Problems solved by technology

As shown in the figure, in the filter assembly structure 2, each filter 24 is combined with its fixing seat 28 in a single-sided sticking manner. If encountering environmental changes, such as temperature changes or vibrations, each filter in this design The mirror 24 is extremely prone to displacement, deformation or even falling off
[0006] In the design of the existing optical transceiver components, due to the lack of tight connection between the components, the optical signal is easy to leak out of the unsealed joint gap, so the problem of mutual interference between the optical components is more serious

Abstract

The invention discloses a bidirectional light receiving and transmitting submodule which at least comprises a light-emitting component, at least one light receiving component and a load bearing component, wherein the load bearing component is provided with at least two grooves; at least one groove is combined with a filter lens; a light signal output by the light-emitting component is refracted by the filter lens and reflected by the groove, which is not combined with a filter lens, to a light conduction component; and the light signal, which is transmitted and output by the light conduction component, is reflected by the groove, which is not combined with the filter lens, and refracted by the filter lens to the light receiving component. The bidirectional light receiving and transmitting submodule realizes accurate optical contraposition through the modular structure design, relatively enhances the reliability of the optical components, reduces the number of used components, lowers the production cost, simplifies the production process, and can enhance the coupling efficiency by integrating the double-lens structure.

Description

[0001] This application is a divisional application with the application number 200510103169.0, the application date is September 20, 2005, and the invention name is "two-way optical transceiver sub-module". technical field [0002] The invention relates to an optical transceiver module, in particular to an optical transceiver sub-module for wavelength multi-task bidirectional transmission applied in an optical communication access network. Background technique [0003] Optical transceivers convert optical signals from optical fibers into electrical signals, or convert electrical signals into optical signals for optical fiber transmission. With the rapid development of the optical communication industry, the bidirectional multi-task optical transmission network has become the mainstream of the optical communication industry. The so-called two-way multitasking transmission network is to use a wavelength multiplexer to integrate two original independent transmission and receiv...
