White Rabbit Z16
The reliable precise time fan-out for White Rabbit distribution on 1G Ethernet-based networks.
WR-Z16
Reliable & precise time fan-out solution for White Rabbit (basis for the new IEEE-1588-2019 High Accuracy Default profile) distribution on 1G Ethernet-based networks.The WR-Z16 is a standalone device with 16 SFP connectors which provides sub-nanosecond accuracy time over plug-and-play optical fiber links.The WR-Z16 provides very precise IEEE 1588-2008 (PTP) in all its optical interfaces and supports NTP interoperability. Picosecond-level frequency distribution is available through a fully digital clock.The WR-Z16 incorporates failover mechanisms which combine multi-source redundancy and holdover capabilities to ensure continuous operation.
