Proprietary content of subsystems can be encrypted and password-protected, such that password protected simulations of proprietary models can be executed by end users, while the underlying schematics are locked from view. FTTx applications are rapidly evolving encompassing a variety of PON approaches sometimes combined with video overlay. Configuration VPIphotonics’ solutions allow optical system manufacturers to assess trade-offs between various design p g parameters, and component p manufacturers to deliver price decreases even as developments become more complex and tolerances grow tighter. VPIphotonics simulations can import data from component characterizations and systems y measurements. Results can be stored on the remote computer, or provided directly in proper order to the local GUI for data analysis and postprocessing. VPIcomponentMaker models carrier dynamics and nonlinear effects such as spectral hole burning, carrier heating, and four wave mixing.
