Architecting the Network for the Terabit Era and in the Shadow of Shannon

Event Details

Even as we inch asymptotically ever closer to the Shannon Limit or upper bounds on spectral efficiency, the terabit era is upon us with a new generation of embedded and pluggable optical engines. In parallel, next-generation optical line systems are enabling more flexibility and capacity and, in the process, creating new deployment options and tradeoffs for operators. Join us as we discuss the future of optical networks and where we go next.

F5G Intelligent and Green Networks Towards 2030

Event Details

Session Description:

In 2020, the European Telecommunications Standards Institute (ETSI) officially started the standardization of the 5th-Generation Fixed Network (F5G) with the vision of fiber-to-everywhere. In 2022, ETSI released the F5G-Advanced white paper to describe new requirements in home, business, and industrial scenarios and the future evolution of the fixed telecommunications network. Two categories of key applications or industry trends are identified as key drivers for F5G-Advanced. One is oriented towards services and applications: ultra-high-definition immersive experience services, enterprise and industry digitalization and cloudification, 4K/8K and Metaverse. The other is directed towards network transformation: Intelligent networks with smart transceivers, ubiquitous fiber infrastructure, and Green technologies. This Session aims to bring together experts at OFC 2024 to inform and discuss F5G Intelligent and Green Networks towards 2030.

CISCO: Who Controls the DCO’s in Routers?

Event Details

Session Description:

The industry has made significant progress on the interfaces between routers, the coherent pluggable optics (DCOs), and the open optical line systems (OLS) that interconnect them – with a goal of achieving full interoperability between any DCO plugged into any router over any OLS. 

The next challenge for wide-scale deployment is how to manage it all. Specifically: should the optical controller of the OLS manage the DCO optics, or should it be managed by the router controller, in coordination with the OLS controller via a hierarchical controller (HCO)? 

In this panel, we will bring vendors and service providers together to understand the pros and cons of the different approaches and discuss how to standardize them.​

   Is Ultra-High Order QAM Necessary for Delta-Sigma Modulator in Mobile Front-Haul?

   Presenter: YIN-HE JIAN, National Yang Ming Chiao Tung University, Taiwan

    Presentation Details   Paper

   In Person

   We propose a delta-sigma-modulator (DSM) using multi-stage-noise-shaping (MASH) structure. Record high efficiencies of 1.016 (hard-decision forward-error-correction, FEC) and 1.166 (soft-decision-FEC) are achieved in the proposed MASH-DSM without the need of ultra-high-order quadrature-amplitude-modulation (QAM).Authors: YIN-HE JIAN, National Yang Ming Chiao Tung University / Jian-Wen Chen, National Yang Ming Chiao Tung University / Chih-Chun Wang, National Yang Ming Chiao Tung University / Tzu-Chieh Wei, National Yang Ming Chiao Tung University / Chi-Wai Chow, National Yang Ming Chiao Tung University / Chien-Hung Yeh, Feng Chia University

   We experimentally demonstrate a 1.92-Tb/s CPRI-equivalent data-rate supporting 1024-QAM OFDM signal in a direct-detection-based digital-analog radio-over-fiber mobile-fronthaul link using ANN for signal pre-equalizations. Performances of pre-equalizers or post-equalizers based on different methods are also studied.Authors: Junhao Zhao, Fudan University / An Yan, Fudan University / Guoqiang Li, Fudan University / Zhongya Li, Fudan University / Wangwei Shen, Fudan University / Yongzhu Hu, Fudan University / Nan Chi, Fudan University / Junwen Zhang, Fudan University

   Sigma-delta modulation can encapsulate an analog radio signal in a digital bit stream enabling low-cost synchronous radio-over-fiber links. This paper covers both direct modulated links and links with external upconversion for use in fronthaul connections.Authors: Guy Torfs, Ghent University - imec / Achim Vandierendonck, Ghent University - imec / Fatemeh Zardosht, Ghent University - imec / Caro Meysmans, Ghent University - imec / Xin Wang, Ghent University - imec / Haolin Li, iCana / Piet Demeester, Ghent University - imec
