In spy war dramas, there are often scenes where, before each important operation, team members synchronize their watches to ensure unified action; in daily life, when the news broadcast music plays, everyone knows it's 7 PM Beijing time; at work, simply connecting the computer to the network automatically corrects the time... These are all simple applications of time synchronization. For our daily work and life, millisecond-level time synchronization accuracy is sufficient.

However, in many professional fields, with the continuous expansion of network clusters and communication equipment, the increasing number of network nodes and subsystem devices, and frequent interaction between master and slave devices, millisecond-level time synchronization accuracy is far from enough. For example, In wireless communication systems, the time synchronization error between terminal devices and base stations is required to be less than 3 microseconds, otherwise communication interruption may occur. In cutting-edge measurement and control, and navigation fields, the requirement for time synchronization accuracy has reached nanosecond level.
 

Relying on its profound technical accumulation in the field of time and frequency control and precise grasp of industry needs, Far East Communications has independently developed and launched a nanosecond-level time synchronization system. The system adopts a dual-mode BeiDou/GPS satellite timekeeping method, with multiple timekeeping methods such as B-code, NTP, and PTP, and can provide standard time signals with synchronization accuracy within 10 nanoseconds. At the same time, the system is equipped with a high-stability rubidium atomic clock and an ultra-low noise constant temperature crystal oscillator, and the output frequency accuracy and stability can reach 1e ^-13 level, with a self-developed high-retention intelligent algorithm, it can still maintain ultra-high time accuracy within 300 nanoseconds within 24 hours after the satellite timekeeping signal is lost.

In addition, Far East Communications has launched a number of clock synchronization systems and application devices in recent years, including integrated time synchronization equipment, phase-locked frequency standard equipment, time-frequency distributors, time-frequency optical transceivers, and bidirectional time-frequency transmission equipment, etc. It can be widely used in mobile operators, power, broadcasting, rail transit, smart hospitals, finance, civil aviation, smart cities, and other fields, providing users with stable and accurate time synchronization services.
 

Excellence comes from persistence, expertise comes from specialization. Far East Communications will continue to adhere to the innovation-driven strategy, continuously strengthen core technology research and development, and improve the full-range business layout from communication components and complete machines to industry solutions, providing better and more efficient products and services to help customers succeed in the digital age!
