What is the effect of electromagnetic interference on network cabling?

Electromagnetic interference (EMI) can have several detrimental effects on network cabling and communication signals. It disrupts the electrical signals being transmitted through the cabling, leading to various issues that can significantly hinder network performance.

When EMI is present, it can introduce noise into the data signals, which can result in data loss, as the corrupted signals may not be correctly interpreted by network devices. This loss of data can necessitate retransmissions, which slows down overall network performance. Consequently, devices may experience latency or degraded performance as they struggle to maintain a stable connection amid the interference.

Understanding the negative consequences of EMI is crucial for designing robust networks. Proper shielding and the use of twisted pair cables, which are designed to minimize EMI effects, are effective strategies to mitigate these issues and ensure reliable communications.
