocols, so they're future-proof investments.
  • Air-gap isolation means inherently secure network connections, especially important in military, government, and other high-security applications.
  • System continues to pass data even when powered off, making it a “green” solution.
  • Highest performance: CAT6 supports 10GbE, or use fibre at the speed of light.

What makes Pro Switching different?

The Pro Switching System uses proprietary micro-mirrors and relays to provide electrical/optical continuity through the connected path and true air-gap isolation in the disconnected path.

It's transparent to data rates, formats, and protocols.

It continues to pass data even without power.
