Optical fiber can transfer data or information with high speed and a large <br /> <br /> bandwidth. Because of that, optical fibre can give a triple play service which <br /> <br /> includes home telephone service, internet service, and cable TV service. <br /> <br /> A network using optical fiber is called FTTx (fiber to the x). One of the FTTx <br /> <br /> architectures is FTTB (fiber to the building) which is an optical fiber network <br /> <br /> dedicated for high rise building (HRB). In the installment of optical fiber network, <br /> <br /> a thorough planning is needed. <br /> <br /> In this final project, a planning for an FTTB network will be deployed using <br /> <br /> Gigabit Passive Optical Network (GPON) technology. The planning is done by <br /> <br /> learning about the location and the site plan of the apartment that will be installed <br /> <br /> with an optical fiber network then choosing the right devices that will be used <br /> <br /> along with the needed amount. The planning will be continued by making the <br /> <br /> appropriate network configuration design. The last step is making the necessary <br /> <br /> calculation and analysis of the network capacity, the link power budget, and the <br /> <br /> rise time budget in order to find whether the network is up to the standard and <br /> <br /> ready to be used. <br /> <br /> The network uses 25 ODP devices, 141 ONT devices, and 59 spares. The <br /> <br /> maximum capacity of the network can be used to serve 145 users/core with bit <br /> <br /> rate up to 1.659 Gbps. The power margin is 1.748 dB for upstream and 1.927 for <br /> <br /> downstream. The total loss including its tolerance factor is 25.252 dB for <br /> <br /> upstream and 25.073 dB for downstream. The rise time budget is 0.25 ns for <br /> <br /> upstream and 0.2522 ns for downstream. <br /> <br /> Network planning has fulfilled the quality standard with link power budget below <br /> <br /> -28 dBm and power margin above 0 (zero). Also, the rise time budget doesn’t <br /> <br /> exceed 70% of one bit periode of NRZ. <br />
