Abstract

PURPOSE:To exactly and easily attach and detach plural optical cables by using the magnetic forces of superconducting coils for each of the respective optical cable pairs for attaching and detaching the optical cables and providing means which are capable of turning on and off the magnetic forces individually. CONSTITUTION:Electric current continues to flow in the superconducting coils to maintain the magnetic forces of superconducting electromagnets 6 after the current is first applied by turning on of a switch 12 from a power supply 11 to the superconducting coils in a superconducting state maintained in such a temp. range at which electric resistance is decreased to zero. The superconducting electromagnet 6 attracts magnetic force sensitive parts 5 at the front ends of a pair of the optical cables 4 to bring the respective ends of the two optical cables 4 into contact with each other when the optical cables 4 are inserted into this state into guide parts 3 respectively from both directions. The two optical cables 4 are thus connected. The superconducting coil loses the superconducting state when the coil is heated to the prescribed temp. or above by turning on the heat source of a temp. control part 13. The optical cables 4 can then be detached from the guide parts 3. The optical cables are thereby easily and exactly attached and detached to and from the guide parts.
