Abstract: The present invention is an improved cable for use in accurate signal transmission where limited space may be available for cable termination to a backplane or other interface. The cable of the present invention employs highly effective insulation materials of whatever diameter may be required along the majority of its length, but reduces the diameter of such materials at connective ends of the cable. As a result, very accurate, high speed signal transmission is provided while allowing high density cable attachment at input/output ports. Further, the present invention provides an improved method for rapidly and accurately constructing a cable with changed diameter along its length.

Abstract: An improved low noise electrical signal transmission cable is disclosed. The cable employs an insulative layer of expanded polytetrafluoroethylene (PTFE) which is bonded in fixed relative position with a surrounding shield layer through use of an adhesive, such as fluorinated ethylenepropylene (FEP) or perfluoroalkoxy polymer (PFA). The bonding process reduces the separation of layers which can sometimes occur with expanded PTFE insulative cables and avoids the generation of unwanted triboelectric signals that can result from such separation.
