SYNCRO: Fiber-based GNSS and Power-over-Fiber solution

Why precise time synchronisation is essential in the digital age?

In an increasingly digitalized world, precise time synchronisation is an invisible yet critical foundation of modern infrastructures. Whether in data centers, telecommunications networks, or financial systems, nearly all applications rely on systems operating at exactly the same time. This enables seamless interaction between all systems and is therefore essential for stable operations in global trade, in industry, and in digitally interconnected applications.

With the rapid growth of artificial intelligence, requirements are increasing further: exponentially growing data volumes, real-time applications, high bandwidth demands, and global connectivity increase complexity and latency. Even the smallest delays can have critical impacts. Precise time and synchronisation data are therefore essential to ensure consistent communication, reliable processes, and accurate coordination across systems, industries, and regions - and to fully leverage the potential of modern AI networks efficiently.

The basis for precise time data is the Global Navigation Satellite System (GNSS). The highly precise atomic time references contained therein enable synchronisation in the nanosecond range and are received, converted and transmitted via fiber directly into the data center using our SYNCRO time synchronisation solutions.

The SYNCRO portfolio is the world’s first fully copper-free time distribution link and offers three different applications for data center and telecommunications customers looking for scalable timing infrastructure solutions. One portfolio for all use cases – from simple deployments to mission-critical systems – with a focus on flexibility, scalability, reliability and precise synchronisation as the foundation of modern AI and real-time networks.

The SYNCRO product family includes the SYNCRO Max, SYNCRO Eco and SYNCRO Mini systems, which have been specifically developed to meet application requirements and to integrate into existing infrastructures. Emphasis has been placed on cost efficiency, scalability and reliability. The solution enables secure, flexible and precise time distribution – without the complexity of coaxial cabling.

Benefits from the latest Power-over-Fiber generation

Power-over-Fiber (PoF) enables the transmission of energy to power the antenna via the fiber connection and eliminates the need for a separate power supply. Power is supplied directly via the fiber, which significantly reduces installation effort. Full electrical isolation avoids risks such as overvoltage, ground loops or electromagnetic interference. Using fiber-based power supply, distances of several kilometers between the RF source and the receiving system can be bridged and antennas can be positioned spatially separated to ensure additional security and redundancy.
