At present, China's gigabit optical network construction and deployment has entered a rapid development phase, and has achieved global leadership in four aspects: technology level, network capacity, industrial ecology, and user scale. As of the end of the first quarter of 2023, China has 110 million broadband gigabit or more users, 17.93 million 10G PON ports, gigabit optical network has the ability to cover more than 500 million households, the network scale and coverage level ranked first in the world. Currently, domestic telecom operators have focused on the new direction of gigabit optical network technology evolution, and continue to explore the application of gigabit optical network in different scenarios through research and development, trials to find new market opportunities and development paths.

If we consider these four years as the "first half" of 5G development, the achievements of 5G in China are obvious to all. But under the reputation, the future development of 5G still faces great challenges, and how to solve the problems encountered in the development, or problems, will be the first task of the "second half" of 5G, which is related to the success or failure of 5G.

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.
