SAE Aerospace Recommended Practice (ARP) 6318 Aerospace Photonics Technology Readiness Advancement and Insertion via Verification and Validation of Active Photonic Device Reliability and Packaging Durability is an outgrowth of lessons learned by airborne platform defense acquisition professionals and defense civilian and contractor subject matter expert professionals interested in transitioning fiber...
MIL-STD-1678 specifies requirements that address airborne platform fiber optic system total ownership cost factors including performance, cost, supportability, maintainability, reliability, durability, producibility, quality, and safety.
In all trials, both measured forces spiked sharply upon end face contact. The optical power throughput plateaued for an insertion distance of nearly 2 mm before decreasing due to fiber bending outside of the capillary. This plateau corresponded to insertion losses as low as 0.12 dB, and was typically below 0.3 dB. Our results show that these force spikes strongly coincided with the maxima in optical...
The aerospace environment presents a formidable research and engineering challenge for designing, packaging and qualifying components for avionics-grade, active and passive, single-mode wavelength division multiplexing (WDM) [1]. New optoelectronic package interface and optical subassembly designs are currently under development for single-mode avionics WDM local area network (WDM LAN) as well as...
A wavelength-routed WDM node was demonstrated to allow error-free transmission of digital optical signals between 4 inputs and outputs at all tested data rates. Even with the addition of 29.4 dB loss, data transmission through the node remained below 10e-12 at the target data rates of 1.25 and 2.5 Gbps. Though developed to support the cross-cube topology, this node is flexible enough to work within...
The concept of built-in test (BIT) applied to aerospace platform fiber optics has been discussed for over three decades.1–2 Today the practical realization of a digital fiber optic transceiver with transmitter signal strength indication (TSSI), receiver signal strength indication (RSSI), and in situ optical time domain reflectometry (OTDR), gives the aerospace industry a new point of departure to...
Over the past decade the maturation of digital avionics fiber optics technology has resulted in the update or creation of several defense/aerospace standards that did not exist a decade ago. These new-era standards address airborne/aerospace platform fiber optic interconnects including connectors, cables, fibers, splices, cable assemblies, harness installation, digital fiber optic system design, and...
In this paper we have described the development of a novel fiber optic cable restoration technology based on field-portable fiber tip shaper and mechanical splicer devices. The cable restoration procedure accommodates aerospace simplex fiber optic cable, fiber with both strippable and un-strippable coatings, produces no hazardous waste (glass shards), requires little training and virtually no preventative...
