Oscilloquartz Unveils Synchronization Solution to Enable the Small Cell Era

May 2017 by Marc Jacob

Oscilloquartz, an ADVA Optical Networking company, today launched the OSA 5405 SyncReach(TM), an integrated PTP grandmaster and GNSS receiver with a patent-pending dual antenna and receiver to enable the mass roll out of small cells. The new technology has been specifically engineered to provide accurate and affordable phase synchronization for the rapidly growing small cell market and meet the stringent timing requirements of 4.5G and 5G connectivity. With the OSA 5405 operators can migrate from legacy GNSS RF antennas and cables to standard, cost-effective copper and fiber Ethernet cabling, reducing capital expenditure and operating expenses. Available in both indoor and outdoor variants, the OSA 5405 can be deployed in the most challenging environments, including urban canyons where GPS signals fail. The OSA 5405’s miniscule form factor also enables it to be positioned on indoor windows to avoid multipath signal interference from objects within the building.

The compact design and power-over-Ethernet capabilities of the indoor- or outdoor-mounted OSA 5405 enable synchronization right at the edge of the mobile network. This creates dramatic reductions in complexity and power requirements as well as lower costs for installation and operation. Another key feature of the new technology is IP connectivity. This means that synchronization becomes another element of the internet of things. The OSA 5405’s highly precise GNSS-sourced synchronization is supported by network-based Sync-E and PTP backups. In high-rise buildings it can also deliver synchronization recovered from the GNSS smart receiver over optical fiber. The ADVA FSP Network Manager with comprehensive Syncjack(TM) assurance guarantees efficient operation. What’s more, the OSA 5405 uses a unique dual GNSS antenna and receiver algorithm to mitigate interference from multipath signals that can affect accuracy, particularly in urban canyons.
