SUMMARY

Tighter twisting in twisted pair cables significantly enhances the supported transmission rate due to improved electromagnetic coupling between the wires. This design minimizes electromagnetic radiation loss, allowing higher frequencies to be transmitted over longer distances. The common mode rejection capability is also improved with tighter twists, further enhancing signal integrity. For detailed information, refer to the Twisted Pair Wikipedia page.

Why is that in twisted pair cable, the tighter the twisting, the higher the supported transmission rate?


Thankyou
 
Engineering news on Phys.org
The tighter the twist, the better the coupling between the two wires, the less the EM escape out along the surface so less energy is lost from radiation along the way so higher frequencies can be carry for longer distance.
 
I totally forgot the common mode rejection part! Sorry.
