Principle of Eye Diagram Experiment in Fiber Optic Communication
The eye diagram is created by superimposing multiple bits of the transmitted signal onto a single display. This creates a pattern that resembles an open eye, hence the name “eye diagram. ” The horizontal axis of the diagram represents time, while the vertical axis represents the. An eye diagram is a visual representation of a digital signal over time, formed by capturing multiple images of a signal's waveform and superimposing them over one another. Eye Pattern Tester EPS04 Tester EPS04 described here is an optimized set-up to conduct a comprehensive study of eye patterns or eye diagrams of a fiber optic digital transmission system.
