Problems solved by technology

[0003] 1. The light-emitting component 3 and the light-receiving component 4 must be installed in different positions, which is very troublesome in installation and increases the difficulty of production
[0004] 2. The reflector 6 used to refract light beams is very precise, so the unit price is also very expensive, resulting in a large increase in the cost of the product, which is difficult to be generally accepted by the market
[0005] 3. Because the light beam must be refracted to a certain correct position, the relative position of each component must also be extremely accurate in installation, thus increasing the difficulty in manufacturing, making the product yield rate unable to be effectively improved, and showing its shortcomings

Embodiment Construction

[0021] Such as Figure 1 to Figure 3 As shown, the present invention relates to a hollow-encapsulated transmitting module 100 in a two-way optical transceiver module, which includes: a light-receiving component 1; a light-emitting component 2, which is packaged on the light-receiving surface 11 of the light-receiving component 1; The photomask 3 is made of light-transmitting material, and contains a disk portion 31 straddling the periphery of the light-emitting component 2, and a concave portion 32 is recessed at the central bottom of the disk portion 31, and the concave portion 32 is in a hemispherical shape to match The light-emitting component 2 is nested so that the light beam L2 emitted by the light-emitting component 2 is condensed to the entrance 41 of a bundle of optical fibers 4 , and the light beam L2 emitted by the light-emitting component 2 is prevented from returning to the light-emitting component 2 again.

Abstract

The invention is a hollow-packaged transmission module in bidirectional optical transmit-receive module, including: a light receiving component and a light-emitting component packaged on the light-receiving surface of the former; and a concave focusing cover made of light transmitting material and containing a disc part spanning the periphery of the light-emitting component, and there is a valley made on the bottom of the disc part, the valley is a slightly hemispherical surface in shape so as to fittingly cover the light-emitting component, thus focusing the light beams from the light-emitting component to an optical fiber inlet and preventing them from being reflected back to the light-emitting component.

Description

technical field [0001] The present invention relates to a hollow-encapsulated emission module in a two-way optical transceiver module, in particular to a concave-shaped condenser cover on the light-receiving surface side of the light-emitting assembly, so as to condense the light beam emitted by the light-emitting assembly. It enters a bundle of optical fibers, and prevents the light beam emitted by the light-emitting component from returning to the light-emitting component again. Background technique [0002] Currently used in bidirectional transmission optical transceiver modules, as shown in U.S. Patent No. 6,188,495 (OPTICAL TRANSMISSION-RECEPTION APPARATUS0), the disclosed module mainly includes a bundle of optical fibers 11, a light emitting component 3, a reflector 6 and a A light receiving component 4, and a lens 8 can be installed between the optical fiber 11 and the light receiving component 4, wherein the reflective sheet 6 can reflect the light beam generated by ...
