# Digital Equalization of Ultrafast Data Using Real-time Burst Sampling

## TL;DR

This paper demonstrates digital equalization of ultrafast 40Gbps data using real-time burst sampling with a photonic time-stretch ADC, evaluating feed-forward and decision feedback equalizers.

## Contribution

Introduces a novel application of real-time burst sampling with photonic time-stretch ADC for ultrafast data equalization, including evaluation of different equalizer types.

## Key findings

- Successful digital equalization at 40Gbps data rate.
- Effective performance of both feed-forward and decision feedback equalizers.
- Validation of real-time burst sampling technique for high-speed data processing.

## Abstract

We demonstrate digital equalization of 40Gbps data enabled by use of Real-time Burst Sampling (RBS) with photonic time-stretch A/D converter. Evaluation of a feed-forward equalizer and a decision feedback equalizer is also shown.
