Abstract :
A two-way time and frequency transfer technique using SONET (SDH) protocol is described. The system has demonstrated stabilities of 10 ps in "loopback" configuration. Preliminary measurements on a system performing full two-way time transfer shows stabilities of better than 100 ps at 100 seconds, limited by flicker phase modulation.
