On May 17, World Telecommunication and Information Society Day, XGTime officially unveiledSyncOne, China’s first 1G~800G full-rate time and frequency synchronization analysis system. Inheriting XGTime’s over 20 years of technical accumulation in high-precision time and frequency testing, this product serves as a domestically developed high-end solution tailored for synchronization performance testing of high-speed Ethernet, precisely meeting the stringent time and frequency synchronization requirements of enhanced 5G, O-RAN and computing data centers.

Centering on core test scenarios includingtime and frequency synchronization, time accuracy and nationwide timing consistency, SyncOne is dedicated to resolving synchronization performance challenges of 400G/800G high-speed Ethernet interfaces. It fully supports users in synchronous design, R&D verification, standard certification and live network operation & maintenance of current and future high-speed communication equipment and computing networks, comprehensively covering existing and prospective time and frequency synchronization test requirements.

Adhering toindependent R&Dand domestic substitution strategy, the SyncOne time and frequency synchronization analysis system adopts an innovative technical architecture and achieves multiple key technological breakthroughs:

• Full-rate and Full-interface Compatibility: It is the first domestic solution to support full-form factor interfaces including SFP-DD, QSFP-DD and OSFP, covering full-rate scenarios from 1G to 800G (GE, 10GE, 25GE, 40GE, 50GE, 100GE, 200GE, 400GE, 800GE). It is compatible with both NRZ and PAM4 encoding schemes, adapting to the technical evolution of multi-rate interfaces.
• Industry-Leading Test Accuracy: The maximum PTP measurement accuracy reaches 1ns with a time test resolution of 10ps. It complies with ITU-T G.8273.2 Class D ultra-high precision testing across GE to 800G full rate, and fully supports time and frequency synchronization performance testing in accordance with international standards including G.8262, G.8262.1 and G.8273.2.
• Dual-protocol Full-rate Support: It supports full-rate testing of both PTP and NTP protocols, enabling one-stop synchronization testing for multiple scenarios such as data centers and carrier networks.
• Customization for Carrier Centralized Procurement: Optimized specifically for centralized procurement testing of domestic telecom carriers, it fully complies with network access certification and bidding specifications, substantially improving test efficiency. 

As China’s first dedicated 800G full-rate high-precision time and frequency synchronization test system, XGTime SyncOne breaks overseas technical barriers through full-stack independent innovation and fills the domestic gap in high-speed time and frequency synchronization testing. It facilitates the transformation of China’s communication industry fromequipment independencetotesting independence, and builds a solid security foundation for time and frequency synchronization testing of computing networks, 5G-A and next-generation communication networks.

This new product launch marks another milestone for XGTime in the field of time and frequency synchronization testing. Going forward, XGTime will continue to deepen its layout in high-precision time and frequency synchronization testing, empowering domestic high-end time and frequency test instruments to enter the global leading echelon with self-developed core technological strength.
