The overall structure of this cable consists of 3 functional units , 3 Filled element units and 3 out layers ,

The yellow functional unit with 12 fibers in the middle of it, and the fibers are filled in a protective TPE loose buffer tube , A layer of rat-proof spiral armored steel tape wrapping outside of the TPE tube, together with a layer of Kevlar yarn reinforce the tensile resistance of the cable, the outermost of the yellow unit is LSZH jacket ,the main function of the yellow unit is signal transmission ;                                                                  The red and black functional units have the same structure of inner 14AWG copper wire and outer OFCP(or custom PVC /LSZH/OFNP)jacket, the main function of the copper wire is conductive and grounding ;            To ensure the structural stability of the entire cable ,3 LSZH filled elements are placed inside the cable;            For outer 3 layers, including inner wrapping tape,middle kelvar yarn and outermost TPE (or custom OFCP/PVC /LSZH/OFNP) outer sheath , together with all above contents,completed to be a integrated cable.
