Protempis Thunderbolt PTP GM330 Grandmaster Clock
The Protempis Thunderbolt PTP GM330 is a device that provides phase, time, and frequency synchronisation across an entire infrastructure using IEEE 1588 PTP technology.
Its robust design makes the product suitable for installation in both indoor and harsh outdoor environments.
Perfect Synchronisation for Packet Networks
The Protempis Thunderbolt™ PTP GM330 Grandmaster Clock is designed for various next-generation communication and data networks, including private 4G/5G networks, O-RAN, small cells, and others requiring phase synchronisation.
Key Integrated Technologies and Connectivity:
- GNSS Time Source: The device integrates an advanced GNSS satellite signal receiver, which serves as the primary and highly accurate source of reference time.
- PTP Synchronisation: The product fully supports the PTP protocol for precise time distribution, ensuring perfect synchronisation of all network elements.
- 40 Gigabit Line-Rate Switching: The architecture features line-rate switching with a total throughput of up to 40 Gbps, guaranteeing minimal data transmission latency.
- Four 10-Gigabit Optical/Copper Ports and Two 1-Gigabit Ethernet Ports: Flexible connectivity is ensured by a combination of four 10GbE ports (supporting both fibre and copper), supplemented by two standard 1GbE Ethernet ports.
Main PTP Synchronisation Features:
- Wide Range of Supported Clients and Operating Modes: The device can serve from 128 to 4,000+ clients, depending on the selected PTP profile. It supports key modes such as Grandmaster (GM), Boundary Clock, Freerun, APTS, and SyncE.
- Support for All Major PTP Profiles: The system ensures full compatibility across various industries by supporting standards such as IEEE 1588, G.8265, G.8275.1, G.8275.2, 802.1AS, as well as specific profiles for Power, Telecom, Enterprise, and Broadcast (SMPTE).
Integrated GNSS Capabilities and Performance:
- Dual-Band Connectivity (L1 and L5) for Maximum Security: The use of two frequency bands, L1 and L5, significantly enhances overall reception stability and provides high resilience against jamming and spoofing.
- Continuous Time Availability with UTC Traceability: The device guarantees continuous access to precise time that is directly traceable to Coordinated Universal Time (UTC), which is essential for reliable phase synchronisation.
- Protempis Technology and Advanced Holdover: The system fully leverages the maximum performance of the integrated Protempis GNSS technology. During a temporary loss of satellite signal, the premium Holdover mode ensures the network remains stable and perfectly synchronised, even without an external time source.
