Broadband optical communication has become a soft rib optical communications, optical devices and optical chips into to breakthrough direction: in this week's light fair, telecommunications professor wei in-depth analysis of the optical communication industry in China in the market opportunities and challenges. In application and business level, in the past decade, and the next five years, our country traffic growth will remain above 40% is far higher than the global average of 22%, the future 4 k, 8 k, VR/AR, the popularity of new technology such as automatic driving, 5 g will continue to promote the flow of high growth, so as to promote the sustainable development of the optical communication and also led to the current optical communication bandwidth become soft rib optical communication. In addition, optical communications core technology in China is weak, industrial chain big but not strong, the core device chip, materials, instruments, light manufacturing platform in areas such as the gap is bigger. Optical device is less than 15% global market share. Development direction in the future, optical communication on the other hand is a network architecture to SDN/NFV open cloud of software and hardware decoupling network architecture; On the other hand is the silicon photonics, new generation optical fiber will lead to the physical layer technology innovation. In the development of optical communication, optical device costs 70% to 80% of the total cost has become a development bottleneck, and the light chip is to be the most important breakthrough. In addition, the emergence of silicon photonics technology brought hope to breakthrough the bottleneck of optical devices, recommend attention in optical devices and silicon light son has deep accumulation in the field of optical communications technology, ZhongJi equipment, etc.
