3. 1. Product Introduce This product is to transmit Video 2Ch signal through Fiber Optic Cable 1core, combining the system according to the need. It is generally called Video Link equipment. It is the method using optical characteristics, capable of no-relay long-distance transmission, and getting no influence from electric field and magnetic field. Having input and output display LED, it shows the data communication state visually. 1)High quality image transmission 2)CCTV, ITV system 3)Factory automation, Road traffic monitoring system 4)Exterior surveillance, Security system Displaying input image per each channel -.Normal (Optical cable is connected) Displaying the cut of optical cable -.Optical cable is cut. -.Checking optical cable connection status Displaying the output image value per each channel -.The value changes depending on the Image level. -. 0.8~1.2: Normal. Displaying no input image signal -.Optical cable is connected, but there is image signal. The way to check 7 segments is as follows.
