AbstractNow a day all the telecommunication industries are using fibers for faster data communication and long distance communication. Fibers use light as the information and it is carried over long distances. Optical fiber has large advantages over a copper and co-axial cable because of its lower attenuation and interference. Optical time domain reflectometer (OTDR) is also one of the important devices using in telecommunication industries to characterize an optical fiber. This article deals with the study of long distance backbone single mode fiber and their features are discussed with the use of an OTDR. The results of this article focused on the losses and breaks of the fiber with the events. The Single mode OTDR is used to find the events, losses and breaks of the backbone fiber between the two locations. This work will give a way to study the nature of optical fibers and understand the practical application of optical fiber communication.

Reflectometric measurements of thermally expanded core area In this work an analysis method of one-way optical time domain reflectometer (OTDR) measurements has been presented. This method uniquely confirms mode field radii matching in diffusion transit area of the thermally expanded core (TEC) of thermally connected single mode telecommunication fibers. A comparison of reflectometric measurements with theoretical calculations of losses in TEC areas has been demonstrated.

Pada penelitian ini telah dilakukan analisis Rugi-rugi redaman yang dipengaruhi oleh lengkungan dengan beberapa variasi jari-jari lengkungan pada sistem komunikasi serat optic di jaringan FTTH. Ada tiga titik kabel serat optik yang akan diukur dengan jenis Single Mode Step Index pada panjang gelombang 1310 nm. Alat bantu yang digunakan adalah Optical Time Domain Reflectometer (OTDR) tipe ANRITSU. Data dari pengukuran akan dibandingkan dengan data dari analisis perhitungan guna mencari nilai daya terima. Metode yang digunakan adalah power link budget dan power loss fiber. Dari hasil penelitian ini didapatkan bahwa saat jari-jari sebesar 0.3 cm dihasilkan nilai Rugi-rugi sebesar 13.6921 dB, sehingga nilai daya transmisi sebesar 60 dB berkurang menjadi 46.3079 dB. Besar nilai jari-jari lengkungan berbanding terbalik dengan nilai Rugi-rugi redaman. Namun berbanding lurus dengan nilai daya terima. Adanya variasi jari-jari lengkungan dengan sudut lengkungan rata-rata 75.730 yang masih layak terhadap sudut kritis 45.280dan panjang serat optik dapat mempengaruhi besar kecilnya nilai Rugi-rugi yang akan dihasilkan serta daya terima pada sistem dengan rata-rata presentase error persen tidak melebihi 1%.

An optical fiber is a high-speed telecommunication transmission medium. Principally, an optical fiber is made of a very fine glass fiber material, which is able to transmit light waves using light reflection method on the surface of the fiber optics core. An underground installation of the fiber optics makes this device robust from external interferences. However, the fiber optic cable performance should always be checked to maintain performance during data transmission process. One way to test fiber optics cable performance is by using an Optical Time - Domain Reflectometer (OTDR) device. This device sends a light wave from one point of the fiber optics cable. The light wave then returns when reaching the other point of the fiber optic cable while carrying some measurement parameters especially the physical length and attenuation of a fiber optic cable. The evaluation of the fiber optics cable performance requires the preparation, installation, and configuration of the OTDR. In this paper, we conducted evaluation on the performances of fiber optics cable. The data generated by the performed evaluation indicated an occurring attenuation on the fiber optics cable along 64.402 km of its lengths.
