With increased demands for optical fiber cable removal, a system which reduces circuit quality degradation due to optical fiber switching has been strongly required. The optical switching elements and optical fiber switching systems were studied aimed at shortening optical switching time, optical loss and other optical specifications. However, the circuit quality degradation cannot be evaluated by these specifications. For this reason, it is important to study the circuit quality degradation due to optical fiber switching, and the study must comprehend the transmission system performance after optical fiber switching. To analyze the circuit quality degradation during optical fiber switching, the standard analysis model and the optimum analysis parameters were defined. Using them, the frame hunting time after optical fiber switching was studied theoretically and its influence on a working transmission system was estimated. The circuit degradation was evaluated experimentally with regard to an actual transmission system, and experimental results agreed with the estimation. Moreover, by utilizing the results of these studies, it was found that the reduction of circuit quality degradation can be realized firmly and the effect of these studies was verified.
