FFT-Based Digital Clock Recovery for Coherent Transmission Systems with Multilevel Modulation Formats
presented by Hadrien Louchet in Vienna, Austria on Wed, Sep 23th
Abstract:We propose a digital clock and timing recovery algorithm for coherent transmission with multilevel modulation formats and demonstrate its robustness against signal distortions due to CD, PMD, ASE- and phase noise.
14th OptoElectronics and Communications Conference (OECC)
Photonics Modeling of Components, Systems and Networks (Tutorial)
presented by André Richter in Hongkong, China on Jul 13-17th
Abstract:Realistic photonic modeling of component characteristics, system and network concepts can be used to test the performance of existing or to-be-designed optical equipment, and define requirements for new concepts to ensure robust operation for all application scenarios. As with experimental work, care must be taken when designing simulation scenarios that should represent real world problems. When interpreting simulation results, one needs to consider what aspects of reality have been represented accurately by the underlying modeling, and which ones have been ignored.
This tutorial presents methods for accurately modeling aspects of modern optical transmission systems with channel data rates of up to 100Gb/s. It will provide simulation guidelines and application demonstrations for physical modeling of photonic technologies and components, behavioral modeling of components in systems, assessment of limitations of electronic driver and receiver circuitries, system performance evaluation and optimization, parametric modeling of link characteristics, and tracking dynamic effects in networks.Impact of Transmitter Electronics for High-Speed Systems Applications
presented by André Richter in Hongkong, China on Jul 13-17th
Abstract:Key issues related to the modeling of electro-optic transmitters are discussed in this paper. These topics include limitations resulting from the transmitter frequency response and driving electronics. Simulation results illustrate the importance of realistic modeling in high-speed systems.
11th International Conference on Transparent Optical Networks (ICTON)
Important Device Limitations of Transmitter and Receiver Concepts When Designing 100G Transmission Systems (invited)
presented by Cristina Arellano in Ponta Delgada, Portugal on Tue, Jun 30th
Abstract:We discuss in this paper important aspects related to the design of electro-optic transmitters and receivers. Among others, we investigate limitations in 100G transmission systems resulting from the frequency response of devices and non-linear effects. Numerical simulations illustrate the importance of realistic modeling.
14th European Conference on Networks and Optical Communications (NOC)
A Parametric Approach to Optical Systems Design, Optimization and Validation
presented by Hadrien Louchet in Valladolid, Spain on Fri, Jun 12th
Abstract:We discuss the use of a parametric approach to track, visualize and analyze system characteristics and demonstrate how design rules can be used to validate that systems operate properly. Our approach provides a rapid design methodology as well as a method for verifying vendor's designs and network configurations. Examples of mapping different impairments are evaluated versus geographical position or various signal characteristics for different system configurations. Further on, we demonstrate how the impact of dynamic network events (such as channel switching, EDFA gain transients) can be tracked and analyzed.
