This document is intended to provide reliability assurance recommended practices for the deployment of individual photonic devices and PIC-based devices into aerospace platforms, focusing on reliability requirements to reach Technology Readiness Level (TRL) 7, 8 and 9. It will cover reliability assurance tests for single element and PIC chips, packaged single element and PIC chips and some single element and PIC based higher functionality modules, such as fiber-optic transmitters and receivers, free space optical transmitters and receivers, illuminators and sources for optical sensors. The document will provide the reasons and methods for aerospace reliability assurance of PIC chips, PIC based packages and PIC based devices. It will be as inclusive as possible, including PIC chips fabricated in the main material systems: semiconductors (Group IV, III-V, II-VI), electro-optic crystals (lithium niobate) and polymers.
To detail the different epoxy types available for different aerospace applications which require different temperature ranges. Explain incoming/final inspection requirements and storage requirements. Examine the epoxy chemical make up with explanations of purpose in performance.
This SAE Aerospace Standard (AS) defines fiber optic fusion splicers acceptable for the installation and repair of fiber optic interconnects in aerospace applications. Two different application environments are defined, depending on whether there is risk of flammable vapor or hazardous atmosphere being present. Equipment suited to flammable or hazardous environments may be over specified for factory, depot, or other relatively safe environments. To address these different application environments, two types of fusion splicer will be specified in applicable detail specifications: Type I. For hazardous environments specifically including potentially flammable or explosive atmospheres. Type II. For environments in which it is established that there is no risk of flammable or explosive vapors being present.
Describes the different types of epoxies, methods of mixing, installation and inspections into optical connectors/terminus. Illustrate typical examples of processing equipment and tooling. Highlight critical parameters and potential failure modes during epoxy processing.
To create a standard that instructs both supplier and user in the testing and characterization of initial build fiber optic cable assemblies for avionics/aerospace applications. This can be in the plant or in the avionics “box.” It includes specification of jumpers (aerospace measurement quality jumpers), end faces, link loss requirements and inspection.
ARP6366 defines a comprehensive and widely-accepted set of specification guidelines to be considered by those seeking to use or design fiber optic sensors for aerospace applications. Some of the most common applications for fiber optic sensing within aerospace include inertial guidance and navigation (gyros) and structural monitoring (temperature, strain, and vibration sensing). Common sensor infrastructure elements include: transmitting and receiving opto-electronics (e.g., sources and receivers); multiplexing and demultiplexing optics; optical cabling; and signal processing (both hardware and firmware/software).
This document provides guidance on key areas of system design to achieve high performance and high reliability for mission critical aerospace systems and platforms. The fundamental element of a reliable, functional aerospace fiber optic application is the system design. It is the system designers’ task to define the methods, components, installation and processes supporting the transmission of the optical signal through the platform, while providing a physical layer with the necessary performance, reliability, and readiness for the application.
The goal of this document would be to control specific configurations of epoxies approved for aerospace. Providing a structured standard for configuration control of epoxies and appropriate applications and areas of use for multiple grades and environmental performance considerations.
This document is intended for discrete and integrated digital, wavelength division multiplexing (WDM), and analog/radio frequency (RF) photonic components developed for eventual transition to aerospace platforms. The document provides the reasons for verification of photonic device life test and packaging durability. The document focuses on pre-qualification activity at the optical component level to achieve TRL 6. The recommended tests in this document are intended to excite typical failure mechanisms encountered with photonic devices in an aerospace operating environment, and to build confidence that a technology is qualifiable during a program’s engineering and manufacturing development phase. This recommended practice is targeting components to support electrical-to-optical, optical-to-electrical, or optical-to-optical functionality. Passive optical waveguide, fiber optic cable, and connector components that are integral to a photonic package are included.
