7. An optical cable laying construction set for being assembled at a construction site, comprising:
an optical cable including a refractive index distribution-type plastic optical fiber and a cable jacket;
a first plug including a first connecting portion and a first electric connector, and having a configuration for converting an electric signal into an optical signal, the first connecting portion being connectable to the plastic optical fiber, the first electric connector being connectable to an external device;
a second plug including a second connecting portion and second electric connector, and having a configuration for converting an optical signal into an electric signal, the second connecting portion being connectable to the plastic optical fiber, the second electric connector being connectable to an external device; and
a first optical connector separate from the first plug and from the optical cable, which is applied to the optical cable, and which covers the plastic optical fiber of the optical cable, and upon insertion of the optical cable into the first plug, connects the plastic optical fiber to the first connecting portion of the first plug.
