"The optical fiber and cable industry needs to actively follow the pace of international standard formulation and promote the healthy and sustainable development of the industry." At the 2019 Global Optical Fiber and Cable Conference held recently, Lin Jintong, former president of Beijing University of Posts and Telecommunications and deputy director of the China Institute of Communications, delivered a keynote speech. Published this view. He believes that the formulation of optical communication industry standards is very important. Only by developing mature industry standards can market-based products be developed and the core competitiveness of the industry formed.

"Social progress requires the market to be traction and technology to be the driving force." Lin Jintong said that the source of technology lies in research, and it must rely on the innovation labs of enterprises and research institutes in universities. At the product development stage, we must rely on the formulation of standards. At present, the industry, research, and research circles have fully realized the value of standards, because only with a mature industry standard can we gather sand and form an indestructible competitiveness.

At present, fiber optic cable products are widely used and diverse, and international authoritative organizations are conducting research on many topics. Lin Jintong said that the development of optical fibers such as G.652, G.654, and G.657 all relied on the basis of international standards to form a broad market scale. Therefore, facing the future, the industry needs to actively follow the pace of international standard formulation and form reasonable standards in order to bring the industry together and jointly promote the sustainable and healthy development of the industry.

Optical fiber optic cables can achieve long-distance transmission of tens of thousands of kilometers, and short-distance transmission of 1 to 10 centimeters. There are also a variety of types, including conventional optical fibers, multimode optical fibers, and laser optical fibers. For example, conventional optical fibers can be used in a variety of scenarios such as land, seafloor, and metro access, while multimode optical fibers can be used in chips, data centers, computer research, and other fields. There are also new types of optical fibers, such as ultra-low-loss large-effective optical fibers. Application in 5G field.

At the same time, the application fields of fiber optic cables are also continuously expanding.In addition to providing the physical transmission basis for the development of the Internet and 5G in the traditional communication field, it can also be used in industrial, medical, and defense fields, such as high-bandwidth active fiber, fiber amplifiers, Fiber laser, special fiber, fiber sensor, etc.

From a global perspective, optical communication technology and industry are developing and progressing every year. At present, international authoritative standards organizations hold several meetings each year on optical communication technology standards to study new technical directions. Jintong Lin said that the papers for the current conference covered more than ten fields, such as optical devices and fiber amplifiers, optoelectronic devices and technologies, integrated circuits and optoelectronic integration, optical communication enhancement technologies, optical transmission connections, optical communication theory, and photonics in the radio frequency field. Application, application of photonics in free space optics, advanced technology of optical network physical layer, architecture, control and management of optical network.

It is worth mentioning that at present, universities around the world are increasing their research efforts on optical communication technology. For example, Lin Jintong, for example, in the field of photoelectric detection systems, is facing three challenges, namely whether to achieve high bandwidth and high speed detection, achieve low energy consumption, reduce costs, and reduce optical frequency signals.
