Stp Type 1 Cable

Shielded twisted pair stp cabling is more expensive than unshielded twisted pair utp cabling.

Stp type 1 cable.

An early example of shielded twisted pair was ibm stp a which is a two pair 150 ohm s ftp cable defined in 1985 by the ibm cabling system specifications and used with token ring or fddi networks. Some stp cablings make use of a thick copper braided shield which makes the cable thicker heavier and in turn much more difficult for installation as compared to the utp cables. It supports easy connectorization and is moderately flexible. Type 1 is used to connect terminals and distribution panels or to connect between different wiring closets that are located in the same building.

Utp and stp are the types of twisted pair cable where utp is the unshielded type whereas stp is shielded for doing so metal foil or braided mesh is used. The maximum cabling distance is 101 meters 331 feet. This was the basic cable for the ibm cabling system a structured cabling system that ibm hoped would be widely adopted. Use sf utp cable when you need protection from low and high frequency noise interference.

Type 1 uses two stps of solid core 22 awg wire for long high data grade transmissions within the building s walls.

Cabling is generally ibm type 1 a heavy two pair 150 ohm shielded twisted pair cable.

The other usual stp cables often called foil twisted pair cables or screened twisted pair cables make use of just a thinner outer foil shield. Key differences between utp and stp cables. Utp reduces the crosstalk and noise as compared to the parallel arrangement of the wires but not at great extent. It has an impedance of 150 ohms has a maximum length of 90 meters and is used primarily in networking environments with a high amount of emi due to motors air conditioners power lines or other noisy electrical components.
