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%.
