This junction device is inserted into a power feed line and a transmission line connecting first and second trunk stations and a branch station, and includes a switching means for controlling a switch so as to connect the transmission line between the branch station and the first or second trunk station when a current detection means detects that there is no longer current flowing through the power feed line between a junction unit and the branch station and when a first optical signal detection means detects an optical signal in the transmission line connecting the junction unit and the branch station."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Junction device, and undersea cable system","description":"Provided are a junction device and an undersea cable system capable of saving a branch line when a problem involving ground fault occurs in a power feed line on a branch station side.
