Description

technical field [0001] The invention relates to the field of optical cable splicing, in particular to a multi-core optical cable splicing relay value testing device and testing method. Background technique [0002] For indoor multi-core optical cables, optical cable digging is a very common construction technology. Optical cable digging is also called skylight opening, that is, the optical cable is cut longitudinally with special tools to expose the core, and several fibers are connected to the core of the branch cable. The fiber core is not damaged, thereby avoiding unnecessary shearing of a large number of fibers. [0003] Indoor multi-core optical cables generally use low-smoke halogen-free flame-retardant polyolefin as the outer sheath and the protective layer of the subunit, and add aramid fiber as the strengthening element, which has low tensile strength and poor protective layer. When the number of optical cable cores is large, the internal subunits including the ara...
