Abstract
The synchronization duration is longer in 10G Ethernet application compare with previous ones due to higher performance and reliability requirement. In worse case, a 2112-bit FEC block in 10G/40G/100G Ethernet applications needs around 9 million bit cycles to achieve synchronized status. This paper introduces a faster method to synchronize the FEC block. Add a smart shift to drop less frame bits and re-use FEC decoder components can help to reduce the synchronization time to 26% compare with traditional way.
