A new deep-sea coaxial cable

Development work during the last five years has resulted in a new type of deep-sea coaxial cable which is cheaper and lighter than the present conventional type. It has no external armour and is virtually free from any tendency to kink. Ocean trials are about to take place, and, if successful, the armoured type of deep-sea telephone cable will probably soon become obsolescent.
