[0003] In the prior art, the optical module is provided with an optical device and a photoelectric converter, wherein the light receiving device is connected between the optical fiber and the photoelectric converter, and is used to input the optical signal in the optical fiber into the photoelectric converter, Or input the light emitted by the photoelectric converter into the optical fiber; but because the photoelectric converter will generate electromagnetic waves in the working state, and because there is no electromagnetic shielding structure in the existing optical devices, the electromagnetic waves generated by the photoelectric converter It is easy to leak out through the optical device, which will cause signal interference to other external electronic devices, which will cause the optical module to fail to meet the requirements of electromagnetic shielding indicators

The invention relates to the technical field of optical fiber communication, in particular to a novel optical device and an optical module thereof. The optical receiving device comprises an optical fiber interface and a tube seat; an electromagnetic shielding part is arranged between the inner end of the optical fiber interface and the outer end of the tube seat; an opening part used for accessingan optical fiber is formed in the outer end of the optical fiber interface; a containing cavity used for containing a photoelectric converter is formed in the inner end of the tube seat; and a light-transmitting hole allowing light to pass through is formed in the electromagnetic shielding part. According to the optical receiving device, the electromagnetic shielding part is arranged between theoptical fiber interface and the tube seat, so that electromagnetic waves can be effectively prevented from leaking to the outside through the optical fiber interface of the optical receiving device, the signal interference of the electromagnetic waves to other electronic devices is effectively reduced, and the optical module can meet the requirements of electromagnetic shielding indexes.
Description
technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to a novel optical device and an optical module with the novel optical device. Background technique [0002] Optical communication is a mainstream communication method nowadays; in the existing optical communication process, it mainly goes through three steps, that is, first converting electrical signals into optical signals, then using optical fibers to transmit optical signals, and finally converting The optical signal on the optical fiber is re-converted into an electrical signal; and in the above optical communication process, it needs to use an optical module to convert the optical signal into an electrical signal, or convert the electrical signal into an optical signal. [0003] In the prior art, the optical module is provided with an optical device and a photoelectric converter, wherein the light receiving device is connected between the optical fiber and ...
