This article focuses on the analysis of the selected optical coupler parameter which have been thermal stressed for 30 weeks at temperature 95 °C ± 5 °C. Optical couplers with 10:90, 1:99 and 50:50 dividing ratio were tested. A total of 6 optical couplers were tested. Measurements were made for two wavelengths 1310 nm and 1550 nm. The observed parameter was the insertion loss. The insertion loss is very important parameter because the fiber-optic passive components (such as optical couplers) disrupt signal transmissions as the continuous core of the optical fiber carrying the signal mates with the component in a manner that causes some amount of scattering and reflection of light waves. The degree to which the signal has been depleted is described as insertion loss, which is the undesired attenuation of the signal measured in decibels (dB).
