Flexible Filter Bank Multi-Carriers PON Based on Two-Dimensional Multiple Probabilistic Shaping Distribution

Abstract

We propose a filter bank multi-carriers (FBMC) passive optical network (PON) system based on 2-D multiple probabilistic shaping (MPS) distribution to achieve flexible and adjustable access bit-rates. The proposed PON can assign different probabilistic shaping schemes to different time-slots and subcarriers, thus improving the system flexibility and adjustability in both the time and frequency domains. Carrier-less amplitude and phase modulation are adopted to achieve the implementation of the intensity-modulation and direct-modulation applied in our proposed PON system. Moreover, for the first time, an experiment demonstrating MPS FBMC signal transmission over a 25-km standard single mode fiber in PON system is successfully carried out to verify the favorable performance. The bit error rate performance of different MPS time-slots at bit-rates of 23.665, 20.663, 17.666, and 15.481 Gbit/s are investigated. The received optical powers at the threshold for hard-decision forward error correction are −16.13, −16.94, −17.85, and −18.81 dBm, respectively. These experiment results indicate that our proposed MPS FBMC PON system can be flexible and adjustable in acquiring different and dynamic access bit-rates, which suggests a prospective solution for the next generation passive optical network.

“…Mobile communication has undergone tremendous change from the First Generation (1G) that offered mobile voice calling services that was launched in the year 1980 and services offered by it was analog in nature. Since then, after every 10 years a new generation of the mobile communication has been introduced in the market [1]. The Second Generation (2G) digital cellular services launched in 1990 as Global System for Mobile Communication (GSM) commercially achieved a great success in the market.…”
