It seems there might be a confusion in your question. If you are referring to the technology used for transmitting data using modulated light, the term you are looking for is "fiber optic cable" or simply "fiber." Fiber optic cables are thin, flexible strands of glass or plastic that transmit data as modulated light pulses. They are widely used for high-speed data transmission over long distances due to their ability to carry large amounts of data with low attenuation and high bandwidth capabilities.

Answer : 2. "color monitor"
Explanation :

color monitor is a type of display that can adjust and display output by manipulating the Red, Green, and Blue (RGB) radiation. In a color monitor, pixels are made up of red, green, and blue sub-pixels, and by varying the intensity of these colors, a wide range of colors can be displayed on the screen. Adjusting the intensity of RGB radiation allows the monitor to display different colors and shades, providing a full spectrum of colors to the viewer. This technology is commonly used in computer monitors, television screens, and other displays to produce vibrant and accurate color representations.
