Services

Best-in-class software tools, equipment, and technologies are used during the design, development, and verification/validation phases of producing Winchester products. Parts are first designed in a 3D CAD environment and then simulated to obtain an optimum electrical performance given a specific set of parameters and requirements, based on the application. Finally, the simulation results are correlated and validated to actual measurements, reducing repeated design iterations and redundant prototypes.

Simulation

It is understood customers will likely need some kind of modeling and simulation analysis. Winchester’s simulation capabilities encompass multiple domains and types of analysis in order to provide a comprehensive, integrated design solution. Experienced engineers will build, model and analyze models that illustrate the fiber optic and signal integrity effects of the application, and provide a final solution that meets design requirements.
