Oscilloquartz Presents Optical Pumping Strategy to Meet New ePRTC Standard

Next-Generation Cesium Clocks Deliver Superior Stability and Holdover Performance

  • Speaker:    Alain Michaud, director, R&D and PLM, time and frequency, Oscilloquartz, an ADVA Optical Networking company
  • Topics:      Optical Cesium Beam Clock for ePRTC Telecom Applications
  • When:       Thursday, April 6, 9:15 a.m.
  • Where:      Workshop on Synchronization and Timing Systems, DoubleTree, San Jose, California, USA

The new standard developed by the ITU-T, Enhanced Primary Reference Time Clock (ePRTC), calls for significantly higher time accuracy, both in a so-called “GNSS Locked” mode as well as in so-called “holdover” mode. Achieving the highest class of ePRTC holdover, namely ePRTC class B, will require atomic clocks that can provide a significantly better frequency stability over long observation times.

At the 26th Annual Workshop on Synchronization and Timing Systems, Alain Michaud of Oscilloquartz, will show how optically pumped cesium beam clocks will come into play to meet these stringent timing needs. Optical pumping technology will enhance the performance of cesium beam clocks and enable ePRTC class B performance.
