Abstract
The embodiments of the present invention relate to optical communication technologies, and provide a method, an apparatus, and a unit for detecting a fault of a submarine device. The apparatus includes: a pair of optical couplers that are respectively set on two optical cables for transmitting optical signals in opposite direction and are configured to receive or send optical detection signals through the optical cables, where: the two optical couplers are connected through an optical fiber that transmits an optical detection signal, and a photosensitive component is set on the optical fiber and is configured to adjust an optical parameter of the optical detection signal by perceiving change of an ambient environment state parameter when a fault occurs. The embodiments of the present invention bring benefits of detecting whether a target submarine device is faulty, and locating a cause for the fault of the submarine device accurately.
