With the development of society, people's requirements for optical fiber communication are becoming more and more organized. Its ultra-high-speed, large-capacity and ultra-long-distance transmission are the specific goals of people's pursuit of optical fiber communication technology, and all-optical networks are the goals of people's pursuit.
In the process of processing information by user application switches, no all-optical network operates in bits. The routing is determined by the south wavelength. In traditional optical networks, all optical nodes exist in the form of all-optical. Although it has been achieved, electronic equipment has been used in the network nodes, which limits the continuous improvement of the current capacity of the communication network trunk line terminals. How to achieve true all-optical rigidity in the network has attracted more and more attention.
Optical communication technology plays a pivotal role in information technology. Although there will be many difficult paths in the development process, this is an inevitable trend in the communication field. From the perspective of the development trend of modern communications, optical fiber communications will become the king of future communications. The goal of all-optical networks is getting closer.
