![]() ![]() Several manufacturers provide rack-mountable and wall-mountable IDC termination hardware that can house multiple termination blocks. These comprise the majority of the market however, other devices are available. There are four basic types of IDC termination blocks used in the termination of horizontal and backbone copper cabling: the 66-type, 110-type, BIXTM, and LSA. The minimum bend radius for UTP and ScTP cable is four times the cable diameter, while optical fiber cable is 10 times the diameter.Ĭopper IDC (punch-down) termination. This protects the integrity of the cable. Because UTP and ScTP cable are protected from crosstalk and immunity from EMI through the cable's pair twist and lay configuration, make sure you maintain the minimum bend radius of the cable.They also provide support for additional cable, you may need to install as a result of a move, add, or change. All of these products are designed to properly support the in-place cables and relieve tension. There are several different types and styles of cable management hardware.Use the proper cable management hardware. The tie wraps or hook and loop straps should be evenly spaced throughout the dressed length. Use tie wraps or hook and loop straps to secure the cables.Pay attention to ensure the new labeling matches the old labeling. After determining the proper amount of slack necessary, you should relabel the cables and cut them to uniform lengths. Cables may be entering the wiring closet from multiple directions, which frequently results in cables of many different lengths.Next, smooth them with your hand until they form a neat, orderly bundle. Dress the cable by ensuring all cables are parallel to each other.On the front side of the rack, dedicate a minimum of one rack space (unit) of cable management for every two rack spaces (unit) of patch panels.First, prepare the cable for termination by bringing all cables into a bundle.Modular furniture requires a different variety of outlets than drywall offices, so make sure you specify the proper product type and manufacturer.įorm and dress cable at the rear of the panel. Verify the right products are on hand for the application.In equipment rooms, ensure you install blocks and/or panels in accordance with the designer's layout. For work area terminations, make sure all cables are available and properly labeled at the wall outlet locations.Only the T568A and T568B wiring schemes are compliant with the ANSI/TIA/EIA-568-A standard. With copper IDC terminations, there are three predominant wiring schemes: T568A, T568B, and Universal Service Order Code (USOC). If you use incompatible parts for terminating, drastic results may occur. Cable connection is not complete until all terminations are properly identified and labeled. In determining this length, you should leave enough slack in case you need to reterminate for any reason. You must also take into account the length of cable needed to reach the termination. Place the cable to be terminated in close proximity to the point of termination, and properly identify it to make sure it's terminated in the correct position.įorming and dressing the cable involves properly aligning and positioning the cables in a neat and orderly manner for termination. ![]() First, organize the cable by destination. 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. ![]()
