Thunderbolt GM330 PTP Grandmaster Clock

The Thunderbolt GM330 from Protempis, is an innovative Precision Time & Synchronisation Server designed specifically to meet the demands of Private 5G Wireless, Small Cell, O-RAN networks, industrial networks, and other emerging sectors. The GM330 provides continuous availability of UTC traceable time for phase synchronization, a critical need for LTE Advanced/5G networks and services. The GM330 can be used in either indoor or outdoor deployments that require an extended industrial operating temperature range. It includes versatile I/O options, Power-Over-Ethernet+ (POE+) capability and a compact form factor to address a variety of time & sync use cases.

Small Cells

In addition to its rugged design, the GM330 addresses the tight timing requirements of typical small cell private wireless services. As more radios and small cells are deployed to ensure coverage, the GM330 offers a scalable solution with its client count that seamlessly addresses the growing network’s time and sync needs.

4G LTE-A & 5G Services

The GM330 is a cost-effective solution for any network that requires stringent phase synchronization of 4G LTE-A/5G services. With its high reliability and purpose-built design, it easily deploys at the edge and/or network aggregation layer.

Private 5G & Industrial Data Networks

Third-party providers and municipalities are building their own private 5G networks instead of relying on WI-FI to achieve superior range and coverage. The GM330, with proven time and sync technologies, enables these organizations to meet key connectivity requirements, while its integration of functions reduces implementation cost.

Protempis has fine-tuned the GM330 to deliver precise frequency and phase synchronization signals, supporting IEEE 1588 Precision Time Protocol (PTP), Network Time Protocol (NTP), and Synchronous Ethernet (SyncE) simultaneously. The GM330 can support a range of 128 to 4000+ concurrent PTP clients (depending on the PTP profile) and handle 5,000 NTP transactions per second. There is support for a broad range of PTP profiles, allowing the GM330 to be used in a variety of applications and deployments.
