Each mobile telecommunications network requires synchronization between its components. Deutsche Telekom Technik AG has decided to test a method developed by the AGH University of Science and Technology in Krakow, Poland, for the future monitoring of selected points in its network. It is based on optical time transmission (OTT), which has been tested in cooperation with PTB, among others on glass fiber links of Deutsche Telekom AG (DTAG). The results exceed by far the requirements of the International Telecommunication Union (ITU-T) for 5G networks.


Figure: The OTT system uses terminals for feeding in the data and at the target location. For remote locations, a number of bi-directional, inline optical amplifiers are used to compensate for signal attenuation in the fiber.
