The invention discloses a receiving unit of an optical module. The receiving unit is an integration of an optical receiving module, a level converter, a reference voltage source and a decision comparator. The optical receiving module is connected with an input end of the level converter. An output end of the level converter is connected with a first input end of the decision comparator. The reference voltage source is connected with a voltage adjusting end of the level converter and a second input end of the decision comparator. The invention further discloses the optical module. By adopting the above manner, the optical module and the receiving unit thereof are capable of reducing the influence of noises, and the sensitivity is guaranteed.
Description
technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to an optical module and a receiving unit thereof. Background technique [0002] The optical module is an important device in the optical fiber communication system. It has the function of photoelectric conversion and received signal detection, and can transmit and receive signals at the same time. [0003] At present, most optical modules are powered by a single power supply, and the optical power signal received by the optical module is relatively sensitive. When judging an optical power signal with a large dynamic range, if the threshold voltage is set low, the judgment point is easily overwhelmed by ground noise , if the threshold voltage is set higher, the sensitivity will not meet the requirements. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide an optical module and its receiving unit, which ...
