Optical module eye diagram is too poor no error messages
If there is no contact, the indicator of the eye diagram meets the standard, but if the tested eye diagram exceeds the standard eye diagram, the optical module cannot pass the test and additional calibration must be performed, and targeted improvements can be made. I have included the captured eye diagram of one of the good signal and one bad signal. The resulting image takes on a distinct eye-like shape, from which engineers can discern important signal characteristics.

What is the sampling waveform of an eye diagram
Typically, eye diagrams are composed of voltage/time samples of the original data, acquired at some sample rate that is orders of magnitude below the data rate. The eye diagram reflects that the digital signal is affected by the physical device and the channel. Engineer can quickly obtain the measured parameters of the signal in the product to be tested through the eye diagram, and can predict the problems that may occur in the field. For sampling oscilloscopes, this can be 105 samples per second at a 10 Gb/s (1010 bits/second) rate. PLTS constructs measurement-based eye diagrams (or patterns) by convolving the calculated time domain impulse response (generated from frequency domain measurement data) with a synthesized pattern of bit sequences.

Working principle of fiber optic array sensors
A fiber optic sensor measures a physical quantity by modulating the intensity, spectrum, phase, or polarization of light traveling through the optical fiber system. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time. Optical fiber sensors (OFSs) have emerged as essential tools in the monitoring of physical, chemical, and bio-medical parameters in harsh situations due to their high sensitivity, electromagnetic interference (EMI) immunity, and long-term stability. Fiber optic sensors play a key role in developing the communication system to sense & measure the change within phase, data transmission rate, wavelength, intensity, noise, uneven environmental conditions, extreme heat, high vibration, etc.
