The OSA 5412 and 5422 address key sychronization challenges for communication service providers, enterprises, broadcast networks and power utilities. With multi-band GNSS receivers for nanosecond accuracy and support for eight field-upgradeable 10Gbit/s ports, they bring new levels of timing accuracy and resilience to edge networks. These unique timing devices ensure the scale and efficiency needed for next-generation smart grids, industrial IoT applications and 5G connectivity.
