Oscilloquartz optical pumping cesium clocks put atoms into the correct state far more efficiently than legacy magnetic cesium solutions. The resulting improved accuracy and up to ten times greater clock stability exceeds the current ITU-T G.811.1 enhanced primary reference clock (ePRC) specification. What’s more, when combined with our core grandmaster devices to create an enhanced primary reference time clock (ePRTC), our most capable optical cesium solutions provide 100 nanoseconds of holdover for up to 55 days.
With twice the lifespan of legacy magnetic cesium solutions and the ability to measure 100 times more atoms, Adtran’s highly efficient optical pumping cesium clock is fast becoming an indispensable element of timing and synchronization networks worldwide. Our all-digital, fully RoHS-compliant devices provide unrivaled precision for any mission-critical application and remain functional over extended periods, lowering the cost of network synchronization and rendering timing networks more sustainable and secure.
Building on the long-term stability of our optical cesium atomic clocks, our Enhanced Short-Term Unit (ESTU) precision timing module sets a new standard for short-term frequency stability. Available as an enhancement to our OSA 3300 HP and SHP, the ESTU module significantly reduces Allan Deviation to deliver unprecedented accuracy for industries such as aerospace, metrology and defense. Supporting both 5MHz and 10MHz outputs, it provides synchronization levels comparable to a passive hydrogen maser – now unavailable in the Western market – ensuring ultra-precise timing for high-stakes applications like satellite communications and deep-space exploration.
