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.

keysight will explore the rapidly evolving technologies that are reshaping the human experience: innovation at keysight World: Innovation, the company's annual visionary conference for technology leaders, engineers and innovators. Industry leaders and futurists will share actionable insights on 6G, <>G, software-defined vehicles (SDV), non-terrestrial networks (NTN), and digital healthcare.

How well do statistical models predict the behavior of real-world systems? In many signal integrity applications, such as estimating random jitter at a given bit-error-rate (BER), a given aggregate of statistical distributions is used to infer potential future outcomes. Similarly, Figure 1 depicts a model that predicts the ratio of the histogram range to the histogram sigma (one standard deviation) for various overall sizes of a Gaussian distribution. The predictions indicate that the limits of the range to sigma ratio increase as the population grows.

LightCounting, a leading market organization in the optical communications industry, has announced the latest version of its 2022 Global Optical Module Top 10 list. The list shows that Chinese optical module manufacturers are getting stronger, with a total of seven finalists and only three overseas remaining on the list.

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.
