Abstract
A communication device configured to include a communication unit a monitoring unit, a control unit, and an authentication unit. The communication unit transmits and receives an optical signal to and from an opposed device via a transmission line. The monitoring unit monitors a transfer state of the transmitted optical signal. The control unit transmits a signal based on a dummy pattern instead of actual data when the monitoring unit detects that a failure occurs in transfer of the optical signal. The authentication unit authenticates start of transmission of a signal based on the actual data, when the monitoring unit detects elimination of the failure, while the signal based on the dummy pattern is being transmitted. Moreover, the control unit transmits the signal based on the actual data instead of the dummy pattern when the start of transmission is authenticated by the authentication unit.
