Industry news, recently Minister of Industry and Information Technology Jin Zhuanglong said at the China-Africa Digital Capacity Building Cooperation Forum that China has strengthened the construction of digital and information and communication network infrastructure, and has built the world's largest and technologically leading fibre-optic and mobile communication network. Among them, the average annual growth rate of data centre scale in the past five years has reached nearly 30%.

October 21 news Today, in the 2023 China 5G Development Conference hosted by the Ministry of Industry and Information Technology, the Ministry of Industry and Information Technology party group members, Vice Minister Zhang Yunming introduced, 5G and other new generation of information and communication technology is to promote a new round of scientific and technological revolution and industrial transformation of the road, the Ministry of Industry and Information Technology to organise the industry all parties to know the weight of the heavy burden, know the difficulty of the difficult to overcome the difficulties, know the shortcomings and make up for the shortcomings of the shortcomings, know the new innovation, and to promote the new innovation in a solid manner 5G development has achieved positive results.

Optical communication is a technology that uses optical signals to transmit information, and it is one of the key infrastructures of the modern information society. The development of optical communication has gone through several stages, from the initial optical fibre to the current optical network, which has continuously improved the transmission rate, capacity and quality. Optical communication is a technology that lights up the future and will bring more convenience, innovation and value to human society.

SZTV News has specially planned a column entitled "New Productivity in Shenzhen - Decoding Shenzhen's New Productivity" to explore Shenzhen's vivid practice of promoting high-quality economic development by taking new productivity as a traction. The first series of the special report explores how new technologies can achieve innovation breakthroughs. The first article focuses on visible light communication and optical computing technologies that are flourishing in Shenzhen.

With the construction of new power systems, power communication networks are facing higher requirements, and it has become an urgent need for the power industry to improve network quality, expand network coverage, and achieve network security and control. Recently, Huawei's F5G power all-optical communication network solution appeared at the Sixth Electric Power Information and Communication New Technology Conference and Digital Development Forum, demonstrating the architecture and application of the power all-optical communication network based on end-to-end OSU technology, which has attracted extensive attention from the industry.

Demonstration of Tektronix's solution for 400G/800G PAM4 measurement PAM4 is a high-speed serial communication technology that can transmit more data under the same bandwidth, and is one of the key technologies to achieve the 400G/800G Ethernet standard. However, PAM4 signals also bring higher testing difficulty, and it is a challenge to measure the quality and performance of PAM4 signals effectively.

In 2020 and 2021, there is a major shift towards working from home and home schooling under the embargo policies resulting from the new Crown Pneumonia, creating a greater demand for faster, more ubiquitous, and more reliable networks. As a result, the optical module market has seen double-digit growth for two consecutive years, despite supply chain constraints and even disruptions.2022, the epidemic is gradually being brought under control globally, but some of the habits adopted during the crisis (remote working, collaboration, online media consumption) have become part of people's daily lives, connectivity is becoming a more important asset for homes and businesses, and demand for broadband continues to grow. As a result, the global optical module market continues to experience double-digit growth, although supply chain challenges remain.

A Chinese chip company said their test of 3-nanometer chip has been successful, showing that the domestic chip is not afraid of the difficulties and dangers, and actively seize the existing chip foundation, the first breakthroughs have the opportunity to promote the technology, and ultimately realize the breakthroughs from the point and then face breakthroughs.
