    The research on analysis and determination of attenuation of optical fiber cables used in telecommunication system at PT. Chevron Pacific Indonesia has been done. Optical fiber that is used is a single mode step index type G.652. Transmitting light in the optical fiber is damped that is physically caused by absorption, losses on optical fiber, switching losses and connector losses and other physical damage. Network testing was done at wavelengths of λ=1310 nm and λ=1550 nm on 6 tracks. OTDR (Optical Time Domain Reflectometer) M200 series and the transmitter network of transmitting optical signals were used for measurement. The method used in this measurement is budget link, in order to measure the performance of communication system of the optical fiber cables as a result of attenuation that occurs along the cable. From measure result by OTDR M200 got highest attenuation is in the IT Tower link to ACME Office at a distance of 1,2 km, with a total attenuation value of 11.5 dB. Attenuation was caused by the lack of impurities of optical fibers and the process of splicing. On the Rangau link to Pelita MS there are 10 cores dropped from 18 cores are available. As for the other cores were in under normal circumstances of that is below the standard (International Telecomunication Union) No. T-REC-G-199802-1 is 0.35 dB/km for wavelength 1310 nm and 0.25 dB/Km for 1550 nm, indicating that of all the links that have been built have good performance and under normal circumstances so that it can be used to operate.
