Maintaining Accurate Time within Facebook Datacenters
Facebook produces some of the most popular websites and apps in the world. Their technologies empower over a billion people around the globe and a crucial enabler for this is their network of datacenters. Read how Facebook synchronized all their servers across many datacenters with sub-millisecond precision and how they were able to improve timing synchronization accuracy from 10 milliseconds to 100 microseconds.

BRIEF
Making Over-the-Air Sync Measurements
Much has been done to accurately measure the time error associated with network equipment, however, measuring the time error of a 5G NR or 4G LTE base station with no 1pps output is a challenging problem. One option is to make a measurement of the downlink radio signal. This technology brief describes how to make such an over-the-air “time error” measurement by decoding and examining the synchronization signals and comparing them to an external time reference.

WHITE PAPER
Jitter and Wander in SyncE
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.
