Multiband fiber polygon for accurate time and coherent frequency transmission
Havliš, O. ; Vojtěch, J. ; Šlapák, M. ; Číp, Ondřej ; Čížek, Martin ; Hrabina, Jan ; Pravdová, Lenka ; Slodička, L.
The CESNET association, in cooperation with the Institute of Scientific Instruments of the Academy of Sciences of the Czech Republic (Institute of Scientific Instruments of the CAS, abbreviated ISI CAS), ČD Telematika and University Palacký in Olomouc (UPOL) Department of Optics built a multiband polygon on real optical routes . The multiband polygon is designed for two-way transmission of ultra-stable quantities, i.e. transmission of acurrate time and coherent frequency (T/F).

The poster describes the infrastructure for transmission of accurate time and coherent frequency using multiband, i.e. in a dedicated part of the optical spectrum in C, L and S bands, where bidirectional transmission is carried out on the in-house developed Czech Light system.
