Introducing the OSA 5440, the ultimate tool for fixed, mobile and cable network operators looking to prepare for 5G while maximizing the value of their frequency synchronization infrastructure. The new solution delivers highly precise, phase and time-of-day synchronization with unbeatable resilience and scale. It offers full hardware redundancy, line rates up to 10Gbit/s and an unprecedented number of fan-out options. Already being leveraged by a major network service provider, our OSA 5440 is the perfect technology for smoothly migrating legacy networks to packet-based timing with no costly upgrades or interruptions to service.
