ABSTRACT:
Provided is a method of constructing a normal joint structure for connecting superconducting cables having a cable core and an optical fiber arranged along the cable core. With the method, which includes the steps of: pulling out an optical fiber from the end of each of two superconducting cables to be connected together and splicing the optical fibers thus pulled out; returning the excess length of the pulled-out optical fiber to a superconducting cable side upon the completion of splicing; and connecting the cable cores, it is possible to reduce the quantity of optical fiber housed in a joint box, and accordingly to downsize the joint box.
