Abstract
The present invention related to a single-core bidirectional optical transceiver module, which mainly includes: optical transceiver sleeve, laser diode package, photoelectric sensor, filter glass & combined-seat; wherein, the combined-seat is rectangular, whose surface is made of stainless steel, the part included within it is made of plastic material, to be formed by way of integration; besides it connects with the optical transceiver sleeve at the right side, connects with the laser diode package at the left side, connects again with the photoelectric sensor at its top; such three components are combined in the combined-seat and form an improved structure for single-core optical transceiver module, so as to provide the product of this creation with the advantages of easy workability and low cost.
Description
BACKGROUND OF THE INVENTION

1. Field of the Invention


The present invention related to a single-core bidirectional optical transceiver module, in particularly, the optical transceiver module is formed through the combined-seat by way of integration; it uses plastic material and stainless steel to combine the optical transceiver sleeve, laser diode package and photoelectric sensor, so as to reduce cost and facilitate the assembly.


2. Description of the Prior Art


General traditional optical transceiver module adopts a light emission component and a light receiving component, which are placed and fixed at the connection part of the upper cover & the lower cover in a separate form; wherein, the light emission component and the light receiving component works separately, the light emission component is laser diode component, used to emit laser light; the light receiving component is optical diode component, used to receive the optical signal sent by the optical fiber, which has the drawbacks of higher cost and difficult to process.


SUMMARY OF THE INVENTION

The present invention related to a single-core bidirectional optical transceiver module; wherein, the two roles of emission and receiving are integrated in the combined-seat, so as to combine the optical transceiver sleeve, laser diode package and photoelectric sensor; without the separation of the emission component & the receiving component, single outlet can take the roles of emission and receiving; besides the combined-seat is formed by way of integration and adopts composite material, i.e., its appearance is made of stainless steel, the part included within it is made of plastic material, so as to provide the product of this creation with the features of easy workability and low cost.


To make the structure & features and functions of this creation more clear and detailed, the execution example with following graph & figure numbers is offered as below.
