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.

August 10 (Shui Yi) learned from the China Trade Remedy Information Network (CTRIN) that on August 3, 2023, India's Department of Revenue, Ministry of Finance, issued Circular No. 07/2023-Customs (ADD) stating that it accepts the recommendation of India's Ministry of Commerce and Industry (MoC&I) for the affirmative final anti-dumping ruling on May 5, 2023 on non-dispersion shifted single mode optical fibers ["DISPERSION UNSHIFTED SINGLE MOTHERED OPTICAL FIBERS (DISMOS) "SMOFs"] originating from or imported into China, Indonesia, and the Republic of Korea.

Optical communication is a communication technology based on the transmission of optical signals, while fiber optic communication is a communication method that uses optical fiber as a transmission medium. Spectral analysis plays a crucial role in optical and fiber optic communications, which can accurately measure and analyze optical signals to ensure the stability and performance of the communication system.

With the rapid development of cloud computing, big data and other technologies, the scale of data centers is getting larger and larger, and the demand for higher data transmission rate and bandwidth is becoming more and more urgent. And optical interconnection technology, as an efficient and reliable data transmission method, is favored by many data centers.

The Yestech Keysight 81607A, 81608A and 81609A tunable laser sources, a series of modules for the Yestech 8164B optical wave measurement system. The new modules extend the product line introduced in 81606 2015 with the introduction of the Keysight <>A Tunable Laser Source, an instrument with unmatched subpico-meter tuning repeatability and best-in-class wavelength accuracy, even in full-speed bidirectional scanning.

The 14th Five-Year Plan for the development of the information and communications industry calls for accelerating the construction of "double gigabit" networks and building a new digital infrastructure system, and gigabit optical networks are the very topic. China has built the world's largest, technologically advanced optical network infrastructure, gigabit access capacity covering all prefecture-level cities, gigabit optical network has the ability to cover more than 500 million households.

As the world's first country to commercialize 5G, Korea's R&D layout for 6G continues its global leadership position. On the one hand, Korea is at the forefront of 6G research top-level design, and the government has strongly supported and set the goal of early commercialization of 6G. On the other hand, Korea's local telecom equipment vendors and operators are working together to rapidly advance technology iterations and updates, as well as to continue cross-border cooperation.
