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
[0005] 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

A bidirectional optical transmitting and receiving secondary module includes the light-emitting component, at least one photic component and the loading piece which has at least two grooves. At least one of the grooves is combined with the filter. The light signal outputted from the light-emitting component is refracted by the filter and reflected by the groove without combining the filter to the optical conduction component. The invention can reach the precise optics contraposition and improves the reliability of the optics component but decreases the cost, also it can improve the light coupling efficient by combining the double lens structure.

Description

technical field [0001] 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 [0002] 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 receiving optical fibers on the same optical fiber to save the layout of the optical fiber network. In a wavelength multitasking optical communication system, different optical signals come from different signal sou...
