The present disclosure provides a remote optical path switching node connects two loop networks in which optical fibers are connected in a loop form. The two loop networks include an upper loop close to a tester that emits a test beam and lower loops away from the tester. The remote optical path switching node includes: an optical cross-connect connected to an optical fiber included in the lower loop; a test optical coupler connected to a test optical fiber through which a test beam propagates in the upper loop and which is connectable to the optical cross-connect; a control unit configured to control the connection between the optical cross-connect and the test optical coupler; and a light extraction unit configured to detect a test beam propagating in the upper loop and emitted from the test optical coupler or the optical cross-connect.
A remote optical path switching node configured to connect two loop networks in which optical fibers are connected in a loop form,
A monitoring method executed by a remote optical path switching node configured to connect two loop networks in which optical fibers are connected in a loop form,
