OSA 5422 combines sync delivery over IPv6, 10Gbit/s high-bandwidth interfaces, support of ITU-T G.8275.2, highly-accurate multi-band GNSS receivers and extended modularity. These new capabilities mean that it can now be used across an even wider range of industries to deliver robust, secure and packet-based IEEE 1588 PTP as well as NTP synchronization. No technology offers more to help operators and enterprise organizations leverage their deployed infrastructure. Features Leading edge GNSS receiver High-availability Unique flexibility Syncjack technology Extended holdover performance Operational simplicity Details edgeSync+ | OSA 5422 Compact PTP grandmaster, NTP server, SB/MB-GNSS receiver, multi-interfacesReliable and accurate delivery of synchronization is essential to meet the stringent requirements of mission-critical applications in multiple market areas such as mobile backhaul, power utilities and broadcasting. Network operators need a robust, scalable solution to provide assured phase, frequency and time-of-day synchronization. However, achieving this in a cost-effective way is a challenge. Our OSA 5422 is a versatile and accurate synchronization device that can meet the stringent frequency and phase synchronization demands of new applications, such as 5G, while supporting legacy networks using IRIG, BITS or NTP. With a compact and flexible design optimized for deployment at the network edge, it ensures that cost-effective and accurate synchronization is no longer a challenge. Our OSA 5422 offers unique flexibility. It can be used as an IEEE 1588v2 PTP grandmaster clock. With its NTP server and GNSS receiver capabilities including multiple synchronization fan-out options, our OSA 5422 is also ideal for deployment in legacy synchronization architectures. To meet all installation demands, two ordering options are available: one with all connectors at the front and one with connectors at the rear side and a display at the front. All these features make our OSA 5422 ideal for the delivery of accurate and reliable synchronization for new and legacy solutions at the network edge.Highlights:Enables ePRTC/PRTC-A/-B and grandmaster clock functionality for frequency, phase and time-of-day delivery using multiple constellations and multiband GNSS receiver optionsAutomatic clock selection, self-calibrating delay asymmetry compensation, power supply redundancy and DoS protectionCan be used as PTP grandmaster clock, APTS, boundary clock and slave clock as well as NTP server and SSU/TSGBuilt-in synchronization accuracy monitoring and assurance functionalityHigh-end quartz and rubidium oscillator optionsEnsemble Controller, including Ensemble Sync Director, for superior management and synchronization monitoring capabilitiesApplications:Synchronization and time-as-a-service applications with the highest availabilityTiming distribution at the edge of mobile backhaul and fronthaul networks for frequency and phase synchronizationCable networks (DOCSIS 3.1) synchronizationSynchronization delivery within buildings for indoor small cell radio base stationsSynchronization of legacy network architectures based on NTP and SSUTime as a service into data center, financial, health and media networksModernized power utility networksModernized digital broadcasting studios
