Fraunhofer researchers, in collaboration with partners, have optimized data transmission in fiber optic networks using smart techniques. Optical switches with liquid crystal mirrors reduce data packets, allowing more data to pass through the network. Additionally, splitting signals across various fiber strands creates more flexibility.

The project WESORAM has developed a technology that allows signals from eight input channels to be sent to 16 output channels, increasing network capacity and flexibility. The research also includes the development of signal amplifiers for multi-core fibers, enhancing data transmission capabilities.

Both projects are supported by the German Federal Ministry of Education and Research and the VDI (Association of German Engineers).
