Jitter and Wander in SyncE

Testing Jitter and Wander to ITU-T Standards


Though jitter and wander are closely related, their effects on networks and devices are quite different. Jitter directly causes bit errors at device inputs by the eye-closure mechanism.These bit errors then result in dropped packets. Wander does not impact the input stage but affects the ability of the internal clocking function to lock to and track the up-stream reference. Wander therefore impacts the distribution of clock references across networks.
