“…In a previous work, we verified that the performance of these fibers when the temperature was changed inside the operating ranges recommended by the manufacturer was unaltered [15]. Here, we tested the variation with temperature of transmitted power and BER for both SC-POFs intentionally exceeding their high temperature limits.…”

Plastic optical fibers (POFs) have been proposed and implemented in the avionics environment lately, and temperature is naturally a big factor that can affect their performance in those platforms. We present an experimental characterization of the transmission properties of POFs comparing the performance of standard fibers with that of fibers designed to sustain high temperatures, such as those on avionics platforms. We tested different step-index 1-mm poly(methyl methacrylate) single-core and multicore fibers. Frequency response, bit error rate (BER), attenuation, and output power distribution were measured for each fiber type at room temperature. In addition, BER and fiber attenuation were monitored as a function of temperature, intentionally exceeding the temperature limits to obtain the true temperature ranges and to assess the performance penalty. The same properties were obtained for the overheated fibers and compared to those for nonheated fibers of the same type to reveal permanent performance degradation.

“…Heat-resistant PMMA fibres with thermoset jackets have a higher temperature limit of 105 °C, as thermoset polymers crosslink together during the curing process to form an irreversible chemical bond that eliminates the risk of melting when heat is applied [ 106 ]. Although their attenuation and bandwidth are slightly poorer than those of standard fibres, it was shown that they are able to withstand temperatures up to 125 °C, beyond their nominal limit, with negligible changes in performance [ 107 , 108 ].…”

We report on recent advances in the use of inexpensive polymer optical fibres (POFs) for sensing applications in avionics. The sensors analysed in this manuscript take advantage of the unique properties of polymers, such as high flexibility, elasticity, and sensitivity, and they range from strain, elongation, and vibration interrogators to level and temperature meters, leading to cost-effective techniques for structural health monitoring in aircraft structures. We also highlight recent power-supply methods using Power-over-POF in order to feed sensors remotely, and we discuss the constraints imposed by connectors on the performance of POF networks in aircrafts.

“…Also, fiber installation in compact environments such as cars, planes and houses implies pressuring and bending the fiber [32]. Moreover, in some of these settings, the fiber can be subjected to harsh environmental conditions [35]. Therefore, the fiber model should describe its behavior, precisely encompassing all sources of variability while simultaneously optimizing computation time.…”

The application areas for plastic optical fibers such as in-building or aircraft networks usually have tight power budgets and require multiple passive components. In addition, advanced modulation formats are being considered for transmission over plastic optical fibers (POFs) to increase spectral efficiency. In this scenario, there is a clear need for a flexible and dynamic system-level simulation framework for POFs that includes models of light propagation in POFs and the components that are needed to evaluate the entire system performance. Until recently, commercial simulation software either was designed specifically for single-mode glass fibers or modeled individual guided modes in multimode fibers with considerable detail, which is not adequate for large-core POFs where there are millions of propagation modes, strong mode coupling and high variability. These are some of the many challenges involved in the modeling and simulation of POF-based systems. Here, we describe how we are addressing these challenges with models based on an intensity-vs-angle representation of the multimode signal rather than one that attempts to model all the modes in the fiber. Furthermore, we present model approaches for the individual components that comprise the POF-based system and how the models have been incorporated into system-level simulations, including the commercial software packages SimulinkTM and ModeSYSTM.
