With the advent of the information age, data center traffic has occupied most of the world's communication network traffic. At present, optical communication technology is widely used in data centers, including server connections of several meters, and docking of data centers in many places around the world. Here, we introduce the optical ommunication technology of data center.
In the data center, the network connects thousands of servers, and all servers work together to complete work tasks. So far, the optical fiber communication industry has been developed for more than 50 years. In 1977, the first commercial fiber-optic communication system was introduced, which was 45 Mbit/s. Currently, the capacity of single-mode fiber has exceeded 100 Mbit/s. Whether it is long-distance information transmission or short-distance information transmission, fiber-optic communication can be seen. In 2008, data center demand for fiber began to surpass telecom operators, and data centers began to become the first market for fiber-optic communications.
