MUNICH--(BUSINESS WIRE)--Apr 27, 2021-- ADVA (FSE: ADV) today launched its OSA 5405-MB, the industryâs first ultra-compact outdoor PTP grandmaster clock with multi-band GNSS receiver and integrated antenna. Part of the OSA 5405 Series of smart synchronization devices for indoor or outdoor deployment, the OSA 5405-MB ensures timing accuracy by eliminating the impact of ionospheric delay variation. This empowers communication service providers (CSPs) and enterprises to deliver the nanosecond precision needed for 5G fronthaul and other emerging time-sensitive applications. The multi-band GNSS receiver and integrated antenna enable the OSA 5405-MB to meet PRTC-B accuracy requirements (+/-40nsec) even in challenging conditions. For the first time, the technology is available in an edge timing device with minimal footprint, helping operators achieve unprecedented accuracy and reliability as they roll out wide-spread small cell networks.
