Reliability is important to how a fiber optic system performs, but how is it measured and how does that affect fiber optic system design? Complex avionics today typically have internal clocks that measure operational times. This data cannot be read at the squadron level and must be obtained by the intermediate or depot level repair facilities. Operational time-to-failure would be valuable information to have, but is unavailable through the military aircraft maintenance data system

The authors have developed a tunable laser technology based on optical pumping of Yb and Er doped high phosphate glass (Laporta, 2001). Er doped glass is widely used for fiber amplifiers in the 1550nm wavelengths. High phosphate glass permits very high doping of Yb and Er so that small cavity length solid-state lasers can be built. Methods for tuning these lasers include rotating glass etalon and tunable Bragg fiber. We have developed a tunable laser using piezoelectric moveable mirror for mode selection and cavity tuning. The properties of these lasers are high SMSR and low RIN

In this talk, we will introduce a commercially available optical frequency domain reflectometry (OFDR) technique and its applications in avionics fiber-optics. We will provide multiple measurement examples within the avionics field not currently supported by conventional test tools or methods including high-resolution fault detection and distributed fiber sensing

In this paper, an architecture for an optically-switched avionics network is presented. The performance of this architecture was analyzed using simulative experiments for two wavelength allocation strategies. Additionally, the effects of varying the timeslot period and maximum number of consecutively allotted timeslots were analyzed. Results showed slightly lower packet latencies with a fixed-destination wavelength protocol. Larger timeslot periods, up to 1,000 ns, also improved performance, although further increases would not be beneficial. The optimal parameters for any platform will always depend upon the nature of the network traffic. Our modeling tools and approach allow us to evaluate such design decisions for a wide range of network scenarios

Historically, coaxial and shielded twisted pair cables have found widespread usage for high frequency data transmission within satellites, military systems, and avionics applications. As data rates continue to increase, copper-based cable transmission is reaching its practical limit, and out of necessity system designers are implementing optic-based systems. To meet performance objectives, system designers need to understand the behavior of fiber optic cable assemblies in harsh environments

Critical to the viability of any common system architecture across platforms are: (1) the demonstration of the interoperability of key functional "building blocks"; (2) the definition of standard internal and external OE interfaces; (3) the proven scalability for key components; and (4) the long-term availability of "standard" components

Currently available standard acrylate coated fibers have a maximum operating temperature range of +85degC. However, recently several fiber manufacturers have introduced new types of high temperature acrylate coated fiber with temperature handling up to +150degC for long term and +200degC for short term. These fibers are marketed as HTA (high temperature acrylate) fibers, but rarely does the qualification testing include jacketed, cabled fiber constructions. This paper describes the work being done to characterize the thermal stability and functionality of a HTA fiber in a cable construction where all base materials (except the fiber) are rated for constant use at +260degC

The SAE AS3 avionics fiber optics standardization committee has recognized a need for a testing and inspection document for beginning of life of fiber optic cable assemblies used in military/aerospace applications. The intent of the document is to provide a standard that the supplier can use to inspect and test cables prior to shipment to the customer, then when the customer receives the cables, the assemblies can be checked in the same manner to verify both results are the same. The SAE subcommittee assigned the writing of this standard to the AS3C3 JELLI sub-group for jumpers, endface, link loss and inspection
