Abstract
Certain embodiments herein relate to reducing impairments in signals transmitted over a service provider network. A selective filtering device may be placed at various locations in the service provider network to reduce the noise. For example, the devices may be located in, coupled to, or otherwise associated with a tap, an optical node, an amplifier, or other location in the service provider network that may be upstream from user devices at customer premises locations. The selective filtering device may be selective in the way that it may use various types of filtering techniques to eliminate or reduce the noise in a signal. Such techniques may be based on the power densities of carriers and noise in the signal, as well as information associated with scheduled communications in the service provider network.
