Technological advances in the cable TV network, allow the achievement of higher transfer rates, however with a limited spectrum, it is necessary to optimize the network, increasing its density, consequently reducing the space for noise. Understand the origin of this phenomenon is of paramount significance, in order to give the most appropriate approach, and also ascertain the process necessary to maintain a quality standard in services. Therefore, the issue will be discussed, what comes to be an HFC network (Hybrid Fiber Coax), its origin and initial disposition and after the emerging of the hybrid network, emphasizing the part of the coaxial network, because it is the one that most wear out from the noise effects. Then, the main types of noise will be mentioned, along with the graph and its characteristics. For this purpose, a field research was fulfilled to understand how the process of treating noise in the network is applied, with some practices and results observed being presented at the end.
