This project shows the design and simulation of a fiber optic link that joins the ends located between the cities from Valledupar and Popayán, choosing the best way to do it and through the simulation to discover which is the appropriate hardware for said solution, to be able to compensate for the needs of the network, this document will be divided into the following aspects: starting with the layout of the route between the municipalities from Valledupar and Popayán, continuing with the selection of both the wiring and the rest of the hardware necessary to establish said route in order to design and simulate the budget of energy and bandwidth so that it can be verified by simulation if the link meets the link quality.
