• 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.

• 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.

• 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 ROADMs. Different control schemes for EDFA transients will be discussed. The impact of power loops in Ring architectures will be illustrated.

• 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, MSPE, CMA). 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.

• 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.

• Semiconductor based Lasers and Amplifiers
  A high degree of flexibility in adapting model characteristics and accurate numerical techniques are required to predict the complex nonlinear dynamics of multi-element active photonic circuits and lasers over wide optical bandwidths. VPIsystems experts will demonstrate design applications for integrated tunable lasers, high-power lasers, ultra-fast sources, optical switches, edge detectors, wavelength converters and regenerators.

• Link Configuration for New Systems and Upgrade Scenarios
  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 new algorithms for adaptive mitigation of coherent 16-QAM constellation distortions. We show that 16-QAM is a potential candidate for the implementation of 100 Gb/s transmission.

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 3.0 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 8.0 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.

The new VPIdesignRules control interface supports the quick assessment of signal quality measures in WDM transmission systems using given or self-written engineering design rules. Link analysis now also supports the tracking and visualization of signal properties versus propagation time, and the calculation and visualization of customized variables from the tracked signal and path characteristics. New and enhanced models for optical transmitter and receiver components used in mPSK, mQAM and OFDM transmission systems are offered, and significant modeling advances for AWGs, SOAs, polarization tracking are provided. To speed up the design process, interactive simulations (such as parameter sweeps, optimizations, Monte-Carlo variations) can be directed from a single user interface to multiple local or remote cores. Version 8.0 supports Windows 32 and 64-bit flavors.

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.

Photonics Curriculum v 4.0

With the Photonics Curriculum our partners receive a free package of course material including lecture notes and laboratory exercises for academic programs. The curriculum is designed to teach the basics of Photonics using VPIsystems modeling and analysis tools. The material consists of individual modules that are customizable and extendable. The latest version 4.0 contains 14 course modules with new laboratory exercises for VPItransmissionMaker & VPIcomponentMaker v 7.5 and higher.

Free Simulator – VPIplayer^TM

Sophisticated simulation setups can be exported from VPIphotonics optical equipment design suite, easily distributed as dynamicDataSheet™ (dds), and run in the free simulator VPIplayer. This empowers R&D engineers or teachers to present their ideas to colleagues, customers or students who have less specialized technical knowledge, and no need for detailed design and simulation software. VPIplayer comes with a fully featured photonic simulation engine and generates results on flexible data analyzers. Interactive settings allow adjusting parameter settings via predefined sliders.
