CONSTITUTION: Each node of an annular optical communication network(6) includes an optical branch couplers(310a,340a) having a demultiplexer and a multiplexer each with 1xN capacity. A pair of switching units(210a,280a) are connected with an optical fiber line for protectively switching. Each node also includes a pair of circulators(410a,480a) connected between the optical branch couplers(310a,340a) and the pair switching units(210a,280a). Two ports of the circulators(410a,480a) are connected to the optical switching units(210a,280a) and one port thereof is connected to the optical branch couplers(310a,340a). In this case, a signal inputted to the first port is outputted to the second port, and a signal inputted to the second port is outputted to the third port. The optical switching units(210a,280a) switch an optical signal by discriminating a case where an optical fiber link is normal with respect to two output terminals respectively connected to the two ports of the circulators(410a,480a) and a case where the optical fiber link has an error.
