Electro Standards Laboratories is now shipping the QuickSwitch Model 4181 fiber optic auto fallback switch with remote control.

As a fallback switch, it monitors its environment for SD (signal detect) to determine its switch position. If the primary link is lost, the unit sends an alarm notification and when the fiber link is restored, an acknowledgement is sent.

As an A/B switch, the Model 4181 can be switched from its front panel pushbutton or remotely by communicating with the unit via is Remote Control Supervisory Port located on the rear panel. The unit can be set up to respond differently to the loss and recovery of the primary fiber link A.
