In the data age, there are more and more high-density and high-bandwidth applications. At this time, passive optical cables or copper-based cable systems appear to be stretched. In order to ensure the stability of transmission and flexible application, users urgently demand a new product as the main transmission medium for high-performance computing and data centers. Under this situation, active optical cable products have emerged at the historic moment. With the irreversible trend of "optical advancement and copper retreat", the future will be the age of "all-optical networks", and active optical cable technology will penetrate into every corner of the high-speed interconnection market.
