Synchronous Ethernet (SyncE) is used mainly in telecom networks to provide physical layer clock delivery for frequency synchronization (aka syntonization). The cable industry has not yet adopted SyncE as a common supported functionality as IEEE1588 is more commonly used for time synchronization (mainly for DAA use cases).
Adopting SyncE in conjunction or in addition to IEEE1588 may add advantages both from a performance perspective, and from a simplicity and cost perspectives as well.
This paper will describe different use cases for both DAA RPHY/RMACPHY and mobile backhaul (LTE and 5G) where SyncE can add a true value. Analysis of performance compared to traditional IEEE1588usage will be shown and the benefits in simplicity will be discussed.
