Evaluation of Stability Performance of a Simple Time and Frequency Transfer System

SummaryIn this paper, we describe a simple system for the transfer of precision time and frequency signals over an optical fiber network at high accuracy. The system involves the use of small form modules for precision time and frequency transfer. As a proof-of-concept, we demonstrate the delivery of 1 Pulse Per Second (PPS) and 10 MHz signals at stability levels below 10 picoseconds (ps) and around 10^-14 respectively, over a 15-km long G.652 single mode optical fiber within the laboratory environment, for averaging periods of 1000 second.
