Over the past 100 years, mankind has evolved from simple telegraph communication to today's 5G communication, and life has changed dramatically with increasingly widespread applications such as live streaming, VR / AR, ultra-HD video conferencing, telemedicine, autonomous driving and smart homes. And all of these need to be based on high-speed data transmission.

It is reported that the 2022 common fiber optic cable products centralized procurement project procurement scale of about 31.03 million skin length kilometers (equivalent to 846.7 million core kilometers), specifications for GYTA / GYTS / GYTA53, etc., the project funding source for self-financing 7.11 billion yuan, the bidders for China Radio and Television Network Corporation, the bidding content for ordinary fiber optic cable and cable processing Part.

In 2015, the competitive landscape of the optical module market was highly fragmented, with less than 20% of the market share held by the leaders and single-digit market shares held by the remaining vendors. However, with the development of technology, research and development and expansion threshold continues to improve, the scale advantage of large leading manufacturers is becoming more and more significant. In addition, in recent years, optical module companies have accelerated mergers and acquisitions, vertical integration of the industry chain, and further increase the concentration of the industry, the global optical module market will gradually move toward concentration.

Higher technical barriers and complex processes, optical chip in the optical module cost accounted for a relatively high. The main body of TOSA is the laser chip (VCSEL, DFB, EML, etc.), and the main body of ROSA is the detector chip (APD/PIN, etc.). (APD/PIN, etc.).

Optical Module (Optical Module) consists of optoelectronic devices, functional circuits and optical interfaces, etc. The optoelectronic devices include two parts: transmitting and receiving. The role of the optical module is photoelectric conversion, the transmitter side of the electrical signal into optical signals, through the fiber optic transmission, the receiver side and then convert the optical signal into electrical signals.

Recently, the Ministry of Science and Technology and six other departments issued a document, focusing on creating a number of major scenarios to expand the application of artificial intelligence, high-level scientific research activities is one of them. Today, China's rapid development of artificial intelligence technology, in data acquisition, experimental prediction, results analysis and other aspects of advantage, life sciences, mathematics, chemistry, space science and other disciplines of research have embraced artificial intelligence. Rich application scenarios also feed the development of technology and promote industrial intelligence upgrading.

Recently, the first 29 gigabit cities across the country were officially unveiled, showing the latest achievements of China's gigabit optical network construction, while 2022 will usher in the peak of gigabit city construction. As an important basic material for the construction of gigabit cities l

Deep plowing test and measurement industry for decades or even longer is the German technology, Tektronix, R & S, NI, Anritsu several major brands although there are many macro commonalities, but each has its own characteristics, highlighting the respective advantages of each in the industry focus, but also the overall presentation of the current industry hot spots and the strategic response to each characteristic. Look at the first half of 2022, the test and measurement industry are staged in what the big show it.
