QuickSwitch Model 4181 Fiber Optic Auto Fallback Switch With Remote Control

FOR IMMEDIATE RELEASE 

Electro Standards Laboratories (ESL), Cranston, RI, has just developed its new QuickSwitch Model 4181 to automatically detect a faulty line and to switch to a backup/secondary fiber optic network. The QuickSwitch 4181 SC Duplex A/B 100 Base-FX Auto Fallback Switch operates as a Fallback Switch and A/B Switch.

As a Fallback switch, the Model 4181 monitors its environment for SD (signal detect) to determine its switch position. If the primary link is lost, the unit sends an alarm notification; when the fiber link is restored, an acknowledgement is sent. The Model 4181 maintains connection from the Common port to port A while SD is present on the A port. If SD is absent or lost, the unit automatically switches to the fiber link connected to port B. Once SD has been restored and is sensed at port A, the switch automatically returns to the A position. The unit can be setup to respond differently to the loss and recovery of the primary fiber link A.

As an A/B Switch, the Model 4181 can be switched from its front panel pushbutton, or remotely by communicating with the unit via its Remote Control Supervisory Port located on the rear panel.

Model 4181 is also featured on Cabling and Installation Maintainance website.
