Industry's longest holdover with the OSA 3350 SePRC™ optical cesium clock

  1. 1. Industry’s longest holdover with the OSA 3350 SePRC optical cesium clock December 2022 Record-breaking protection for critical network infrastructure
  2. 2. 2 Evolution of cesium atomic clock technology Performance Time Legacy magnetic cesium clocks 1990 2020 2022 OSA 3350 ePRC+ Optical cesium atomic clock innovation OSA 3300-HP Future innovation • Applying superior optical cesium technology • Major performance improvements • OSA 3350 SePRC* optical cesium atomic clock innovation will replace legacy technology • Designed for GBaas/TaaS** and more OSA 3350-SePRC OSA 3350 SePRC *Super enhanced primary reference clock **GNSS-backup-as-a-service/time-as-a-service
  3. 3. 3 OSA 3350 for demanding applications in TaaS and GBaaS Telecommunication network reference • Telecom and mobile operators (ePRTC) • TaaS/GBaaS aPNT and critical infrastructure • Power utilities, railways, transport, airports • Defense Enterprise / data centers (ICPs) / finance • Synchronization of distributed databases • High-frequency trading • TaaS and GBaaS providers Metrology, standard labs and scientific networks • Time scale networks and calibration services • Time references Markets for cesium atomic clocks
  4. 4. 4 OSA 3300/50 – key applications PTP, NTP BITS, PPS, SyncE Metrology, timekeeping institutes, science labs, providing ultra-precise TaaS/GBaaS offerings PRC/ePRC and ePRTC for communication and cloud service providers Space navigation augmentation systems and defense applications
  5. 5. 5 Resilient PNT mandate/standard update
  6. 6. 6 Atomic clocks for resilient critical infrastructures Governmental response Solution Problem Highly stable atomic clocks are key to national interest Jamming and spoofing are a major risk to business continuity in power networks e.g., Galileo e.g., GPS Dual constellations Packet network GPS Atomic clock Redundancy and terrestrial sync delivery from atomic clocks providing highly stable timing signals Executive order on strengthening national resilience through responsible use of positioning, navigation, and timing services - February 2020 PRTC ePRTC
  7. 7. 7 Optical cesium achieves superior performance Midterm advantages for optical cesium due to synergies with photonic assembly Both cesium clock technologies apply proven, highly reliable components Optical cesium improves the utilization of Cs atoms, leading to longer lifetime ADVA optical cesium technology outperforms legacy magnetic solutions Optical and magnetic cesium Lifetime Performance Reliability Production
  8. 8. 8 Everything you need: power supply and optional NMS • Outperforms ITU-T G.811.1 ePRC specification • 10 years of operation – no compromise between lifetime and performance • Combined with OSA core grandmaster: SePRTC for outstanding holdover +/- 100nsec for 55 days • Wide range of interfaces (BITS, 1PPS, analog …) • Fully supported by ADVA Ensemble Controller management system • Remote and secured management using SNMPv3 for ease of integration into third-party NMS • Fully redundant and hot-swappable PSUs • 100% modular chassis OSA 3350 SePRC: the ideal backup to GNSS SNMPv3 (secured) Ensemble Controller with Ensemble Sync Director Ease of integration into third-party NMS OSA 3350 3RU in 19” racks
  9. 9. 9 Super optical cesium frequency performance Stability of frequency outputs outperforming ITU-T G.811.1 TDEV ePRC vs. OSA ePRC+ vs. OSA SePRC G.811.1 MTIE ePRC vs. OSA ePRC+ vs. OSA SePRC
  10. 10. 10 Holdover comparisons: G.8272.1ePRC vs. OSA ePRTC+ vs. OSA SePRTC Super optical cesium holdover performance OSA 3350 when combined with OSA ePRTC solution Minimum values Typical values
  11. 11. 11 A major innovation in atomic cesium technology • New generation of optical cesium clocks for better stability and longer lifetime • Essential solution for backup to GPS/GNSS with mobile networks, power utilities and defense, among many others • Combines with OSA 5412/22 and 5430/40 in ePRTC applications for extended holdover featuring common management Key takeaways
