Proper preparation for cable termination not only improves the quality of the job but also decreases the amount of time required for termination. 150 ohm shielded twisted-pair copper cable (STP-A).100 ohm screened twisted-pair copper cable (ScTP).100 ohm unshielded twisted-pair copper cable (UTP).The following types of cable are currently recognized by the ANSI/TIA/EIA-568-A standard for use in premises cabling: You must ensure you've selected the proper crimp connector for your specific cable. Screw-type terminal faceplates commonly used in voice applications are not recommended by ANSI/TIA/EIA-568-A for UTP terminations.Ī crimp-style connector for copper and coaxial cable is dependent upon the shape and diameter of the cable. This ensures a solid connection between the copper conductor and terminating clip. During termination, you press the cable between two edges of a metal clip, which displaces the insulation and exposes the copper conductor. Punch-down connections remove or displace the conductor's insulation as it is seated in the connector. Commonly called punch-down connections, these connections require the use of a small punch-down tool to properly secure the cable to terminal block. Insulation Displacement Connection (IDC) termination is the recommended method of copper termination recognized by ANSI/TIA/EIA-568-A for UTP cable terminations. Proper cable termination practices are vital for the complete and accurate transfer of both analog and digital information signals.
