The main difference between shielded and unshielded ethernet cables is their ability to reduce (or eliminate) the effects of electromagnetic interference (EMI) on the cable. If ethernet cables are exposed to EMI while transferring data, it can disrupt the connection and greatly reduce the performance of the cable. Shielded ethernet cables were created to prevent just that. Shielded ethernet cables have a foil layer that wraps around the 4 pairs of twisted copper wires inside an ethernet cable. In addition, there’s a wire that runs along the length of the ethernet cable on the inside of the foil. This wire is called a drain wire. The purpose of the foil and drain wire is to ground any EMI in the environment around the ethernet cable. This effectively reduces the impact of EMI coming from the area around the ethernet cable. Unshielded ethernet cables do not have this protection, and as a result, they shouldn’t be used in environments with a lot of EMI. The good news here is that most homes and offices do not normally have many sources of EMI, so in most cases, unshielded ethernet cables will work just fine. Conversely, shielded ethernet cables should be used in environments with heavy machinery, electrical wires providing alternating current, microwaves, and electric motors.
