What practice should be followed to ensure compliance with standard requirements for horizontal cabling in a structured cabling system?

Using copper cabling in a structured cabling system, it is critical to adhere to the standard practice that the cable length does not exceed 90 meters. This 90-meter limit is defined to maintain performance standards for Category 5e and Category 6 cabling. The rationale behind this requirement is to minimize signal loss and attenuation, ensuring that the network operates efficiently and reliably. After the 90-meter mark, degradation in the signal quality can result, which can lead to reduced network performance and increased errors in data transmission.

Additionally, the total length of a horizontal cabling run—including both the permanent and the patch cords—should not exceed 100 meters according to telecommunication standards. However, even within this total length, keeping the permanent connection to 90 meters is crucial for ensuring that the system remains compliant with the standards and performs optimally.

The other practices mentioned, such as exceeding cable lengths or using only fiber optic cabling, do not align with these standards and can lead to compliance issues and network performance problems. Also, while having multiple Intermediate Distribution Frames (IDFs) on a single floor can be beneficial for certain network setups, it does not directly relate to compliance with the standard requirements for horizontal cabling length. So, the best
