CHARACTERIZATION OF INTER-CHANNEL CROSSTALK IN AN OPTICAL NETWORK - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18024599 Titled 'CHARACTERIZATION OF INTER-CHANNEL CROSSTALK IN AN OPTICAL NETWORK'
Simplified Explanation
This abstract describes a system for monitoring the quality of an optical communications network. The system analyzes the data channels in the network by obtaining time-domain waveforms and applying Fourier transforms to generate frequency-domain waveforms. By calculating the noise-to-signal ratio based on these waveforms, the system can estimate the optical signal to noise ratio (OSNR) penalty. If the OSNR penalty exceeds a certain threshold, a notification is generated to alert the user.
Original Abstract Submitted
An optical communications network comprises optical data links comprising data channels. A time-domain sampled waveform of a selected data channel is obtained. The Fourier transform is applied to the time-domain sampled waveform of the selected data channel to generate a frequency-domain waveform of the selected data channel. Time-domain sampled waveforms of the selected data channels neighboring data channels are obtained. The Fourier transform is applied to the time-domain sampled waveforms of the neighboring data channels to generate frequency-domain waveforms of the neighboring data channels. The noise-to-signal ratio is calculated based on the frequency-domain waveforms. Based on the calculated noise-to-signal ratio, an optical signal to noise ratio (OSNR) penalty is estimated. A notification is generated when the OSNR penalty exceeds a predetermined threshold.
