Abstract

Recently, concerns have been raised about the performance of mechanical fiberoptic splices in high humidity environments. These have arisen due to the introduction of lower-cost, free-breathing splice enclosures, which, since they are not sealed, allow the entry of moisture, and potentially allow condensation on the splices. In order to determine whether or not high humidity is a reliability issue, we conducted two series of laboratory tests with a variety of different splices, including both fusion splices and mechanical splices. In addition, we made visual observations of the effect of a high humidity environment on simulated splices, which were assembled using gel-filled glass capillary tubes. Our laboratory tests exposed the splices for prolonged periods to a high-temperature, high-humidity environment of 75 degree(s)C/95% relative humidity (RH), with periodic excursions down to 25 degree(s)C/95% RH, and to -25 degree(s)C with uncontrolled humidity. We found some splice failures that could be correlated to the onset of high humidity, and we conclude that some types of mechanical splices potentially could fail in such an environment. In this paper we will describe our experimental setup and data collection process, and present the results of the experiments.
