Cable types include Adss cable (Alexia) non metallic strength member outdoor optic with stray wire, direct burial or fiber optic cable ADSS, as well as OPGW cables that are used in overhead transmission lines and have an optical fiber loop for protection from lightning without creating radio interference. ONT fitting sets can be made to order depending on your demand which can include one set of octopus clamps (5mm, 5mm, 6mm), two sets of cable binding bands (5.5mm, 6mm). Beside the functions of transmitting data, voice for a few kilometers and video for even shorter distances, the main functions of fiber-optic cables are for telecommunication. They are superior to traditional copper cables in terms of technological features such as high bandwidth and low attenuation. With core, cladding and coating making up a typical cable, the core is that part which actually performs optical transmission. China's fiber cables have single-mode and multi-mode types that can be used for internet connections or as transmission media within data centers. Their quality of resistance to interference, long life span likely ensure that all types will maintain good correspondence in practice over the years.
