摘要： The present invention relates to a method for mid-span branching of optical fiber cable which makes the mid-span branching possible without excess length of the optical fiber cable by forming main branching part and sub branching part for branched cores to be taken out from an existing main cable. It is an object of the present invention to provide a method for mid-span branching that provides marginal length of the existing main cable from which the branch cable branches off without the excess length of cables. To accomplish the above object of the present invention, there is provided a method for mid-span branching of optical fiber cable, comprising the steps of: setting an existing main cable and a branch cable; unsheathing main branched part and sub branched part of the main cable with preserved part; choosing and cutting branched cores with preserved cores remaining uncut; connecting the first branched cores to first branching cores to make temporary connection; pulling out the temporary connection to the sub branched part through the preserved part; and splicing the first branched cores and the first branching cores at the sub branched part, and splicing the second branched cores and second branching cores at the main branching part, second branching cores in the branch cable.
