VPItransmissionMaker™ & VPIcomponentMaker™ Version 8.5
VPItransmissionMaker/VPIcomponentMaker Version 8.5 provides many new modeling features, improved usability and advances in design process and data analysis compared to the previous version.
Version 8.5 offers enhanced capabilities for BER estimation of systems with DmPSK-type modulation formats, statistically balanced generation of m-ary random symbol streams, and significant modeling advances for WDM-PONs, OFDM systems, and dynamic optical networks.
VPIcomponentMaker™Active Photonics provides new modeling advances to better support the design of Photonic Integrated Circuits (PICs), including new models for linear optical waveguides and EAM sections.
Among the usability advances of Version 8.5 are improved Search functionalities, enhanced control of multiple (possibly remote) simulation servers, and improved data visualization and analysis features of VPIphotonicsAnalyzer.
