• 100GbE, Multilevel Modulation Formats and Coherent Detection
  VPIsystems experts will discuss design aspects of 100Gb/s transmission systems. This includes options for generating multilevel modulation formats such as mPSK, mQAM, and OFDM, pro's and contra's for using direct and coherent detection, as well as requirements on optical and electrical components.

• Tunable Lasers and Photonic Integrated Circuits
  Photonic Integrated Circuits technologies (PICs) are the focus of new component design. PICs feature a large variety of complex multifunctional elements as integrated laser-modulator, I-Q modulator/receiver or multi-section tunable laser. VPIsystems experts will demonstrate design applications for novel tunable lasers and photonic integrated circuits devices. Designs include the modeling of carrier dynamics, nonlinear effects or tuning dynamics, among other.

• Electronic Digital Signal Processing and Equalization
  Requirements for robust and cost-effective WDM networks drive the demand for electronic pre-compensation and equalization (e.g., FFE-DFE, MLSE, coherent detection associated to DSP). VPIsystems experts will demonstrate performance advantages of different techniques in light of impairments resulting from transmitter/receiver influences, fiber propagation, optical bandwidth and noise limitations.

• Dynamic Network Reconfiguration and EDFA Transients
  VPIsystems experts will illustrate the impact of dynamic traffic changes on system performance from adding/dropping and switching channels using the new 'transient simulation environment' available in the latest VPItransmissionMaker release. Different control schemes for EDFA transients will be discussed. The impact of power loops in Ring architectures will be illustrated.

• Aggregation, Optical Access and RF-over-Fiber
  Requirements for the delivery of analog and digital services in access networks including FTTx/PON and wireless backhaul will be discussed. Predicting network performance requires modeling impairments resulting from QAM distortion ingress, SBS and others. Various examples of access topologies and high dynamic range systems will be shown, for instance the usage of reflective semiconductor optical amplifiers (RSOA) in PON-ONUs.

• Raman Amplification and Doped-Fiber Applications
  An introduction into the theoretical background of modeling Er/Yb doped or co-doped fibers for amplification and lasing will be explored. Examples of designs for Er/Yb co-doped fiber amplifiers, cladding pumped high power lasers and Er doped pulsed fiber lasers will be presented. Automated Raman pump optimization in light of realistic fiber propagation characteristics will be discussed.

• Equipment Configuration for Branched Networks
  The configuration of optical transmission links requires consideration of many trade-offs to optimize performance while minimizing costs. The presentation shows how to capture innovations as link design rules and equipment libraries to help application engineers respond to RFQs by configuring equipment based on brown and green field requirements. Detailed customizable reports (such as system performance, BOM, equipment utilization) will be generated.

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.

Learn more about VPI's current R&D activities! VPIphotonics partners with public research institutes, industry and universities to develop advanced solutions for the design and optimization of future photonic networks. These activities range from components design to network planning.

The purpose of the VPI-100 project is to develop new modeling functions enabling the analysis, design and optimization of next generation transmission systems with data rates of 100Gbit/s and beyond. VPIsystems experts will discuss modeling constraints and development plans related to this project. VPI-100 is part of the Celtic initiative 100-GET (100 Gigabit Ethernet Transport Technologies).

VPIphotonics partners with Acreo, HHI and u2t to develop realistic models for high-speed electrical and opto-electrical components based on both analytical models and laboratory measurements.

VPIphotonics collaborates with atesio, ZIB and HHI to develop new methods and tools for the design, optimization and deployment of FTTx networks targeting current (GPON, GEPON, 10GEPON) and future (WDM PON, OCDMA) optical access technologies.

VPIlinkConfigurator is a versatile software tool for optical link engineering including automatic equipment placement and configuration and a thorough system wide performance assessment. This tool enables the rapid turnaround of network design tasks, product application requests and RFQs. In addition, uniform results, across an organization, are ensured through the use of controlled equipment libraries and link design methodologies.

Version 3.1 provides powerful link modeling capabilities using sophisticated, patented algorithms in conjunction with an easy-to-use graphical user interface. It supports equipment configuration of complex network topologies containing nodes that serve as traffic branching and re-entry points. Interconnected links are shown in a two-dimensional topology display which allows visualizing details of nodes, repeater huts and fiber routes. The product's powerful link modeling capabilities ensure that designs comply with all physical layer design rules and are cost optimal, taking into account available equipment choices. Monitor points placed along the link help to extract information on goals and actual performance in either graphical or numeric format. Bill of Materials and performance reports are automatically created in a customizable format. A powerful API allows for virtually complete control of the link design process and performance assessment using familiar programming tools and integration with other applications including, for example Excel and MS Access.

VPIsystems is pleased to present Version 8.3 of its market-leading Photonic Design Automation suite VPItransmissionMaker & VPIcomponentMaker providing many new modeling features, improved usability and advances in design process and data analysis compared to the previous version.

Version 8.3 offers enhanced capabilities for signal synchronization and BER estimation of systems with multilevel modulation formats, or operating in burst mode. To address the latest research and development interests, significant modeling advances for fiber gratings, EAMs, PMD emulators, and components with nonlinear transfer characteristics are also provided. Among the advances in the product's usability are the new Search and Quick Find functionalities that allow you to locate easily modules and designs in standard and user-defined libraries. VPItransmissionMaker Optical Systems has been enhanced to support the simulation of power dynamics in EDFA-based fiber networks, including the study of mesh networks with complex topology.

VPIsystems supports 140+ universities and non-profit research centers around the world to simulate lab experiments, perform classroom demonstrations, and investigate new designs. The VPIsystems University Program offers academic software licensing and training discounts, flexible licensing options and course material development.
