OSA 5585B PRS Cesium Primary Reference Source OVERVIEW Telecommunication networks require highly accurate clocks for the effective transmission of digital signals. One of the primary objectives of telecommunication networks is to guarantee, at the connection between different networks, a slip rate of less than one slip in 72 days. Meeting these stringent specifications requires the implementation of a Primary Reference Clock (PRC) that must generate signals with an accuracy better than 1E-11, at all times. Generally, this is achieved using Cesium clock technology, often combined with GPS receivers as backup sources. Unlike off-air receivers, Cesium clocks are autonomous, self-contained primary references immune from external influences.
