Problems solved by technology

[0004] In the prior art, since the light-receiving element and the light-emitting element are in the same space, and the distance is relatively close, the signal from the transmitting end is easily connected to the receiving end
In order to reduce crosstalk, shielding parts are usually used to separate them from the middle, so as to suppress the signal from being transmitted to the light-receiving element. However, in this way of setting shielding parts, the shielding parts occupy a certain amount of space, resulting in tight installation space on the circuit board in the housing. The problem

Abstract

The present invention discloses an optical module. The optical module includes a printed circuit board, a light emitting element, a light receiving element and an optic fiber port corresponding to the light emitting element and the light receiving element; the printed circuit board comprises a first surface and a second surface which are arranged oppositely; the light receiving element is mounted on the second surface of the printed circuit board; and the light emitting element is mounted on the first surface of the printed circuit board or is adjacent to an end surface of the printed circuit board. According to the optical module of the invention, the light emitting element and the light receiving element are arranged at the two sides of the printed circuit board, and therefore, the signal crosstalk of the light-emitting element and the light-receiving element can be effectively reduced, and the performance of the optical module can be improved; and a shielding component is not required, and therefore, the problem of space occupation caused by the shielding component can be avoided.

Description

technical field [0001] The present application belongs to the technical field of optical communication, and in particular relates to an optical module. Background technique [0002] The optical module is composed of optoelectronic devices, functional circuits and optical ports. Among them, optoelectronic devices include two parts: emission and reception. To put it simply, the main function of the optical module is to realize photoelectric conversion. At the sending end, the electrical signal is converted into an optical signal. After transmission through the optical fiber, the optical signal is converted into an electrical signal at the receiving end, thereby realizing the transmission of information. [0003] Currently commonly used optical modules use the light-emitting element and the light-receiving element to be contained in the same plane space. figure 1 The structure of the QSFP+ optical module in the prior art is shown as an example. The QSFP+ optical module includ...
