<![CDATA[ABSTRAK Penelitian ini menganalisis rugi-rugi serat optik terhadap sistem komunikasi serat optik di PT. Telkom ARNET 1 Bandung Timur, menggunakan kabel serat optik multimode tipe G 655 C dan G 652 D. Berdasarkan hasil pengukuran menggunakan OTDR didapat total loss maksimum yang melebihi standarisasi 0,5 dB/km, terjadi pada ruas Ahmad Yani-Tegalega, kabel 24 core dengan nomor serat 1,2,5,6,7,9,11 dan ruas Ahmad Yani-Tegalega, kabel 48 core dengan nomor serat 35,37,38. Ruas Ahmad Yani-Dago total loss maksimum yang melebihi standarisasi 0,5 dB/km yaitu pada nomor serat 18. Daya terima minimum standarisasi adalah - 4 dBm untuk sumber cahaya laser. Dari hasil pengukuran didapat daya terima minimum untuk ruas Ahmad Yani-Lembong 1,4 dBm, Ahmad Yani Tegalega - 2,893 dBm, Ahmad Yani-Ujungberung 0,932 dBm, Ahmad Yani- Turangga 1,4 dBm, dan Ahmad Yani-Rancaekek -0,702 dBm. Kata kunci : serat optik, standarisasi loss ITU-T, daya terima minimum, OTDR ABSTRACT This reseach analyzing loss optical fiber to the optical fiber communication systems in PT. Telkom Arnet 1 Bandung Timur, using the multimode optical fiber cables, type G 655 C and G 652 D. Based OTDR measurement results, it was obtained the total loss exceeded the maximum standarization of 0.5 dB/ km that occurred on a segment Ahmad Yani-Tegalega, 24 core cable with fiber numbers 1,2,5,6,7,9,11. The segment of Ahmad Yani-Tegalega, 48 core cable with fiber numbers 35,37,38 and Ahmad Yani-Dago total loss exceeded the maximum standarization of 0.5 dB/km was the number of fiber 18. The minimum received power standarization was - 4 dBm for the laser light source. The obtained measurement results for the minimum received power segment Ahmad Yani-Lembong, Ahmad Yani-Tegalega, Ahmad Yani-Ujungberung, Ahmad Yani-Turangga and Ahmad Yani - Rancaekek were 1.4 dBm, -2.893 dBm, 0.932 dBm, 1.4 dBm and -0.702 dBm respectively.
