OSA 3230B Cesium Primary Reference Clock Source Product Overview The OSA 3230B is an autonomous and self-contained Cesium Primary Reference Clock Source based on a Cesium beam tube, which is specifically designed and manufactured to serve network applications where an extremely accurate and stable frequency reference signal is required. Based on the latest technology, the compactly designed OSA 3230B generates a superior and highly reliable ITU-T G.811/Stratum I synchronization signal for advanced applications in telecommunication networks. clock signal complying with ITU-T G.811/Stratum 1 performance is needed over a long period of time. Ideal for Telecom Applications Standards Compliance Next-generation telecommunication networks such as radio access networks for mobile communication require precise synchronization for active interference management, effective transmission of voice, video and data services and must guarantee a superior user experience. Also legacy networks depend on an accurate frequency signal to minimize pointer adjustments originating from frequency misalignment in the SONET/ SDH payload. Meeting the increasingly stringent synchronization requirements of future applications requires the implementation of a Primary Reference Clock Source at central network office locations that generates ITU-T G.811/Stratum 1 frequency signals with accuracy greater than ±1 x 10-11 at all times. The OSA 3230B provides a frequency source with accuracy better than ±1 x 10-12 during its entire lifetime and is ideal for enhancing overall network performance and preventing up-stream network clock errors from propagating across the entire network. The OSA 3230B is designed according to all relevant industry standards including ITU-T, ETSI, ANSI, Telcordia, NEBS and CE. Its 10-year long-life Cesium beam tube enables frequency accuracy exceeding those specified by ITU-T G.811 over its entire lifetime. Operational Simplicity The OSA 3230B Cesium Primary Reference Clock Source offers a unique set of operational features and performance metrics, including enhanced and easy integration into industrial, professional time and frequency host systems. With its long-life Cesium beam tube and its extremely flexible output type capacity, the OSA 3230B is the most flexible and compact Primary Reference Clock Source available on the market, meeting the most stringent requirements where any type of Features & Benets • Performance exceeding ITU-T G.811/ Stratum 1 PRC • 10-year long-life cesium tube • Accuracy better than ±1 x 10-12 during entire lifetime • Extremely compact size • Optional signal expansion providing five additional outputs • Redundant DC power supply input or mixed AC/DC power supply • Control and monitoring via alarm contacts and RS232 communication • TCP/IP remote management port for TL1 and/or SNMP management
