An ADVA Optical Networking Company In/Outdoor PTP Grandmaster & GNSS Receiver For maximum benefits, small cells need tight synchronization. With our OSA 5405 SyncReach™, this is easier than ever before. It features a unique dual antenna that enables it to deliver accurate and affordable small cell synchronization even in urban canyons. A clear sky view is no longer essential for accurate and reliable GNSS-based synchronization. Our OSA 5405 can be deployed in deep urban canyons closer to where small cells are located. This avoids the archaic and expensive RF cable feeds of typical GNSS installations. Instead, the OSA 5405 uses cost-effective Ethernet cabling and offers both electrical and optical interfaces. Our OSA 5405 comes in two variants: the OSA 5405-O for outdoor installations on a wall or a pole; and the OSA 5405-I for indoor installations at windows or interior walls. Indoor- or outdoor-mounted, even at street level in deep urban canyons, our OSA 5405 offers unprecedented flexibility. And, with its dual GNSS receivers and PTP grandmaster, it delivers the accurate timing that small cells require. Your Benefits O Optimum Design for Small Cells Compact, cost-effective design for indoor and outdoor applications close to small cells O No Clear Sky View Needed Unique solution that uses the reflected (multipath) signal to achieve excellent synchronization performance even at street level O Unique Indoor Dual GNSS Antenna Built-in dual GNSS receivers and antennas enabling PRTC and IEEE 1588v2 grandmaster O Simple Installation and Maintenance Powered over Ethernet. No need for RF cables and no need to correct for cable delays O Compact and Green Design Distribution of accurate timing with the smallest size and power footprint on the market O Operational Simplicity with Assurance Powered by our Syncjack™ technology, the system offers comprehensive monitoring and service assurance
