Anritsu Adds Time Error PTP Wander Function with MT1000A
Anritsu Corporation has recently added a new time error function for PTP wander, a metrics for evaluating frequency variations as low as 10 Hz to the PTP network time synchronization error to the company’s smallest-in-class 100 Gbps Network Master Pro MT1000A.
5G networks require high real-time communications supporting anticipated new services in various industries, such as autonomous vehicles, smart factories, telemedicine, etc.
PTP wander is a key index expressing long-term time synchronization stability. Adding this improved time sync measurement to the MT1000A will play an important role in assuring 5G network quality.
Due to their advantages of ultra-high speeds, high reliability and low latency, and multiple simultaneous connections, 5G communications networks are spreading into various use scenarios
Of these, high-reliability and low-latency communications are key features for implementing various industrial use cases, such as autonomous vehicles, smart factories, telemedicine, etc.
Applications using these mission-critical technologies demand the smallest possible communications latency to facilitate equipment peer-to-peer communications at the highest speeds in almost real-time, while also requiring precision time synchronization between each equipment.
Additionally, implementing low-latency communications requires support for MEC architectures in 5G networks, and precision time synchronization is essential to achieving communications between MEC systems distributed at each site.
Implementing time synchronization uses network technologies called SyncE and PTP, and assuring high accuracy and high stability synchronization using these technologies is linked to operators’ service quality guarantees about high speeds and low latency.
Anritsu has been building instruments with built-in jitter and wander test functions to measure instabilities in networks ranging from the SDH/SONET era to modern transport networks, contributing to the development of core and metro networks.
Based on this long experience and high-level technologies, the company has now added this new time error PTP wander measurement function to MT1000A time synchronization measurements.
Measuring wander supports the quantitative evaluation of long-term synchronization stability. In addition, support for the measurement of new time-synchronization networks called PTS will help assure customers’ service quality guarantees.
Moreover, the combination with the SyncE Wander MU100011A-021 and MU100090B software options facilitates ITU-T recommended pass/fail evaluation of network-supplied Ethernet frequency accuracy.
