Today, we find that companies providing services for HFC networks have greatly expanded their networks, the use of these assets is seen as the amplifier for distribution of their signals, as this is an active maintainer stable signal for transmission parameters, you do not have the documentation and information necessary for this asset has the reliability and stability to make it profitable . For this reason, this paper is to raise a number of routines to be applied in preventive maintenance. First, an approach to the installation of these assets is made, because this is the start to have and ensure good reliability since its installation depends on the proper functioning. A series of routine maintenance for amplifiers that are used in HFC networks is suggested that in order to optimize the resource in companies providing services through HFC networks. What you want with this proposal is that companies reduce their impacts no signal , flashes or degradation.
