Abstract
This application discloses a temperature feedback control apparatus, method. The method includes two electric switches, a feedback control unit and an optical component. A first electric switch is configured to control that only a first channel of at least two channels that correspond to the first electric switch is conducted at a moment, to feed back an optical signal of a target optical component connected to the first channel to the feedback control unit. The feedback control unit is configured to calculate temperature of the corresponding optical component based on an electrical signal converted from the optical signal, to obtain a control signal. The second electric switch is configured to control, when the first channel is conducted, that only the second channel is conducted, to transmit the control signal to the target optical component to adjust its temperature. The optical component connects to both the first and second channels.
