Brandywine - OSA 3250 Optical-Cesium Precision Timing
- Uses optical-pumping cesium technology rather than magnetic selection for higher stability and longevity.
- Fully compliant with ITU-T G.811 PRC / G.811.1 ePRC standards.
- Supports essential timing outputs such as BITS, PPS (1PPS), and analog frequency.
- Compact, modular design suitable for deployment in racks, enabling scalable deployment across telecom, defense, utilities, and data-center environments.
- Long service life and improved holdover performance — offering enhanced reliability even during extended GNSS disruptions.
- Remote and secure management capabilities, including support for SNMPv3 and integration with orchestration/management suites (e.g. Mosaic Controller).
The OSA 3250 delivers modern, optical-cesium precision timing — offering a compact, modular, and cost-effective solution to replace ageing magnetic cesium clocks. It provides industry-standard ePRC timing, long-term holdover stability and secure remote manageability — ideal for 5G networks, power grids, data centres or critical infrastructure.
