Twisted Pair
- It consist of two insulated copper wires arranged in a regular spiral patter where the wire pair acts as a single communication link. Twisting of the wires tend to decrease the interference e between adjacent pairs in a cable.
- The twisted pair cable offers between 2Mbps to 3Mbps.
- These cables are inexpensive
- It has a capacity of 1MHz
- Shielded twisted pair cable encases the signal carrying wires in a conducting shield as a means of reducing the potential for electromagnetic interference. Whereas a unshielded twisted cable does not rely on physical shielding but it instead relies on balancing and filtering techniques such as using media filters.
