PHASED BURST MODE RECEIVER EQUALIZATION TRAINING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18125225 titled 'PHASED BURST MODE RECEIVER EQUALIZATION TRAINING

The abstract of the patent application describes a phased approach to training an upstream burst mode receiver equalizer, progressing incrementally through modulation schemes requiring increasing levels of equalization while maintaining the capability to accurately recover data.

  • The phased approach includes initial training using a simple modulation format, followed by intermediate phases of different modulation schemes, and a final training phase using the PON-defined upstream modulation format.
  • Equalizer settings generated during each phase are used as a starting point for the next phase, ensuring accurate data recovery throughout the training process.
  • The final phase updates the burst mode equalizer to match the PON-defined upstream data rate, optimizing performance for high-speed transmission.

Potential Applications: This technology can be applied in the field of optical communication systems, specifically in upstream burst mode receiver equalization for improved data transmission.

Problems Solved: This technology addresses the challenge of training upstream burst mode receiver equalizers to handle varying levels of equalization required for different modulation schemes.

Benefits: The phased approach ensures optimal performance of the equalizer across different modulation schemes, leading to improved data recovery and transmission accuracy.

Commercial Applications: This technology has commercial applications in the telecommunications industry, particularly in the development of high-speed optical communication systems for data transmission.

Questions about the technology: 1. How does the phased approach to training the equalizer improve data recovery in upstream burst mode receivers? 2. What are the key benefits of using the PON-defined upstream modulation format in the final training phase?


Original Abstract Submitted

A phased approach to training of an upstream burst mode receiver equalizer is disclosed that proceeds incrementally through modulation schemes requiring increasing levels of equalization in a manner where the equalizer maintains the capability to accurately recover data transmitted during each training phase. The phased approach includes an initial training phase (one or more upstream bursts) using a simple modulation format, one or more intermediate phases of different modulation schemes, and a final training phase using the PON-defined (high) line rate upstream modulation format. Equalizer settings generated during the initial phase are used as a starting point for the equalization process in the next training phase, and so on, until the equalizer training reaches the final phase where the ONU uses the PON-defined upstream data rate and the burst mode equalizer is updated accordingly.
