Optimizing Bipolar Constellations for High-Rate Transmission in Short-Reach Fiber Links with Direct Detection
Abstract
Bipolar modulation increases the achievable information rate of communication links with direct-detection receivers. This paper optimizes bipolar transmission with a modulator bias offset for short-reach fiber links. A neural network equalizer with successive interference cancellation is shown to gain over 100 Gbit/s compared to standard receivers.
