Abstract
Description
Technical Field
[0001] This utility model relates to the field of optoelectronics, specifically to the field of 155Mbps optical emitting components. Background Technology
[0002] For traditional optical transmitting components in optical communication, please refer to [link / reference]. Figure 1 An optical emitting assembly typically consists of a laser 1', a tube 2', and an adapter 3'. The adapter 3' comprises a ceramic ferrule 31', an open ceramic sleeve 32', and a metal component 33'. The primary function of the ceramic ferrule is to achieve the physical connection of optical fibers (also known as fiber cold splicing), and it is often used in conjunction with a ceramic sleeve. For high-speed emitting assemblies, a ceramic ferrule with an 8° bevel is required to reduce the impact of reflected light. However, for low-speed optical emitting assemblies such as FP (Fabry-Perot lasers), the impact of reflected light is relatively small. To enhance product competitiveness, the ceramic ferrule in the adapter may be removed at the request of the customer. Utility Model Content
[0003] The purpose of this invention is to provide a 155Mbps optical transmitting component without a ceramic ferrule.
[0004] To achieve the above objectives, this utility model provides a 155Mbps optical emission component, which consists of a laser, a tube, and an adapter. The laser chip is a 155Mbps 1310nm FP laser chip. A closed ceramic sleeve is provided inside the metal part at the front end of the adapter, and a straight fiber tail is inserted into the closed ceramic sleeve.
[0005] By adopting the above solution, the 155Mbps optical transmitter component of this utility model without ceramic ferrules does not use traditional ceramic ferrules in the adapter, thereby saving costs and reducing the length of the TOSA. Attached Figure Description

[0011] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0012] Please see Figure 2 This utility model discloses a 155Mbps optical emitting component without a ceramic ferrule, mainly composed of a laser 1, a tube body 2, and an adapter 3. The laser 1 mainly consists of a 155Mbps 1310nm FP laser chip, an MPD chip, a tube socket, a tube cap, a ceramic plate, gold wire, silver paste, etc.; the adapter 3 has a metal part, and a closed ceramic sleeve 4 is provided inside the metal part, with a straight fiber tail 5 inserted into the closed ceramic sleeve 4.
[0013] The optical path of the 155Mbps optical transmitting component of this utility model is as follows: the laser emitted by the 155Mbps FP laser chip first passes through the lens on the cap, and then the laser is focused onto the optical plane of the adapter 3, which also just contacts the optical plane of the straight pigtail 5 inserted from the outside, so that the laser enters the pigtail.
[0014] This invention not only eliminates the need for specially processed ceramic inserts, but also eliminates the complex processing of ceramic inserts, fiber tails, and ceramic sleeves, thus reducing costs.
[0015] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent shape or structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
