Abstract:

Optical fiber technology has developed quite rapidly. However, one of problems on fiber optics that is losses consequence attenuation connection which caused by the core material of the optical fiber (core) is dirty and the light is bent in the wrong direction. Optical fiber splicing in this study used a Sumitomo Z1C Optical Fiber Fusion Splicer, while to measure the splicing results an Optical Time Domain Reflectometer (OTDR) was used. Yokogawa AQ1000 with single mode fiber optic type. The aim of this research is to minimize the amount of connection attenuation based on cleanliness and cutting fiber optics on moment connection. Based on testing which has been carried out, it is obtained that the difference in attenuation results is due to the attenuation value measured by the fusion splicer being mark estimation loss be measured by sensors camera namely a microscope objectives lenses whereas results the attenuation value measured by the OTDR is a real value measured using an APD (Avalanche Photodiode) sensor. For quality connection most Good obtained connection attenuation most small as big as 0.00 dB on fusion splicer And measurement OTDR of 0.103 dB with cleaning fiber optics which it has been peeled using tissue and alcohol, then immediately connected and used for cutting techniques fiber optics most good attenuation produce most small that is 0.00 dB on fusion splicer and 0.098 dB in OTDR measurements by cutting optical fiber with a fiber cleaver placed on a flat surface with a high fiber cleaver knife speed, namely within 0.16 seconds.
