Optical module eye diagram test is a common optical test method used to measure the performance of optical modules during high-speed data transmission signal transmission, and is usually used to test parameters such as transparency, transmission distance and off-line storage of optical modules. The eye diagram of an optical module is an interlaced diagram of the photoelectric displacement waveform over a period of time collected using an oscilloscope and other equipment during high-speed data transmission, which can reflect the quality of the data transmission signal and the interference of the circuit. The name of the eye diagram comes from the appearance of the image resembles an "eye" shape, so called eye diagram.

Recently, LightCounting, a market research firm in the optical communications industry, reviewed the topic of F5.5G at the 2023 Huawei Global Analyst Conference. lightCounting introduced the 5.5G initiative, which aims to increase the speed of broadband wireless and wired connections by 5 to 10 times. f5.5G is the wired portion of the 5.5G initiative.

The main purpose of conducting optical module testing is to ensure that the performance of the optical module is reliable, meets the specification requirements, and can work stably in practical application scenarios, specifically including the following aspects: confirming the transmitting and receiving performance of the optical module: by testing the transmitting and receiving performance of the optical module, ensuring that it can transmit signals normally and guaranteeing the quality and reliability of data transmission.

According to the "January-April 2023 Economic Operation of the Communications Industry" released on the website of the Ministry of Industry and Information Technology, from January to April this year, the overall operation of the information and communications industry was stable, with telecommunications business revenue up 7.2% year-on-year and total telecommunications business up 17.6% year-on-year.

The optical module self-testing system integrates advanced domestic and foreign test instruments and equipment (optical oscilloscope, BER, optical power meter, optical attenuation meter, etc.), which are connected to PC side through GPIB bus or other bus supported by VISA (VirtualInstrument Software), and the PC side is controlled by the upper computer software system based on the virtual instrument to realize real-time control of each measurement instrument and complete the module automation test process.

Optical modules as more sensitive optical devices, often in the process of use will have many problems, for the more common problems of optical modules, have their corresponding test methods, such as visual inspection method to see the appearance, comparison method to measure the parameters to see the difference, replacement method to replace components to see the change in parameters, according to a certain bad condition to determine the fault circuit area, by hanging the structure of the optical module to determine the components of the fault, etc., then the specific What is the specific optical module testing process? Let's take a look!
