<p>An optical-phase monitoring apparatus includes an optical switch, an optical-phase detecting circuit, and a display circuit. The optical switch multiplexes signal light and a control optical pulse, and outputs a portion of the signal light that overlaps with the control optical pulse in time as output light. The optical-phase detecting circuit detects an optical phase of the output light. The display circuit displays information concerning the optical phase.</p> |
