Summary: 
We describe the design and simulation of a suitable branching ratio for an optical coupler for a cable re-routing operation support system with no service interruption, and report our experimental results. We also show the risk analysis, and report that the branching ratio was 0.47 where the probability was 99.7% that the maximum acceptable cable loss of a detour line was more than that of the current line.
