Abstract
Light signal transmitter units-to-n of a transmitter deviceperform optical communication with a receiver devicevia optical fiber cables-to-n of an optical interface cable. A connection detection unitdetects whether connection to the receiver device is established via the optical interface cable, and a visible light source control unitcauses a visible light source unitto emit visible light that can identify by an attribute a connection relationship with the receiver device connected via the optical interface cable, only when the connection to the receiver deviceis not detected, and causes visible light superposition units-to-n to superpose the visible light on the cable. The receiver device also superposes on the cable the visible light that can identify by the attribute the connection relationship with the transmitter device connected via the optical interface cable, only when the connection to the transmitter deviceis not established, in the same way as the transmitter device. The connection between the optical communication devices can be correctly and easily performed by using the optical transmission path.
