Time and Frequency
We all know about Time is precious. Frequency is the inverse of time (f = 1/t, 1 Hz = 1/1 sec). Both parameters are correlated. Anyone who have studied communication would understand the time domain versus frequency domain, and its relationship.
What is Netsync
Netsync stands for Network Synchronization. Netsync is referred to both Frequency Synchronization and Time Synchronization. Netsync is the heartbeat to a modern digital communication network, such as your Internet, 3G/4G/5G mobile cellular network, enterprise IP network, SDH/all-IP backhaul transmission network. In fact, this heartbeat is everywhere.
How important is netsync to a digital network?
This is like you are asking a question on how important is your heartbeat to your body and your health? When your heartbeat stops, you will die. When your heartbeat is not beating regularly at the right frequency, sometime too fast, sometime too slow, or a sudden heart attack (we call it a phase jump in Netsync), what will happen to your health or what warning your body is giving to you? It is exactly the same kind of questions you would ask to a Netsync expert - how important is Netsync to a digital network.
Netsync is very specialized
Netsync is indeed a very specialized field of communication technology. Not many datacom engineers, network engineers or computer professionals are familiar with the concept and applications, let alone the technologies, products and measurement aspects. However, it is a very important subject as our communication is moving towards higher and higher speed - from Mega- to Tera- bits per second, in terms of second (period, 1 over frequency), we are talking about nanosecond or picosecond of variation! A timing difference or variation of a few nanoseconds can make the world turned upside down.
