Overview of Synchronous Ethernet

Overview of Synchronous Ethernet


The synchronous Ethernet function allows a device to obtain clock signals from Ethernet bit streams of lines and then transmit the clock signals to the downstream network through the Ethernet. This function ensures clock synchronization between upstream and downstream devices.


On a data communication network, the sender needs to place pulse signals in a specific timeslot, and the receiver needs to extract the pulse signals from the timeslot. The sender and receiver must synchronize their clocks to ensure normal communication.

In the past, sites on a telecommunications network obtained accurate clock signals from the Global Positioning System (GPS) to synchronize their clocks. To do so, the network sites need to install antennas, causing high construction and security costs.

The synchronous Ethernet function enables devices to synchronize their clocks from another site through an Ethernet network or to obtain optimal clock signals from lines. This function ensures clock synchronization between the sender and receiver.


Synchronous Ethernet removes the need to install antennas to obtain clock signals from the GPS. This function reduces network construction and maintenance costs and protects national security because it does not use the GPS.
