This Thor Broadcast F-4CC-TxRx 4 Contact Closure or TTL over Fiber kits that allow you to send electrical signals over fiber optic cable.

This works exactly like a relay - electrical on/off switch than can be controlled from the transmitter to the receiver or in both directions, for example if we will close or short 2 pins on the TX side it will close it on the receiving side which allows the current to flow, so you can turn off or turn on any device remotly over fiber. You can also send 5Vpp TTL pulses or signals.

The base unit works for 20Km over single-mode fiber or 3000 feet of multimode fiber - ST/PC fiber connectors

They are typically used in applications with Access Control System, Alarm Event Triggering, Building Automation, and Environmental Control Systems, Fire & Alarm Systems, PIR signal Transmission, Traffic Signal Control Equipment, etc, and are available for stand-alone or rack-mount installations. ST/PC is standard; please call or ask your representative about SC or FC optical connectors if needed.

Plug and Play design ensures adjustment-free installation and operation, and optical adjustments are never required. LED indicators are provided to instantly monitor the system operating status
