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.
