Core Management Methods and Power Link Budget Analysis for New Optical Fiber Expansion

The need for data communication continues to increase every year. Changes in the transmission of copper cables to optical cables are continuously being made to meet the public's need for the internet. Various methods have emerged to accommodate the needs for large capacities and high speeds. In some areas where the fiber optic network has not been reached, the construction of a new network is carried out to meet the public's need for internet. In-network development, of course, there are obstacles encountered, such as losses during connection. The amount of cable buildup when expanding due to repeated cable pulls in the same area. From these conditions, a solution is offered by optimizing the use of existing cables. By applying the concept of the Fiber to The Home (FTTH) network using Gigabit Passive Optical Network (GPON) technology, a1:4 splitter. Using a power link budget to obtain attenuation magnitude, core determination using core management methods, and simulation using optisystem. This process results in the calculation of the power budget of-19.21 dBm, -19.22 dBm, and -22.72 dBm. The cores used are based on the results of the management core, namely blue and brown cores. So it is stated that the design of a new area expansion is feasible to be implemented in the field and of course a solution to reduce the build-up when a new optical network will be expanded.
