Abstract
Time transfer systems and methods implemented in a first node steps of communicating a stream of encoded blocks with a second node; and communicating synchronization messages with the second node via a synchronization message channel in overhead associated with the stream of encoded blocks, wherein the synchronization messages are utilized for synchronization of a clock at the second node. Each block in the stream of encoded blocks can be one of a data block and an overhead block.
