VPIphotonics announces the release of VPIlinkConfigurator Version 4.4, 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 4.4 improves the network design workflow and provides functionality that supports multi-band DWDM transmission technologies including high bit rate transceivers with advanced modulation formats, colorless directionless and contentionless (CDC) configurations along with flexgrid wavelength assignment. The new built-in functionality simplifies and accelerates the design process. With the improved capabilities provided in version 4.4, VPIlinkConfigurator continuously supports its existing and addresses new applications.
Simplified Equipment Library Management – to update system requirements parameters automatically when new network design is started or to select the required library easily when an existing network design is updated.
Design Assistant – Updated Summary Table to report broken connections along with violations of equipment limits and design constraints.
Add/Drop Equipment Configuration – Enhanced Setup Node Equipment tool to allocate add/drop equipment for several nodes or the whole network simultaneously.
Multi band DWDM signal and Flex grid – simulation engine was enhanced with respect to simulation time and memory utilization.
Nonlinear Impairments – enhanced fiber models to account for Inter Channel Stimulated Raman Scattering (ISRS), which is critical at modeling the wide band DWDM transmission line.
Equalization Mode – an improved version of WSS ROADM model to account for an Optical Channel bandwidth that can significantly differ from the symbol rate for several advanced modulation formats.
Traffic Demand Routing Algorithms – a new routing algorithm to account for the OSNR degradation due to amplifier noise. The existing routing algorithms have been significantly accelerated.
