Claims
- 1. A telecommunications cable having improved insertion loss characteristics made in accordance with the method comprising the steps of forming a plurality of wire units by advancing groups of twisted wire pairs or quads through twisting stations wherein each group is alternately twisted in clockwise and counterclockwise rotary directions with both the frequency and amplitude of the twisting being modulated; stranding the plurality of units so formed together into a cable core; and forming a conductive sheath around the core.
- 2. A telecommunications cable made in accordance with the method comprising the steps of forming a plurality of wire units by advancing groups of twisted wire pairs or quads through twister head faceplates while oscillating each faceplate with both the frequency and amplitude of each faceplate oscillation being continuously modulated; stranding the plurality of units so formed together into a cable core; and forming a conductive sheath around the core.
