What is the method used for grounding on a shielded cable?

The method for grounding a shielded cable involves grounding one end of the shield. This approach serves to minimize the risk of ground loops and potential differences that could lead to interference or noise in the signal transmission. When only one end is grounded, it helps to direct any induced currents in the shield to ground, while preventing the creation of ground loops that could adversely affect the performance of the cabling system.

Grounding both ends of the shield can introduce issues related to ground potential differences. If one end of the shield were to be grounded at a different potential than the other, this could result in unwanted current flow along the shield, producing interference. Thus, grounding just one end is considered the best practice for maintaining signal integrity and ensuring proper performance of the cable system.

The other options suggest methods that either do not appropriately address the grounding needs or introduce complexities that could cause performance issues. Hence, the method of grounding one end of the shield is the most effective and widely endorsed practice in the implementation of shielded cabling systems.
