Patent number: 4822956Abstract: Electro-static discharge is a problem with high-speed data even when using coaxial cables. Primarily, this problem arises at the terminal ends of the circuit where connections are made using separate coaxial cables for connecting to various pieces of equipment thereby allowing voltages to be induced differently in each such cable. This problem can be overcome by combining a portion of each cable such that the shield around each signal carrying wire remains intact while also being solidly in contact with the shield from the other wire. The cable is constructed by removing the outer insulation from a section of two single coaxial cables, electrically connecting together the exposed shields of each cable at both ends of the exposed section and reinsulating the abutted cables so that the shields remain in contact along their entire length.Type: GrantFiled: August 11, 1986Date of Patent: April 18, 1989Assignees: American Telephone and Telegraph Company, AT&T Information Systems Inc.Inventor: Edmund N.
