  • LAN
  • Ideal for government, health care, financial, or other networks that require switching to alternate paths
  • Optical network testing and analysis


The SwtichBox™ Mechanical Fiber Optic A/B Switch is a device that accepts optical inputs from a primary path and a secondary path to provide manual switching in the event that the primary path signal is broken or otherwise disrupted.

Easily switch both transmit and receive fibers to a backup path. No optical to electrical conversion between the fiber connections, no mirrors or substrates and no power required, resulting in a Failsafe Network Switch. Extremely low loss, low back reflection, and infinite crosstalk. Ideal for simultaneous network protection of both transmit and receive paths.

The switch can also be used in a variety of other custom configurations - network simulators, delay lines, add/drop switching and latency switching.
