What is the main issue if ingress or impulse noise is high enough in a network?

The main issue with high levels of ingress or impulse noise in a network is that it can cause data loss due to signal distortion. Ingress noise refers to unwanted signals entering a communication channel, while impulse noise is characterized by sudden increases in voltage or current. When these types of noise are high, they disrupt the integrity of the transmitted signals, leading to errors in data interpretation. This distortion can corrupt the original data being sent, causing the receiver to misinterpret the information or even lose it altogether.

Although considerations such as bandwidth, network reliability, and laser clipping are important, the direct impact of ingress or impulse noise manifests most critically through data transmission errors induced by signal distortion. If the noise level interferes significantly with the data signal, it can lead to increased erroneous data packets, requiring retransmissions and ultimately affecting the effectiveness of communication within the network.
