Full RoHS 3 Compliance

Based on the latest Cesium III technology from Microsemi our TimeCesium® 4400 is an autonomous Primary Reference Source designed for telecom network operators to generate superior and highly reliable G.811 synchronization signals for advanced network services. The TimeCesium 4400 produces accurate, spectrally pure, and stable output signals using a cesium beam tube resonator. Using a TimeCesium 4400 delivers total control of your network synchronization source, enhances network performance, reduces errors in the SONET/SDH payload, and prevents up-stream network clock errors from propagating across the network.
