Tighter twisting in twisted pair cables enhances transmission rates by improving the coupling between the wires, which reduces electromagnetic (EM) radiation loss. This design minimizes energy escape along the cable's surface, allowing for higher frequencies to be transmitted over longer distances. Additionally, tighter twists contribute to better common mode rejection, further enhancing signal integrity. Overall, the twisting technique is crucial for optimizing performance in data transmission applications. Understanding these principles is essential for effective cable design and usage.
