Dalam penelitian ini telah dilakukan fabrikasi dan karakterisasi directional coupler konfigurasi 3×3 susunan segitiga berbahan serat optik plastik step index multimode tipe FD-620-10 dengan panjang kupasan 35 mm, 40 mm, 45 mm, 50 mm, 55 mm, dan 60 mm menggunakan pendekatan metode fused biconical tapered (FBT). Hasil karakterisasi directional coupler menggunakan BF5R-D1-N diperoleh bahwa panjang kupasan 45 mm dengan input pada port A1 menunjukkan nilai coupling ratio CR = 0,6; 0,2; 0,2 dan excess loss Le = -7,76 dB, pada port B1 menunjukkan nilai CR = 0,2; 0,6; 0,2 dan Le = -6,76 dB, pada port C1 menunjukkan nilai CR = 0,2; 0,19; 0,61 dan Le = -6,75 dB. Directional coupler ini paling baik digunakan sebagai piranti dalam sensor.
