Claim:
1. An optical branching/insertion device comprising: a trunk-side detection/branching unit which detects a failure of a trunk-side optical signal inputted from the trunk side, outputs detection result of the failure of the trunk-side optical signal as a first detection result, splits the trunk-side optical signal, and sends the split signals respectively to the trunk side and to the branch side; a branch-side detection unit which detects a failure of a branch-side optical signal inserted from the branch side, outputs detection result of the failure of the branch-side optical signal as a second detection result, and sends the branch-side optical signal as an insertion signal; an insertion signal adjustment unit which outputs the insertion signal after adjusting pass-through degree of the insertion signal on the basis of the first detection result, as a first adjusted signal; a trunk signal adjustment unit which outputs the trunk-side optical signal after adjusting pass-through degree of the trunk-side optical signal on the basis of the second detection result, as a second adjusted signal; and a combining/output unit which outputs, an optical signal into which the first adjusted signal and the second adjusted signal are combined together, as a trunk-side output optical signal, wherein the insertion signal adjustment unit comprises: wherein the trunk signal adjustment unit comprises:
