Jitter and Wander
Jitter and wander are essentially short and long term signal rate movements across networks. SONET/SDH are, by definition,synchronous systems which require phase stability in clock and data signals throughout the network. Network elements (NE) are subject to a number of interference factors that can affect synchronisation and transmission quality, resulting in bit errors, slips and data loss. Jitter and wander measurements are deployed to quantify these errors and enable network operators to maintain synchronicity within acceptable limits.
