Introducing the OSA 5430, the first IEEE 1588 grandmaster clock device on the market to support PTP, NTP and SyncE over multiple 10Gbit/s Ethernet interfaces. Our OSA 5430 is designed to help network operators achieve the stringent phase and time synchronization requirements needed for LTE-TDD, LTE-A and 5G RAN networks.
