Ultra Secure Multimode A/B Switch with Loopback

You can now order an fibre optic A/B switch with unique loopback capabilities. Using loopbacks, you can verify the integrity of your backup fibre link while still connected to your primary fibre 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.

The Ultra Secure Multimode A/B Switches with Loopback are available in latching and non-latching models. The latching switch latches mirror movement mechanically into a selected position and holds it there without the need for continuous electrical power. The non-latching version falls back to Common-to-A position if power is lost.

Latching Technology
The latching Fibre Optic Switches are a full-duplex, optical switch. The A/B switch for example can be used to connect one workstation to two different networks (one at a time) or to other remote devices. A front panel rotary style knob allows the user to select which of two ports (A or B) is connected to the "common" port on the switch. The switch operates using a unique all-optical micro-mirror movement. When you turn the rotary knob on the front of the switch to select a network, the internal micro-mirror movement redirects the optical beam from one network port to another network port by rotating a miniature mirror. This technique eliminates the need to convert optical signals to electronic signals to for switching and it is therefore transparent to data rates and protocols.

Applications
This switch is perfectly suited for applications where a selected connection must be maintained in the event of a power failure. You should use the non-latching fibre optic switch for applications requiring a switch that falls back to pre-determined connection during the loss of AC power. These switches use power only for switching the selected connection. No power is required to pass data through the switches.
