Data/ PCM/ Instrument/ Signalling Transmission Cable is used for signal transmission in electronic applications and data communication. The Signalling Transmission Cable is available in both shielded and unshielded forms to suit specific application requirements. The Signalling Transmission Cable uses 99. 97% pure solid electrolytic grade copper for `o` db loss for conductivity, free data transmission. The Data/ PCM/ Instrument/ Signalling Transmission Cable is used for faster signal speeds over longer distance without losses of signal.
