Optical timing channel
PRTC-grade timing over DWDM networks
Across all industries, synchronization networks are facing a key challenge. From broadcast to utilities to government, new levels of reliability and accuracy are needed. To achieve the robust synchronization necessary for emerging applications, such as smart grids and 5G, operators need to find a new way to mitigate GNSS’s vulnerability. Unlike other delivery mechanisms, our optical timing channel (OTC) solution uses the DWDM transport layer to carry highly precise, PRTC-grade timing from the core of the network all the way to the edge. In combination with ultra-precise boundary clocks, we’re able to deliver whole new levels of accuracy and reliability while at the same time simplifying network management and reducing cost.
Highly accurate PTP transport
Our OTC technology provides a reliable and resilient way to achieve unprecedented levels of timing precision throughout the network.
With our OTC technology, the need for unnecessary equipment is removed, empowering operators to streamline their infrastructure.
Ultimate protection against GNSS failures
Our hardware-redundant synchronization solution meets even the most stringent availability needs of critical infrastructure and business continuity.
Synchronization over optical channels
Our OTC solution combines ultra-accurate PTP packet processing and optical transport optimized for the lowest asymmetric delay. Delivered from our cesium-powered ePRTC core clocks, a dedicated bidirectional channel carries PTP traffic to access locations, and precise boundary clocks at intermediate sites assure ultra-accurate timing delivery. Closely spaced, out-of-band wavelengths tackle asymmetric delay and leave all other channels available for customer traffic. With an integrated management solution for the transport and synchronization network, our OTC solution also simplifies operational processes and reduces cost. Today’s networks with several sites may use thousands of GNSS receivers – all at risk from faults and malicious activity. Our PRTC-grade timing delivery technology removes the need for unnecessary equipment, empowering operators to streamline their infrastructure.
Our OTC technology delivers the benefits of a fully integrated synchronization overlay solution, enabling operators to protect their investment by harnessing rapid innovation cycles.
Integrated, best-in-breed technology
Our OTC technology offers a proven and fully engineered solution built on best-in-class timing and optical transport innovation. It features our Oscilloquartz scalable grandmasters with multi-band, multi-constellation GNSS receivers. With boundary clock class D accuracy, these sync devices forward PTP packets with the highest levels of precision, and equipment redundancy protects the synchronization network from any failure. What’s more, our open optical transport systems deliver PTP flows at ultra-low asymmetric delay. The combination of extremely accurate PTP packet processing and optimized optical transport creates an ultra-precise synchronization overlay that mitigates any GNSS issues. As each pre-integrated component of our OTC solution comes under the management umbrella of our comprehensive Ensemble Controller and Ensemble Sync Director, it delivers unprecedented simplicity and ease of use. And, with its graphical user interfaces, an easy access to information is provided, assuring optimal transport and synchronization network performance.
