This SAE Aerospace Information Report (AIR) is devoted to the challenges of applying optics to new advanced RF analog systems only; digital data link applications are covered elsewhere in protocol/architecture specific documents like Fibre Channel, ATM, Ethernet, Sonet, etc. This document has four main goals: 1 To completely cover today’s capabilities and limitations of fiber in meeting multiple types of advanced RF system requirements. 2 To discuss near term advancements being developed that will bring us closer to meeting all the capabilities of current copper coax systems. 3 To identify the benefits of fiber optics for RF systems 4 To identify challenges for future development.
This specification covers the performance requirements for a plug and receptacle, multiple termini, fiber optic connector. Fiber optic connectors using removable termini, and are capable of operating within a temperature range of -65 to +200 °C (see 22.214.171.124). These connectors are supplied under MIL-STD-790 reliability assurance program. Statistical process control (SPC) techniques are required in the manufacturing process to minimize variation in production of connectors supplied to the requirements of this specification.
This ARP document will provide guidelines for optical performance testing of short haul fiber optic inter-connection systems used in aerospace vehicles. The focus of this document is to establish common pre and post installation test methods and troubleshooting methodologies.
This SAE Aerospace Information Report (AIR5271) covers the basic attributes of a second-generation robust, reliable high-density fiber optic interconnect system for aerospace applications. The intent is to take advantage of recent commercial developments in materials, components and manufacturing methods to develop rugged high-density fiber optic interconnects optimized for aerospace and automotive applications, which can accommodate a variety of optical fiber waveguide types. These waveguide types include single mode and multi-mode glass/glass fibers and waveguides, plastic clad silica fibers and waveguides, and all polymer fibers and waveguides. This second generation interconnect system should represent a dramatic improvement over first generation. The cable should be extremely robust eliminating any concerns over cable damage or fiber breakage in an aerospace environment.
This specification applies to a communication protocol for networked control systems. The protocol provides peer-to-peer communication for networked control and is suitable for implementing both peer-to-peer and master-slave control strategies. This specification describes services for all seven protocol layers. In the layer 7 specification, it includes a description of the types of messages used by applications to exchange application and network management data.
This specification covers design and performance requirements of fiber optic splices for optical distribution systems in aerospace vehicles and provide a means of procurement of such devices. Fiber optic cable design characteristics are uniquely related to various aerospace vehicle applications. As a result, the splice is constructed for specific cable types. Evaluation of the splice performance shall be with the cable type as defined in the splice detail specification (see Section 3). Typically, fiber optic splices have unique assembly instructions. Splices that are qualified to the same detail specification must be assembled using the same procedure and tools. All assembly instructions shall be presented and documented in accordance with this specification.
This document defines requirements for digital, command/ response time division multiplexing (data bus) techniques for fiber optic implementation. The concept of operation and information flow on the multiplex data bus and the functional formats to be employed are also defined.
