What is the major advantage of shielded twisted pair (STP) over unshielded twisted pair (UTP)?
Answer: – Shielded twisted pair (STP) and unshielded twisted pair (UTP) differentiated physically by Littlemore than a conducting shielded, shielded twisted pair cables are unshielded twisted pair cables nonetheless have different advantage, disadvantage and best applications.
Both shielded and unshielded twisted pair has interference connecting capabilities. However the way that each one is designed to cancel the interference is different interference caused by power lines, radar systems or other high power electromagnetic signals, called noise, can causes an imbalance in the current flowing through the shield conductors of the cables which interference with the signal. Shielded twisted pair cable have a conducting shielded made of metallic for encasing the twisted wire pairs, which blocks the electromagnetic interference allowing it to carry data at faster rate of speed rather than unshielded twisted pair however, they have several disadvantages STP cables work by attracting interference to the shield them running it off into a grounded cable. It the cable is improperly grounded, then the noise conceding capabilities are severely compromised additionally, STP cable are bigger than UTP cable, and are more expensive. Finally they are more fragile than UTP cables, as the shielded must be kept intact in order for them to work properly the best use for STP cable are in industrial setting with high amounts of electromagnetic interference, such as a factory with large electronic equipment, where they can be properly installed and maintained.
Unshielded twisted pair cables are the moll commonly used cables for Ethernet connections and we have a number of advantages. They rely cancellation affected caused by the twisting of the wire pairs to handle noise, which is over than enough for most domestic uses. They are also similar than shielded twisted pair (STP) cables, which makes them easier to install, particularly in bulk or in narrow spaces. They are easier to install than STP and so not require the presence of a grounding cable. UTP cables are also cheaper than STP cables, and do not require as much maintenance, since they do not rely on an outer shield, and can transmit data as fast as STP cables. However, they are more prone to noise than property installed and maintained STP cables. They are best uses for domestic and office Ethernet connections, and in any area where there is not a high degree of electromagnetic interference while both STP and UTP cables have their advantage and disadvantage, when installed are maintained properly in a situation of appropriate to their uses, both work properly fine.
