Technological developments in the telecommunications sector have experienced a very rapid development, in the current digital era the need for information is very important in the form of voice, data, images and video. So to meet such a large need, it is necessary to have a network quality that has good capability to support network performance. Fiber To The Home (FTTH) network is a network that uses optical fiber as a medium for transmitting data, so as to provide excellent data transmission performance, Fiber to the home is integrated with Gigabit Passive Optical Network (GPON). Central Office (STO) Pakem, Sleman, Yogyakarta is a ftth service provider of PT. Telkom to serve the Pakem area and its surroundings. In this final project, an analysis of ftth network performance in STO Pakem with Link Power Budget, Rise Time Budget, Signal Noise to Ratio and Bit Rate Error parameters is applied. Where measurements were taken on four customer samples from STO Pakem. It is known that almost all of these network systems are reliable and in accordance with existing standards, except for customer systems for three and four systems for Signal Noise to Ratio and Bit Rate Error parameters, which are still below the standards set by ITU.
