Adtran releases clock upgrade for precision timing applications
Adtran has launched its Enhanced Short-Term Unit (ESTU) precision timing module for its OSA 3300 series optical cesium clocks.
The module is designed to meet the demands of industries requiring ultra-stable short-term timing. According to the company, the module can achieve performance levels comparable to the passive hydrogen maser, which is no longer available in the Western market.
The ESTU module improves short-term frequency stability, measured through Allan Deviation, a key metric for timing accuracy. This improvement is particularly valuable for sectors such as metrology, space exploration and defense, where precise synchronization is crucial for data collection, satellite communication and measurement operations. Designed to optimize short-term frequency stability, the ESTU module is a versatile addition to Adtran’s Oscilloquartz synchronization technologies. It supports both 5MHz and 10MHz output frequencies, making it suitable for a wide range of high-precision applications, including those that previously relied on passive hydrogen masers.
