Abstract

Dalam penelitian ini, deteksi rugi intensitas serat optik akibat perubahan suhu pada rentang 40°C – 200°C dilakukan dengan memanfaatkan Single-mode FC Splitter 1×2 (50:50). Pengukuran rugi intensitas dilakukan menggunakan Optical Spectrum Analyzer (OSA) Agilent 86142B dan Optical Power Meter (OPM) JDSU OLP-35. Probe serat optik dibuat dengan pengupasan pada ujung masukan serat, dengan panjang kupasan 26.8 mm dan 35 mm. Pengupasan dilakukan menggunakan metode konvensional yaitu dengan etching kimia, sehingga cladding serat optik berupa udara. Probe serat optik dapat mendeteksi adanya perubahan suhu dikarenakan fenomena gelombang evanescent dan konsep refleksi. Rugi intensitas probe serat optik meningkat secara linier seiring dengan meningkatnya suhu. Hasil pendeteksian perubahan suhu paling linier terjadi pada Sampel 1 (panjang kupasan 26.8 mm) dengan detektor menggunakan OSA Agilent 86142B. ========================================================================================================= In this study, the detection of optical fiber intensity loss due to temperature changes in the range of 40 °C – 200 °C was carried out using Single-mode FC Splitter 1×2 (50:50). Measurement of intensity loss is using Optical Spectrum Analyzer (OSA) Agilent 86142B and Optical Power Meter (OPM) JDSU OLP-35. Optical fiber probes are made by partially unclad at the end of the fiber input, with stripping length of 26.8 mm and 35 mm. The partial uncladding was carried out using conventional methods, namely chemical etching technique, so that optical fiber cladding in the form of air. Optical fiber probes can detect changes in temperature due to the evanescent wave phenomenon and the concept of reflection. The optical fiber probe intensity loss increases linearly as the temperature increases. The results of the detection of the most linear temperature changes occurred in Sample 1 (stripping length of 26.8 mm) with a detector using OSA Agilent 86142B.
