Solange Émile When installing a Cat5 cable network, there are two main wiring diagrams that can be used: A and B. Both diagrams use the same four pairs of wires, but the order of the pairs is different. The A diagram is the most common and is used in most homes and businesses. The B diagram is less common and is typically used in industrial settings.
The main difference between the two diagrams is the way that the pairs of wires are twisted together. In the A diagram, the pairs are twisted together in a clockwise direction. In the B diagram, the pairs are twisted together in a counter-clockwise direction. This difference in twisting direction helps to reduce crosstalk between the pairs of wires, which can improve the performance of the network.
When choosing which wiring diagram to use, it is important to consider the specific needs of the network. If the network is going to be used for high-speed data transmission, then the A diagram is the best choice. If the network is going to be used for low-speed data transmission, then the B diagram can be used.
