Photonic Services with Sensor System in One Fibre with 100-GHz DWDM Grid

Optical fibers allow more than high bandwidth for common services such as video and data transmission. The scientific community investigates optical fibers due to their delay value for photonic services, which require minimum conversions from the optical to the electrical domain. Optical fibers are used widely around the world, and with the decreasing price of optical components, it is possible to use optical fibers for infrastructure protection without any interruption of service. This article presents the measurement results for simultaneous transmission of two services with a sensor system according to the 100-GHz grid defined by the International Telecommunication Union. The results confirm that the 100-GHz grid is not sufficient.
