VPIlinkConfigurator™ – New version 4.3 released!

VPIphotonics announces the release of VPIlinkConfigurator Version 4.3, a versatile software tool for optical network engineering including automatic equipment placement and configuration and a thorough system-wide performance assessment. It supports equipment configuration and detailed performance calculation of complex networks including ROADMs and true ring topologies. A powerful API enables interfacing with third-party software such as common office applications and databases in addition to custom applications.

Version 4.3 offers advances in simulation and design flow for CDC and flex-grid applications with high bit rate connectivity requests. Enhanced simulation engine, design automation and performance support also for amplifier output power test, OADM express path constraint and different modes of residual dispersion assessment. With the improved capabilities provided in version 4.3, VPIlinkConfigurator continuously supports its existing and addresses new applications.

Among the new features of version 4.3 are

  • Line Terminals – a new type of add/drop equipment to model transceiver aggregators (TPA) and to build CDC configurations through the use of Setup Node Equipment tool which automates wavelength allocation and add/drop equipment configuration.

  • Multi Port Splitter Combiner – a new equipment type to model optical equipment which is used to connect TPA to WSS ROADMs in CDC configurations including connection of several MPSCMs to one WSS ROADM.

  • Lightpath bandwidth and wavelength allocation – Enhanced Setup Node Equipment tool accounts for flex-grid and channel width which depends on modulation format. At allocating add/drop equipment the tool minimizes a spectrum utilized in a network being designed.

  • System throughput and frequency range – New parameters are displayed in Channel Assignment Summary

  • Equalization mode – enhanced power control mode in equipment types used to model WSS ROADM support for power spectral density and per slot equalization

  • Variable Noise Figure – Enhanced Raman optical amplifier model supports for Dependence of Noise Figure on Gain

  • OADM port width – new parameter of OADM controls the process of Add/Drop equipment configuration and excludes invalid OADM configuration for high bit rate channels


  • Negative margins highlighting – Enhanced visualization of system performance failure in Performance summary table


  • Design issues list – simplified navigation through equipment with constraint violations in Design Assistant


  • Feature editor – a new parameter editor simplifying definition of port specific parameters in optical equipment
