The embodiment of the invention provides an optical module and a temperature compensation method thereof. Concretely, a heating layer is manufactured on the flexible circuit board in the optical module by using the structural characteristics of connection of the flexible circuit board according to an optical receiving component and a printed circuit board; then the heating layer is controlled to perform heating according to the acquired temperature value of the optical module by using the processor in the optical module; and finally heating of the heating layer for the avalanche photodiode in the optical receiving component can be realized by using the mode of heat conduction to compensate the temperature change of the environment in which the avalanche photodiode is located, and finally the objective of improving performance deterioration of the avalanche photodiode under the low temperature can be achieved. According to the optical module, the receiving sensitivity of the optical module under the low temperature can be improved by additionally arranging the heating layer on the flexible circuit board without changing the structure or the components of the optical receiving component so that the optical module has the advantages of being simple in structure and convenient to implement.
Description
technical field [0001] The invention relates to the technical field of optical communication, in particular to an optical module and a temperature compensation method thereof. Background technique [0002] In recent years, trunk line transmission, metropolitan area network, access network, Ethernet, and local area network have increasingly adopted optical fiber for transmission; FTTC (Fiber To The Curb, fiber to the curb), FTTB (Fiber To The Building , Fiber To The Building), FTTH (Fiber To The House, Fiber To The Home), FTTD (Fiber To The Desk, Fiber To The Desktop) are constantly developing, and the optical contact is getting closer and closer to us. On each optical contact, an optical module is required to realize the conversion between optical signals and electrical signals. [0003] The optical module includes a light receiving component and a light emitting component. The optical receiving component is used to convert the received optical signal into an electrical si...
