Designed specifically, for data transfer from headline sonar to bridge . 10 A co-axial data transfer cable with central copper conductor and screen enclosed in a DynIce Dux rope. Specially designed for data transfer from trawl headline sonars where high loads are on the cable while signal is sent or data retrieved. 11 The cable is also very suitable for deep sea research vessels using drum winches. The production process is unique and patented. The construction is based on copper centre conductor with dense screen of copper 12 filaments to protect from electromagnetic waves. The data cable can also be used as high strength 13 single phase conductor. 14 15 16 17 18 19 20 DynIce Optical Data is patent protected.
