Abstract
An optical communication apparatus includes an optical signal transmitter for outputting an optical signal, an optical switch device for switching a route of the optical signal, a drive controller for supplying a drive current for controlling a route switching to the optical switch device, a cooling device for cooling the optical switch device on the basis of a control signal, a temperature controller for transmitting the control signal to the cooling device in order to keep a measured temperature at a specific temperature, where the measured temperature is related to a temperature of the optical switch device.
