摘要： The present disclosure relates to a central tension line for an overhead power transmission cable having a damage detection function and an overhead power transmission cable comprising same, wherein it is possible to detect whether the central tension line is damaged before installing the overhead transmission cable on a pylon or before clamping for the installation of the overhead transmission cable, and after installing the overhead transmission cable on the pylon; and the central tension line has excellent tensile strength, thus having excellent sag properties preventing the wired overhead transmission cable from sagging, and has flexibility, thus improving wiring workability, while the central tension line suppresses corrosion and damage to a conductor wire disposed around the central tension line, and thus eliminates or minimizes an increase in resistance of the overhead transmission cable and the resultant reduction in transmission capacity, and enables the reduction of weight and manufacturing costs.

摘要： A multi-core optical fibre comprises a plurality of cores embedded in cladding. The cladding comprises a polymer. The cladding has an outer cross-sectional shape with an order of rotational symmetry of less than or equal to 4. By limiting the rotational symmetry of the multi-core optical fibre, rotational alignment of the cores with light sources/light detectors may be made easier. Also provided are optical cables and kits including the multi-core optical fibre, and a method of fabricating a multi-core polymer optical fibre.

摘要： A tapered fiber optoacoustic emitter includes a nanosecond laser configured to emit laser pulses and an optic fiber. The optic fiber includes a tip configured to guide the laser pulses. The tip has a coating including a diffusion layer and a thermal expansion layer, wherein the diffusion layer includes epoxy and zinc oxide nanoparticles configured to diffuse the light while restricting localized heating. The thermal expansion layer includes carbon nanotubes (CNTs) and Polydimethylsiloxane (PDMS) configured to convert the laser pulses to generate ultrasound. The frequency of the ultrasound is tuned with a thickness of the diffusion layer and a CNT concentration of the expansion layer.

The optical fiber cable (200, 300, 400) comprises one or more optical transmission elements (202, 302, 402) extending in a longitudinal direction surrounded by one or more coil elements (100). The one or more coil elements are a series of loops such that each loop (106) from the series of loops is physically connected to adjacent loops. The one or more coil elements are flexible in transverse direction and are substantially non-elongatable in the longitudinal direction. The one or more coil elements are fiber retaining element (102) such that subsequent loops (106) are made of a single continuous element and further comprises a pitch retaining element (104) connecting the subsequent loops of the fiber retaining element to preserve relative position of the subsequent loops.
