Abstract
A patch high-speed cable for LAN applications having a jacket surrounding at least two twisted-pair insulated cables. Each of the twisted-pair cables have at least one tin sealed stranded tinned metal conductor. The tin sealed stranded tinned metal conductor has 7 or 19 tinned metal strands and a size of 24 or 26 AWG. Each of the tinned metal strands has a tin coating of 20 to 90 micro-inches. The insulation on the metal conductor has a thickness of about 0.007 to about 0.011 inches and a dielectric constant of about 2.2-2.5 and a dissipation factor of 0.0001 to 0.001. The twisted pair cable has an attenuation dB/100 ft. increase of less than 1.0 and preferably less than 0.5 when subjected, as an unterminated twisted pair cable over a 35 day period, to 100 MHz per 100 ft. and ambient air having a humidity of 40 to 80%.
