Why is it important to observe proper cable segregation?

Observing proper cable segregation is crucial primarily to prevent interference from power cables affecting data transmission. When data cables are installed alongside power cables, electromagnetic interference (EMI) can occur, leading to signal degradation, increased error rates, and unreliable network performance. By maintaining segregation, technicians help ensure that data signals remain clear and intact, contributing to the overall reliability and effectiveness of the network.

This practice also aligns with industry standards and guidelines, which recommend specific distances and separation methods between different cable types to mitigate interference risks. While other considerations like compliance with zoning laws, aesthetic appeal, and cable management are important, they do not directly address the critical technical requirement of maintaining signal integrity by preventing interference.
