The eye diagram of the optical module is very poor
The key parameters used to judge whether an eye diagram is normal include eye height, eye width, jitter, and extinction ratio. For beginners, this might sound confusing—but don't worry. You will also get practical selection criteria, common failure modes, and a head-to-head decision matrix for choosing test setups. The eye diagram test is an indispensable methodology for evaluating the signal integrity and performance of high-speed digital communication systems, particularly in the domain of optical transceivers. The diagram is generated by overlaying multiple traces of a signal on an oscilloscope.

The function of the photoresistor tracking module
The KY-018 Photoresistor module is used to measure light intensity. It can be used for various purposes, such as adjusting the brightness of a device, detecting day and night, or activating a light switch. Compatible with many popular microcontrollers like Arduino, ESP32 and others. The module supports analog output and digital output, equipped with a power indicator light, a signal indicator light, and a potentiometer for adjusting the light the digital output. The module typically consists of a photoresistor (also known as an LDR or Light Dependent Resistor) and additional circuitry to make it easier to interface with. The Photoresistor module is a light sensor based on a photoresist, also known as a light-dependent resistor (LDR) or photocell, which is a type of resistor that changes its resistance in response to the intensity of light falling on it.
