| 摘要 |
<p>Proposed is an electric wave communication cable comprising a central core element formed from three pairs of twisted insulated conductors, each pair having electrical characteristics which make it suitable for the transmission of high frequency signals and having accommodated in the interstices of the pair a further pair of conductors having electrical characteristics which limit their effective use to the transmission of audio frequency signals, and nine pairs of twisted insulated conductors arranged about the central core element, each of the nine pairs having electrical characteristics which render it suitable for the transmission of high frequency signals.</p> |
