Abstract

See full text

A cable (10) includes a cable body (11) that is formed from a plurality of wires (14) that are integrally bundled; and a pair of sockets (12) to which both end portions of the cable body (11) is separately affixed; at least one of the plurality of wires (14) being a fiber-containing wire (16), which is formed by an optical fiber (17) that extends in a cable length direction (D) and that is protected by a protective tube (18); wherein the optical fiber (17) protrudes from the protective tube (18), in the cable length direction, further outside than the socket (12); and each of the pair of sockets (12) is provided with a spool (30) that removably holds the optical fiber (17) and imparts an initial tensile strain to the optical fiber (17).
