PTP Grandmaster Clock
As methods of data transfer evolve, so too does the need for increased speed in information transmission. Precision Time Protocol (PTP), as defined by the IEEE 1588 standard, provides the most advanced method of synchronisation over today's Ethernet networks. To support optimum network time synchronisation, Spectracom supports the latest features of Precision Time Protocol Version 2 (PTP v2) in its SecureSync PTP Grandmaster Clock system. Up to 6 PTP ports can be added, each one creating a physically isolated network, allowing for maximum scalability to handle the expansion of your network infrastructure.
Offering the most advanced combination of network timing accuracy, security, and capability available on the market, the SecureSync PTP Grandmaster Clock is the premiere network time and synchronisation solution for your mission-critical applications. Equipped with an innovative 10/100/1000 Base-T Gigabit PTP Option Module (model 1204-32), the SecureSync PTP Grandmaster Clock uses standard SFP's to connect your copper of fiber networks. It boasts industry leading throughput due its dedicated resources devotes solely to PTP operations. PTP functions are implemented in hardware and separated from all other management functions resulting in much higher performance and reliability.
The SecureSync PTP Grandmaster Clock is designed for high performance/low-latency computing applications in financial, industrial, and defence markets with an enhanced level of timing performance, so that the management of real-time events over wide areas is drastically improved. This rack-mountable and modular precise time referencec/source includes options for other precise time and frequency functions such as reading and generating IRIG timecode formats capable of delivering accuracy from microseconds to tens of nanoseconds to various devices.
Add STL to GPS or GNSS input references to improve resilience, or use STL alone for indoor applications.
To achieve the best performance, use PTP to precisely distribute time across a LAN from the SecureSync PTP Grandmaster Clock to our TimeKeeper™ LINUX PTP precision software client installed in your servers (see TimeKeeper datasheet). PTP ensures that you will get the best time transfer performance over a managed network.
