White Paper: Synchronous Ethernet Timing Solutions -- With Narrow Loop Bandwidth And Ultra Low Output Jitter

By Param Nampoothiri, Valpey Fisher Corporation

Today's consumers demand more bandwidth and faster, more reliable services. Network providers are designing the next generation IP based networks to meet the demand and Ethernet has emerged as the transport medium of choice. For more accurate data multiplexing and de-multiplexing, IP based networks have a strong requirement for frequency synchronization across the entire network. SONET based networks have this capability already. A new solution is to take the already popular asynchronous Ethernet Network and synchronize it. This new technology is called Synchronous Ethernet or Sync-E.
