Adtran Expands Optical Cesium Clock Portfolio for Network Timing

ADTRAN Holdings Inc. (NASDAQ:ADTN) is one of the best small cap tech stocks with biggest upside potential. Earlier on June 2, Adtran announced the expansion of its Oscilloquartz optical cesium portfolio with the introduction of the new OSA 3200 SP and OSA 3250 ePRC atomic clocks. The additions aim to make precision timing more accessible across a range of network environments by offering lower-cost optical pumping cesium technology.

The new OSA 3200 SP and OSA 3250 ePRC models use advanced optical pumping technology, which provides several advantages over traditional magnetic cesium clocks. The benefits include improved holdover capabilities, simplified maintenance, and a typical service life of 10 years, which is 2 years longer than typical magnetic ePRC clocks. By building on the same proven platform as Adtran’s high-end cesium models (OSA 3300 and 3350), the solutions enable telecom operators, data centers, power utilities, and defense networks to modernize their synchronization infrastructure while reducing operational complexity and cost.

As the sole vendor offering optical pumping cesium solutions, Adtran is uniquely positioned to support customers facing supply chain risks and escalating performance demands. These lower-cost solutions enable more operators to benefit from the accuracy, longevity, and modern manageability required for resilient and secure critical timing infrastructure.

ADTRAN Holdings Inc. (NASDAQ:ADTN) provides networking and communications platforms, software, systems, and services in the US, Germany, the UK, and internationally.
