摘要： The present invention is an apparatus, method and system for time synchronizing data from various sensor types that enables data fusion and transport. To provide this capability, the present invention utilizes an inverted Passive Optical Network (PON) approach for synchronous communication. Further, the present invention introduces an inverted Passive Electrical Network (iPEN) that extends the iPON approach. Data that are in a common format with embedded time synchronization information can easily be integrated or fused and transported over such communication links. The present invention provides the ability to merge and aggregate data from a wide range of disparate sensors and systems while maintaining close synchronization. The present invention is appropriate for synchronization of data, voice, and video onto a single network and/or multi-tiered networks and can also handle signal processing and control technologies at line rates well into the Gigabits per second (Gbps) range.
