METHOD, APPARATUS AND SYSTEM FOR DETERMINING MULTIPATH INTERFERENCE (MPI) ON AN OPTICAL LINK - A simplified explanation of the abstract
This abstract first appeared for US patent application 17521128 titled 'METHOD, APPARATUS AND SYSTEM FOR DETERMINING MULTIPATH INTERFERENCE (MPI) ON AN OPTICAL LINK
Simplified Explanation
The patent application describes a method, apparatus, and system for determining multipath interference (MPI) in optical communications. The goal is to provide an effective and low-cost way of detecting or measuring MPI.
- The method involves inserting multiple zero-power gaps into the transmission signal in the time domain.
- Some of the zero-power gaps inserted in the main signal do not overlap with the zero-power gaps of the reflection of the main signal.
- By analyzing the power inside and outside the zero-power gaps, the strength of the MPI can be determined.
Potential Applications
- Optical communication systems
- Fiber optic networks
- Data centers
Problems Solved
- Detecting and measuring multipath interference in optical communications
- Providing a cost-effective solution for MPI detection
Benefits
- Effective and accurate detection of MPI
- Low-cost implementation
- Improved performance and reliability of optical communication systems
Original Abstract Submitted
There is provided a method, apparatus and system for determining multipath interference (MPI) in optical communications. It is object of embodiments of the present disclosure to provide an effective, low-cost way of detecting or measuring MPI. To effectively detect and measure the MPI, multiple zero-power gaps are inserted into the transmission signal (optical signal) in time domain. In some embodiments, at least some of the zero-power gaps inserted in the main signal do not overlap the zero-power gaps of the reflection of the main signal. Using the zero-power gaps contained the main signal and the reflection (where applicable), power inside and outside the zero-power gaps are determined. Then, the strength of the MPI is determined based on the determined power inside and outside the zero-power gaps.
