Black Box Fiber Optic A/B Switches and A/B Switches with Loopback

If You Need Ultra-Secure, Critical-Circuit Switching, Use these Micro-Mirror Optical Devices


What's special about these network switches?

  • Allows you to switch between two networks or remote devices from a single PC using fiber optic cabling.
  • Equipped with micro-mirrors to optically transmit data port to port for mission critical environments.
  • No optical-to-electrical conversion between fiber connections, which is a trusted and secure technology.
  • Available in latching and non-latching models.
  • Click for More Features offers Black Box Fiber Optic A/B Switches and A/B Switches with Loopback. These micro-mirror optical devices are ideal if you need ultra-secure, critical-circuit switching. They are used to switch between two networks or remote devices from a single PC. These Fiber Optic AB Switches are ideal for government, healthcare, financial, or other applications where a private, data-sensitive network connects to a publicly accessible network.

These Fiber Optic A/B Switches are reliable because they use micro-mirrors instead of electronics to route data signals from one fiber optic port to the next. Unlike conventional electronic switches, there are no complex and vulnerable electronic circuits to monitor and protect from intrusion, component failure, or interference.

The switches are available in latching and non-latching models. The optical mirror movements on the latching versions maintain the selected position even when there's a power failure.

If you order an A/B switch with unique loop-back capabilities, you will be able to verify the integrity of you backup fiber link while still connected to your primary fiber link. This is especially useful in failover applications where you want to continuously test the "unused" circuit to ensure that it's available if needed.

  • Operate transparently to signal rates, formats, and wavelengths, and don't require an upgrade when your data protocols change or speeds increase.
  • On latching models, latching mirror movement mechanically maintains the selected position, even in a power failure.
  • All non-latching versions except for the SW1003A fall back to C-to-A position if power is lost. The SW1003A falls back to the OFF position, which prevents host-to-remote device communications.
  • Models with loop-back enable you to test the integrity of your backup fiber link.
  • For reliable switching in mission-critical environments, the micro-mirrors are bonded to precise positioning servos.
  • Simple to use, just turn a knob on the front panel to route signals.
