Pair-to-pair capacitance unbalance.
(2) Pair-to-pair capacitance unbalance. The capacitance unbalance as measured on the completed cable shall not exceed 45.3 picofarad/kilometer (pF/km) (25 picofarad/1000 ft (pF/1000 ft)) rms when tested in accordance with ASTM D 456690 at a frequency of 1.00.1 kHz and a temperature of 233 C.
