Question: 1 / 400

What is the maximum length for copper cabling according to standards?

50m

70m

90m

100m

The maximum length for copper cabling, particularly for twisted pair cabling like Category 5e, Category 6, or Category 6a, is defined by industry standards as 100 meters. This standard includes 90 meters of horizontal cabling plus an additional 10 meters for the patch cords. This length is crucial because it ensures the proper performance and integrity of the copper cabling in networking environments, maintaining signal strength and minimizing interference.

Understanding this limit is essential for network design and implementation, as exceeding this maximum length can lead to increased attenuation and signal degradation, potentially resulting in system errors, reduced performance, and connectivity issues. Thus, adhering to the 100-meter maximum length is vital for maintaining an efficient and reliable data center network infrastructure.
