Optical amplifying apparatus

摘要

A computer-controlled optical amplifying apparatus, which includes an optical amplifying unit including an optical amplifying medium and an optical amplifying control unit controlling the optical amplifying unit under the control of a computer. This optical amplifying control unit is constituted by a status monitoring unit for monitoring the status, an optical output control unit for controlling the optical amplifying unit in accordance with the result of monitoring of status; and a status restoring unit for initializing the control status of the optical output control unit by initializing the computer when detecting an occurrence of the abnormal status by the result of monitoring of status and restoring the optical output control unit to the control status before occurrence of the related abnormal status within a relaxation time inherent in the optical amplifying medium occurring accompanied with this initialization.
