Signal transmitting cable

摘要

A cable ( 302 ) has (8) fibres ( 304 ) are encapsulated by a UV curable layer ( 306 ) having a diameter of approximately (1010) microns, and (16) outer fibres ( 316 ) arranged in a circular formation around the inner fibres ( 304 ). The optical fibres ( 304 ) are held in position by means of the UV curable layer ( 306 ) so that the UV curable material of the layer ( 306 ) does not penetrate into the gaps between the optical fibres ( 304 ) and the outermost optical fibres ( 304 ) are restrained by the layer from moving axially. It is found that such an arrangement provides surprisingly favourable bending properties, making the cable particularly suitable for installation in a tube by means of blowing.
