This product transmits four video channels between the camera and monitor and a bidirectional control data channel between the control keyboard and the receiver box using one fiber optic cable.
It is a WDM (Wavelength Division Multiplexing) method that utilizes optical characteristics to transmit long-distance wirelessly and is not affected by electric and magnetic fields.
LEDs for data input and output indication are attached to the transmitting and receiving parts, so you can visually check the data communication status without separate equipment, and the video transmitting and receiving parts use seven-segment LEDs to check the video input and output voltage and optical cable disconnection in real time.
