✦ Synopsis
In the modern high-speed telecommunication networks on fiber optic (SDH standard), the long distance transmission links (e.g. a transoceanic transmission line) employ several cascaded regenerators. To ensure the synchronization of these networks, the jitter at each regenerator span has to be limited rigorously and maintained within permissible levels, according to ITU-T Recommendations and ETSI Standards. In this paper the architecture of an STM-16 line regenerator (bit rate equal to 2•48832 Gbits/s) is analyzed with particular consideration to the traffic timing characteristics. The influence of traffic timing blocks on jitter performances of the regenerator is investigated more in depth.
