Atomic Clocks
Society has become dependent on atomic time. Atomic clocks underpin our financial transactions, communications services and broadcast services, but they are expensive to produce and maintain.Quantum technology brings a new generation of clocks which are smaller, more accurate and cost effective, and as a result this is driving an evolution of new time-critical products and services.

Clock Synchronization
Analog Devices Clock synchronizers are designed for wired networking applications, providing the clock redundancy functionality needed to maximize system uptime. Our technology supports clock synchronization with common standards, including 1 pulse per second (PPS) output signal from a GPS receiver. GPS signals are broadly available and utilize an extremely stable atomic clock as its time base, but they are often noisy. Systems rely on the IEEE1588 timing protocol to establish synchronous communications across the wired network, including synchronous Ethernet and synchronous digital hierarchy (SDH) to optical transport network (OTN) mapping/demapping. The IEEE1588 protocol has emerged as the preferred method for Clock synchronizing systems throughout both computer networks and local area networks (LAN).

Timing And Sync
Precision timing is critical for defense and commercial industries and powering essential network operations. Safran offers secure time servers and solutions for accurate network synchronization, ensuring security, compliance, and adherence to best practices. Safran excels in delivering precision timing solutions, including NTPNTP, or Network Time Protocol, is a widely used networking protocol that enables computers and devices to synchronize their system clocks with a reference time source. It ensures accurate timekeeping in computer networks by allowing devices to obtain precise time information from NTP servers, which are typically synchronized to highly accurate atomic clocks. NTP is essential for various applications and services that rely on synchronized time, such as network security, authentication, and data logging. time server appliances and GPSGlobal Positioning System is a navigation satellite system.
