For effective termination of data cables, how much untwisting is acceptable?

For effective termination of data cables, the guideline typically recommends not exceeding 12.7mm of untwisting of the pairs. This limit is crucial because maintaining the twist of the data pairs is important for reducing crosstalk and ensuring the integrity of the signal. When the pairs are untwisted beyond this length, it can introduce interference and degrade the performance of the cable, which can lead to issues such as data loss or reduced transmission speeds.

While some options suggest greater lengths of untwisting, adhering to the standard of not exceeding 12.7mm ensures that the cable maintains its electrical characteristics and performs optimally. This helps in achieving the necessary performance standards outlined in industry specifications, ensuring reliable communications within the network.
