Description
Summary:This article develops a life test plan for a standard optical splitter, which provides insight into its lifetime and reliability R (t). According to the GR-2866 standard, the environmental variables to be analyzed are temperature (T) and humidity (H) and 12 samples must be run. During the analysis, 720 cycles of T and H were performed during a 30-day trial period (Temp. = 85 °, -40 ° and Hum. = 85%). Thus, in order to reduce the test time, using the Taguchi method, the most significant temperature range was determined. With this new test temperature range (T = 100 °, -45 ° and H = 85%) in the Coffin-Manson model, the new test time was 10.33 days. The experimental tests were carried out using an environmental camera and optical equipment that allowed measuring the amount of attenuation in decibels (dB) caused by stress from temperature and humidity. For this new test range the Weibull parameters are β = 3.19 and η = 92.47.
