To minimize electromagnetic interference (EMI), how many inches should be maintained between power cables and unshielded communications cables?

Maintaining a distance of 24 inches between power cables and unshielded communications cables is essential for minimizing electromagnetic interference (EMI). EMI can disrupt the signal integrity of communication lines, leading to data loss or degradation in performance. The 24-inch separation helps ensure that the electromagnetic fields generated by the power cables do not interfere with the operation of the communications cables. This distance is based on industry standards and best practices that have been established to promote reliable communication systems. By adhering to this guideline, installers can help prevent issues related to crosstalk and noise, ultimately resulting in a more effective and stable cabling infrastructure.
