What is the optical module s optical eye diagram

Eye diagram testing and adjustment is an important stage to ensure that the optical module obtains the best signal. It is vividly named so because its shape resembles an open eye. To generate an eye diagram, an oscilloscope needs to measure a large volume of data and then recover the diagram from the measured. The eye diagram is a graph displayed by a series of digital signals accumulated on the oscilloscope. When the oscilloscope. In high-speed optical communication, data center transmission, and optical module testing, the eye diagram (eye pattern) is one of the most important tools to evaluate signal integrity (SI) and transmission quality.
