Product Overview

This product provides a function to minimize a deviation of error, which results from traffic overload between GrandMaster equipment and slave module, and error during classification of network domain.

This product has interface that has both master function and slave function. As a master function, it delivers time information to slave modules, and as a slave function, it corrects the time difference by PTP coordination.

This product coordinates to more than two master equipments through dualization, which allows the product to acquire precise timing information, and synchronize it’s time to master equipment that has superior timing quality, and then transmit that timing information.

Produce precision timing synchronization

We developed our own algorithm (SPW1588TM), which allows this product to synchronize timing more accurately with master equipment, and produce reliable high precision clock synchronization.
