Abstract

The optical module provided by the invention comprises a circuit board which is provided with a TEC control circuit, a TEC electrically connected with the TEC control circuit, a substrate mounted on the TEC in a surface mounting manner, at least three light-emitting components which are respectively mounted on the substrate, are electrically connected with the circuit board and are used for generating signal light, and at least two thermistors which are dispersedly arranged on the substrate wherein the thermistors are close to the light-emitting assemblies, the thermistors are connected with the TEC control circuit, and the number of the thermistors is smaller than that of the light-emitting assemblies; and the TEC control circuit obtains a detection voltage through the thermistors, and drives the TEC according to the detection voltage. The adjustment and control of the temperature of the plurality of groups of light-emitting assemblies are realized only by combining one TEC and the TEC control circuit with the plurality of thermistors, the complexity of a temperature control system in the multi-transmission-channel optical module is controlled, and the complex control circuit and huge power consumption of the TEC control circuit are avoided.
