1. An optical fiber cable comprising:
an optical fiber through which laser light output from a light source propagates;
a cable jacket that comprises an inner tube and an outer tube covering the inner tube;
a first open detection line and a second open detection line;
a first breaking detection line and a second breaking detection line; and
an optical connector disposed at a first end of the optical fiber cable, wherein
a first end of the first open detection line and a first end of the second open detection line are disposed inside the optical connector and are not electrically connected to each other inside the optical connector,
a first end of the first breaking detection line and a first end of the second breaking detection line are disposed inside the optical connector and are electrically connected to each other inside the optical connector,
the optical fiber is disposed in one of a first region and a second region, wherein the first region is inside the inner tube and the second region is between an outer surface of the inner tube and an inner surface of the outer tube, and
