The photoelectric signal conversion and transmission device includes a photoelectric signal module and a fiber joint, matched and coupled together. A circuit board of the photoelectric signal module includes one or more connection bases. Light emission elements, light reception elements, and amplifiers are configured on a first coupling face of the connection based, and electrically connected by first and second wires.

In an optical network having a terrestrial terminal and an open cable interface (OCI) connecting a submarine cable to a terrestrial cable, the OCI may include a filter positioned on an optical path between the terrestrial cable and the submarine cable and configured to pass first communication signals of a first frequency band, and filter out secondary signals of a second frequency band that does not overlap with the first frequency band. The secondary signals may be looped back to the terrestrial terminal. The terrestrial terminal may detect the looped back secondary signals, and in response, determine the presence of the OCI and that the supervisory signals were rerouted by the OCI.
