coreSync™ | OSA 5440

Modular, redundant, high-capacity PTP grandmaster, SB/MB-GNSS receiver, SSU+

Reliable and accurate delivery of synchronization from the core to the network edge is essential to meet
the stringent requirements of new mobile, fixed and cable networks. However, the challenges go beyond
accuracy. As well as strict precision, network operators need a robust, scalable and cost-effective
solution that can work over packet-based networks as well as legacy infrastructure
Our OSA 5440 is a carrier-grade ePRTC, PRTC A/B, SSU and IEEE 1588v2 grandmaster clock supporting 10Gbit/s and 1Gbit/s
interfaces with hardware timestamping. Its modular design with technology-focused cards enables seamless capacity
increases and technology migrations. The OSA 5440 supports all legacy sync signals and all IP-based timing protocols.
Its NTP server, multiple types of outputs and GNSS receiver capabilities make it ideal for the smooth upgrade of legacy
synchronization architectures. And with its ability to deliver precise synchronization to DOCSIS 3.1 remote PHY devices,
the OSA 5440 is also a powerful tool to help cable operators tackle booming demand. Its modular design offers complete
flexibility and supports a pay-as-you grow model. In addition, our integrated SyncjackTM technology provides in-service
synchronization monitoring and assurance without the need for expensive test equipment. What’s more, our OSA 5440
enables advanced high-capacity, multi-technology synchronization solutions with the most compact design.
