Abstract

The invention discloses an optical module, comprising: a top cover and a base, and the base is provided with an isolation rib and a fixing frame, and the fixing frame is used for shielding the front ends of the light receiving device and the light emitting device; the top cover is used for shielding the light receiving device and the light emitting device The upper end of the device; the bottom of the base is used to shield the lower end of the light receiving device and the light emitting device; When packaging the light receiving device and the light emitting device, the isolation rib is located between the light receiving device and the light emitting device, the isolation rib is used to shield the right end of the light receiving device and the left end of the light emitting device, and the two side walls of the base are used to shield the light receiving device The left end of and the right end of the light-emitting device. It can be seen that the optical module can isolate the light-receiving device and the light-emitting device, avoiding crosstalk caused by the electromagnetic waves radiated from the two optical devices and affecting each other, thereby ensuring the performance of the two devices and the normal operation of the optical module.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to an optical module. Background technique [0002] An optical module generally refers to an integrated module for photoelectric conversion, which is usually packaged by a light receiving device, a light emitting device and a circuit board. In the process of signal conversion, after the optical receiving device receives the optical signal, it will convert the optical signal into an electrical signal, and then transmit the electrical signal to the optical emitting device through the circuit board; after receiving the electrical signal, the optical emitting device will The electrical signal is converted into an optical signal and emitted, thereby realizing the conversion of the photoelectric signal. [0003] When the optical module is working, both the light receiving device and the light emitting device will radiate electromagnetic waves outward. Since the light...
