ADTRAN announced on January 29, 2025, the launch of its Enhanced Short-Term Unit (ESTU) precision timing module. This new addition is for its OSA 3300 High-Performance (HP) and OSA 3300 Super High-Performance (SHP) optical cesium clocks.
The ESTU module is designed to meet the demands of industries requiring ultra-stable short-term timing, achieving performance levels comparable to the passive hydrogen maser, which is no longer available in the Western market. It significantly improves short-term frequency stability, measured through Allan Deviation.
This enhancement provides synchronization accuracy and reliability essential for sectors including metrology, space exploration, and defense, enabling more stable data collection and satellite communication. The solutions are the first in the market to combine the short-term stability of a passive hydrogen maser with the long-term stability of a high-performance cesium clock.
