Which two factors may interfere with the copper cabling and result in signal distortion and data corruption?
There are several factors that can interfere with copper cabling and lead to signal distortion and data corruption. Two of the most common factors are:
1. Electromagnetic Interference (EMI): EMI refers to the electromagnetic radiation emitted by various sources such as power lines, fluorescent lights, motors, and other electronic devices. When copper cabling is exposed to EMI, it can pick up these electromagnetic signals and cause interference. This interference can disrupt the normal flow of data and result in signal distortions or data corruption.
To mitigate the effects of EMI, shielded twisted pair (STP) cables are often used. These cables have a metallic shield around the conductors, which helps to reduce the impact of external electromagnetic radiation.
2. Crosstalk: Crosstalk occurs when the signals on adjacent copper cables interfere with each other. This interference can occur due to electromagnetic coupling between the cables. When data signals from one cable induce unwanted signals in an adjacent cable, it can lead to signal distortion and data corruption.
To minimize crosstalk, twisted pair cables are commonly used. Twisted pair cables have pairs of insulated copper wires twisted together, which helps to cancel out the interference between adjacent pairs.
Additionally, network devices such as switches and routers often employ techniques like error correction and retransmission to handle signal distortion and data corruption caused by these factors.
