Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh perubahan suhu dan perubahan panjang kupasan cladding serta coating terhadap nilai rugi daya yang dihasilkan oleh fiber optik multimode silika tipe G-651. Rugi daya yang dihasilkan diukur dengan alat ukur optical power meter. Variasi panjang kupasan yang digunakan yakni 2 cm, 3 cm dan 4,7 cm. Pengukuran rugi daya dilakukan tiap perubahan panjang kupasan dan perubahan suhu dari sumber pemanas berupa lampu bohlam dengan daya 100 watt. Perubahan suhu diukur tiap kenaikan dan penurunan 1°C dari suhu awal. Panjang gelombang pada power source yang digunakan yakni 1310 nm dan 1550 nm. Hasil penelitian menunjukkan bahwa semakin besar panjang kupasan cladding dan coating serat optik menyebabkan nilai rugi daya semakin besar. Pada panjang gelombang sumber 1310 nm sensitivitas dari serat optik terhadap perubahan suhu lebih tinggi jika dibanding dengan sensitivitas dari serat optik dengan panjang gelombang sumber 1550 nm. Perlakuan pemberian suhu yang semakin tinggi mengakibatkan nilai intensitas daya keluaran yang ditangkap optical power meter semakin menurun, yang menunjukkan terjadi banyak rugi daya pada fiber optik yang diuji. ====================================================================================================== This experiment to determine the effect of temperature changes and peeling length changes of cladding and coating on power loss of multimode optical fiber types of silica G-651. The resulted of loss was measured by an optical power meter. Variation cladding and coating peeling length in this experiment is 2 cm, 3 cm and 4,7 cm. Power loss measurement was conducted in temperature changes and peeling length changes with heating source light bulb 100 watt. Temperature changes were measured in every increasing and decreasing temperature of 1°C of the initial temperature. Wavelength variation in the power source used the 1310 nm and 1550 nm. The result from this experiment show that the greater peeling length of optical fiber cladding and coating cause the losses is getting bigger. At a wavelength source of 1310 nm, sensitivity of optical fiber to temperature changes is higher when compared with the sensitivity of optical fiber with a wavelength source of 1550 nm. The higher of temperature, result that the value of output power intensity is decreasing which shows a lot of loss in optical fiber.
