# Use Cases

High Accuracy Timing for Exchanges

Problem We Solve

Improve accuracy and precision to and within their matching networks, provide better transparency to exchange participants, high resolution timestamping for network latency monitoring and the ability to monetize time distribution as a service to market participants.

Why it is Important

Increased accuracy and precision for internal timestamping using cards or switches

Time synchronization resilience with automatic failover between GNSSGlobal navigation satellite system (GNSS): A general term describing any satellite constellation that provides positioning, navigation, and timing (PNT) services on a global or regional basis.

Simplification of existing PTPPrecision Time Protocol is a protocol used to synchronize clocks throughout a computer network. On a LAN network, PTP can enable the clocks on each server to be synchronized within a sub-microsecond range, thus making it suitable for demanding applications that require precise timing and control. PTP is standardized within IEEE-1588v2. network designs with improved accuracy
Removal of PPS coaxial cabling within timing infrastructure
The infrastructure to generate revenue driven time-based services such as data capture files or timing feeds to market participants

How We Solve it

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 NTPNTP, or Network Time Protocol, is a widely used networking protocol that enables computers and devices to synchronize their system clocks with a reference time source. It ensures accurate timekeeping in computer networks by allowing devices to obtain precise time information from NTP servers, which are typically synchronized to highly accurate atomic clocks. NTP is essential for various applications and services that rely on synchronized time, such as network security, authentication, and data logging. 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.
