Whether challenged to design a multiple-position blindmate RF connector module, develop a miniature high-current power connector, or value-engineer a problematic cable assembly, the end result is always the same – Winchester’s engineering team can solve the problem and provide a cost-effective solution to help customers bring their products to market on time and within budget, maintaining their competitive edge.

Product Design and Development
Winchester Connector design is a 4 phase gate process that begins with the customers’ requirements. A concept is captured in a team environment utilizing multi-disciplined members, including Mechanical, Electrical, Quality and Manufacturing engineers. Our design team works with you to determine options and actively participates with design down select process.
After completing the down select process of your design Winchester uses the latest SolidWorks CAD and simulation tools that include Ansys HFSS, Designer and Multiphysics software to predict mechanical and electrical performance. The use of these tools permit insight to the performance and allows optimization of the interconnect to high possible performance level at the earliest stage of design, allowing these optimization features to be native to the interconnect.
Our machine shop is capable of producing quick-turn samples in two weeks, enabling fast track design to support your product development. This quick-turn capability permits validation and correlation to simulations of your interconnect to ensure product meets your performance requirements before product is shipped. Sharing of testing and qualification testing assists you to fast track your development process.

Winchester Fiber Optic Capabilities

With a vast array of polishing fixtures, interferometer adapters, and test equipment adapters, and over 100 years combined fiber optic termination expertise, we can terminate and test any cable or connector you have. Even if you have a custom ferrule with no commercial polishing fixture available, we will develop and build a custom polishing fixture to solve your application need. In-stock polishing fixtures are available for quick turnaround manufacturing on commercial connectors such as LC, FC, SC, ST, MU, MTP, MT-RJ, and military ferrules such as ITT ruby ferrule, ITT PHD, 29504/14 and /15, and specialty connectors such as FDDI, ESCON, Biconic, SMA, D4, and SMPTE304.

Product Design and Development
Winchester Interconnect engineers use highly-advanced, best-in-class software tools, equipment, and technologies during the design, development, and verification/validation phases of their projects. Parts are first designed in a 3D CAD environment and then simulated to obtain an optimum 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.
Optical Simulation
The two types of widely-used fiber optic interconnects can be characterized as ferrule-based or free space. For ferrule-based connectors, it is critical to maintain appropriate compressive forces on the fiber interface in addition to appropriate mechanical tolerances on the ferrules and alignment sleeves so that physical contact is maintained between the end faces of the optical fibers. For free space interconnects and devices, optical simulation of the light beam behavior in free space is the key requirement. Winchester Interconnect has fiber optic interconnect design and simulation tools to cover both interconnect scenarios. This allows design of predictable insertion and return losses over changes in temperature and under conditions of shock and vibration. Design is done through advanced modeling of the interface using the interface before physical samples are created.
Fiber Interface Modeling & Simulation Tools
3D Solid Modeling using Solidworks®
Early design cycle simulation using Ansys® Multiphysics® to simulate mechanical forces
Optical simulation of any free space beams and optical surfaces and coatings using Photon Inc. FRED software. Gaussian beam decomposition is used for single and multimode beams, while ray tracing capabilities are also available for large core fiber applications.
Characterization and verification of prototypes using physical testing
Environmental testing of finished connector to verify optical performance
Mechanical Analysis of the Fiber Optic Connector
Spring and latching forces are calculated to ensure the system will maintain appropriate pressure at the optical interfaces.
Free Space Optical Analysis
Photon Inc. FRED software uses advanced modeling techniques beyond ray tracing to simulate coherent sources and calculate single-mode or multi-mode fiber insertion losses.
Standard lens catalogs and custom designed lenses and coatings are used within the system to duplicate the optical arrangement within the connector or device interface.
Optical Testing
Winchester Interconnect Optical Lab includes a variety of test equipment for optical measurement and evaluation. This includes JDS insertion and return loss test equipment with standard 850, 1310 and 1550nm, in addition to custom wavelength multimode and single mode light sources for testing at virtually any wavelength, launch condition and fiber type. Reference leads are stocked for all major single and multi-fiber optical connectors including non-standard military ferrule sizes, MT multi-fiber ferrules, and free space lens-to-fiber coupling. Interferometric physical inspection is available to characterize the fiber end face.

Environmental chamber linked to JDS multi fiber test equipment allows optical insertion and return loss testing while under environmental stress.
