The screen of the STP to make it more effective requires a configuration of interconnection with Earth (with continuity to the terminal), with the STP is commonly used connectors RJ49. However it is more expensive and requires more setup time. The level of protection of the STP to external shocks is greater than the one offered by UTP.
In this case, each pair is covered by a conductive mesh which acts as a screen against interferences and electrical noise. But at high speeds it can be vulnerable to electromagnetic interference of the environment. It is undoubtedly that so far has been better accepted, accessibility cost and easy installation. The connector most commonly used in this type of cable is the RJ45, similar to the RJ11 used in phones (but a little large), but they can also be used other (RJ11, DB25, DB11, among others), depending on the network adapter.
Twisted pair cable is the most used, it does not possess any additional protection to the PVC coated and it has 100 Ohm impedance. This wire is only used in special circumstances and seldom to use.What is UTP, FTP and STP Copper Network Cable? UTP cable (Unshielded Twisted Pair) The price of this wire is usually twice that of UTP. The disadvantage is that this wire is very soft and expensive. The structure of this wire is based on the aluminum foil of FTP/STP, plus a layer of tin-plated copper braided mesh, the outside of which is PVC.Due to the extra layer of tin-plated copper wire mesh, the external magnetic field can be greatly reduced, and the signal interference can also reduce the attenuation of internal signals and increase the tension of cables. The market is less popular.SFTP: double shielded network wire.
The former is a broad name and the latter is a narrow term.In fact, the current blocking network line is the aluminum foil shielding network wire, so STP and FTP are actually the same.Ĭompared to UTP, FTP/STP is just a layer of aluminum foil outside the core to reduce the attenuation of the signal.
