2 In 1958, W. L. Gore & Associates was founded with the mission to Broad fiber optic capabilities for military and aerospace applications: develop new capabilities based on fluorocarbon polymers, especially polytetrafluoroethylene (PTFE) and expanded Pre-formed assemblies, fan-outs, custom bundle assemblies, cable, and connectors polytetrafluoroethylene (eptfe). For nearly 50 years, Gore has been driven by the challenge of creating innovative, standardsetting products that are revolutionary in their effect. From high-performance Hybrid optical / copper assemblies fabrics used in the most hostile environments, to stent grafts that repair threatening aneurysms in the human body, to electronic components used in outer space exploration, Gore has the heritage of developing innovative products that perform in the History of solving challenging cable and assembly problems harshest conditions, meet scientific, fitness-for-use quality life-testing, and are offered throughout a variety of industries.

3 Fiber Optics for aerospace and military applications Competitive Advantage through Fiber Optic Capabilities Gore provides high performance fiber optic cables, assemblies, and custom packaging for military and aerospace applications. Because of Gore s long heritage with the military and aerospace industries, GORE Products better address the unique requirements of military and aerospace system designers. When compared to telecomgrade fiber optic products, GORE Mil-Aero Fiber Optic Products offer improvements in operating temperature range, vibration, mechanical shock, tension, minimum bend radius, chemical resistance, and overall ruggedness without compromising size or flexibility. eptfe and Fiber Optics Traditional fiber optic cable materials affect the well-known optical stability of a bare fiber. GORE Fiber Optic Cable is differentiated from traditional cable by an expanded PTFE buffer system that effectively decouples the optical fiber from other cable elements. As a result, optical performance of a GORE Cable closely approximates that of a bare optical fiber, even under mechanical or thermal stresses. This differentiating technology is common to all GORE Fiber Optic Cable products: ribbon interconnects, high strength tether cables, hybrid round cables, and simplex cables. Why Gore Gore is broadly experienced in all military and commercial interconnects, fiber types and coatings. A full range of Deutsch connectors, MIL-DTL connectors, as well as commercial connectors from simplex to MT ribbon connectors are available on GORE Fiber Optic Assemblies. Gore engineers are ready to respond to your custom assembly and harness requirements working handin-hand with your design engineers. Whatever the requirements, Gore can work from your 3D CAD files and respond with preformed, rapid prototypes. Gore has the product portfolio and experience to offer a wide array of solutions with the required performance.

4 Fiber Optics for aerospace and military applications Solutions Start With Cable Gore offers a variety of fiber optic cable options that address the unique requirements of military and aerospace system designers. GORE Fiber Optic Cable offers improvements in operating temperature range, minimum bend radius, chemical resistance, and overall ruggedness without compromising size or flexibility. Cable forms include ribbon, 0.9mm, 1.2mm, and 1.8mm simplex. Solving Installation Challenges With Pre-Formed, Robust Assemblies The customer s mil-aero box assembly left little room to route a fiber optic interconnect. Many installers do not specialize in fiber optic installations and are unfamiliar with the requirements and procedures to effectively install fiber optics without exceeding minimum bend radius. A ribbon fiber assembly s MT interface had to transition to a MIL-DTL connector while meeting EMI limits and atmospheric pressure sealing. Extreme temperature, harsh shock and vibration testing also had to be passed for complete qualification. Gore created a drop-in solution that met all the challenges. Working from the customer s CAD files, Gore designed a pre-formed assembly easing installation. A custom MIL-DTL backshell solved the EMI and pressure sealing requirements, while the use of 125 C rated optical fiber allowed the GORE Assembly to pass all military qualifications.

Solution included: GORE MT Interface to MIL-DTL connector Pre-formed assembly Custom EMI backshell Stable performance from -40 C to +125 C Full military qualifications Products operate in a variety of operating temperatures from -65 C to +150 C and offer tight bend radii. Spaceflight qualified cable is also available. Regardless of your cable requirements, Gore has a solution. Optimized Packaging Engineered and optimized for Quick Turnaround your application Rapid prototyping, even with custom cable Work from 3D CAD files Automated production termination available Minimized routing complexity Eases fiber optic installation Pre-formed assemblies, fan-outs, custom bundled assemblies Solving Performance Challenges In Extreme Temperature Performance Mil-aero applications often involve extreme environmental limits, including extreme temperatures, which can affect the performance of an assembly if it is not designed to withstand these limits. Application Engineering support Performance Glass optical fiber itself is robust, but its optical loss can be severely affected Unmatched stable optical performance Extreme temperature, shock, and vibration performance Crush and tensile load resistance assemblies by how it is packaged and protected in an assembly. The 80 0 stiffness and thermal 60 expansion of glass -5 and the materials 40 used in assemblies are vastly different Micro-bending induces -15 Gore advantage loss as a result of -20 mismatches of material -20 properties. -25 Gore Design Brand X Design Temp This single-mode fiber Time (minutes) application required mil-aero environmental exposures. The competitive solution experienced large micro-bending optical loss at cold temperatures. Gore engineered a robust assembly that solved this problem and provided optical stability (<1dB) across all environmental conditions. Change in Transmittance (db) Solution included: MT ribbon connector fan-out to MIL-T terminations Gore materials with stable performance from -40 C to +85 C Robust, molded fan-out Full military qualification Solving Installation Challenges With Pre-Formed, Robust Assemblies Gore worked with a customer on a shipboard application which involved tight backplane routing of fiber optic assemblies. The installers did not specialize in fiber optic installations and assembly failure due to overbending was a concern. The original design required a complex clamping system. Gore developed a fiber optic pre-formed assembly solution that eliminated the complex clamping system. Working from customer CAD files, the GORE Pre-formed Assembly made installation simple. The GORE Assembly used a cable resistant to the crushing caused by clamping under heavy shock and vibration. An example of a Gore solution is shown above. Solution included: Amphenol LRM connectors to MIL-T terminations Pre-formed assembly for simplified installation Crush resistant cabling for harsh shock and vibration exposure Temperature (C)
