Analyzing Influence of the Transmission Medium on Timing Signals Transmitted by Hybrid Optical Transport Technologies

Rastislav Róka, Veronika Dolinayová


The contribution deals with synchronization aspects in SDH and Synchronous Ethernet timing networks utilizing optical transmission medium. First, it explains a hierarchical configuration of timing network elements, characterizes transmission features of the optical fiber, particularly its main negative influences influencing transmitted information signals. The main part is dedicated to the evaluation program created for analyzing influences of the optical transmission path on timing signals transmitted by SDH and SyncE transport technologies. At last, resultant values from the introduced evaluation program are presented and evaluated.
