Abstract
In communication cable of high capacity according to present invention, conductor of diameter d is coated by insulation material to form wire of diameter D, plural number of said wire are twisted by pitch p to form pairs, plural number of said pairs are twisted by collective pitch P, and said communication cable of high capacity comprise sheath wrapping said pairs, and impedance (Z) of said wire is from 90 to 110, and, diameter (d) of said conductor is from 0.53 mm to 0.65 mm, and diameter (D) of wire is from 0.9 mm to 1.1 mm, and said pitch (p) is from 8 mm to 25 mm, and said collective pitch (P) is from 40 mm to 150 mm, and relative ratio of diameter of wires to diameter of conductor D/d is from 1.625 to 1.835. And, by impedance matching between equipment for data transmission, return loss of cable can be minimized, so high speed data transmission can be made.
