OSA 5420 Series 
PTP grandmaster, NTP server, GNSS receiver 

Driven by the continuing evolution of radio access networks to support higher data rates, increased coverage and better spectrum utilization, cost-effective delivery of assured phase, frequency and time-of-day synchronization at the edge of mobile backhaul networks has become a challenge. 

Are you struggling with high packet delay variation and delay asymmetries across your mobile backhaul network? Do you have difficulties in meeting frequency and phase synchronization accuracies required by LTE-TDD and LTE-Advanced technology? Our OSA 5420 Series can help. This family of IEEE 1588v2 Precision Time Protocol (PTP) grandmaster devices optimized for deployment at the network edge ensures that cost-effective and accurate synchronization is no longer a challenge. What’s more, with its NTP server and GNSS receiver capability including multiple synchronization fan-out options, our OSA 5420 Series is also ideal for deployment in legacy synchronization architectures.
