Product Description:
Reliable and accurate synchronization is crucial for meeting the strict requirements of critical applications in various market domains such as mobile backhaul, power utilities, and broadcast media. Network operators require a robust, scalable, and upgradable solution to provide guaranteed phase, frequency, and time synchronization. However, achieving this goal in a cost-effective manner is a challenge.
Most critical applications rely on high-precision phase, frequency, and time synchronization. Our T812 eliminates the challenges of cost-effectiveness, accuracy, and reliable synchronization for next-generation technologies.
This IEEE1588v2 Precision Time Protocol (PTP) master clock device supports 10Gbit/s and 1Gbit/s interfaces with hardware timestamping, optimized for deployment in network edge conditions. Additionally, with its NTP server and GNSS receiver functionalities, our T812 is also well-suited for deployment in traditional synchronization architectures.
The T812 ensures reliable and precise synchronization that meets the most stringent requirements. To accommodate all installation needs, we offer two ordering options: one with all connectors on the front and another with connectors on the back.
