Description

Technical Field

[0001] The utility model relates to the field of optical communications, in particular to a clamp adapted for coupling of two-terminal devices in a multi-mode combined BOSA coupling platform. Background Art

[0002] In existing multi-mode BOSA coupling platforms, the tube fixture is often only suitable for coupling lasers of one wavelength. Switching to the next wavelength requires replacing the fixture or using another coupling device, which consumes a lot of time and manpower. Therefore, how to design a fixture that allows operators to quickly switch between laser coupling processes at different angles on the same platform is a current problem that needs to be solved. Utility Model Content

[0003] The purpose of the utility model is to solve the problem that when two mutually perpendicular lasers of a multi-mode combination BOSA device are coupled on the same machine, additional fixture replacement is required, and the position of the clamped device needs to be re-adjusted. A coupling fixture suitable for a multi-mode combination BOSA double-ended laser is provided.

[0004] The technical solution adopted by the present invention to achieve the above-mentioned purpose is: a coupling fixture suitable for multi-mode combination BOSA double-ended lasers, characterized in that: it includes a fixture body, a vertical slot is opened at one end of the fixture body, and a horizontal slot perpendicular to the vertical slot is opened toward the middle of the fixture body. The two slots are connected and are used to place the tube body to be coupled. An L-shaped top block is connected to the side wall at the inflection point of the two slots, and the top block is connected to a top screw for controlling its left and right movement.

[0005] The end of the horizontal slot is provided with a sloped extension space suitable for pipes with different interface forms.

[0006] An L-shaped slot is provided on the side wall at the inflection point of the two slots, an L-shaped top block is connected in the L-shaped slot, and a top block cover is used to cover the top of the top block.

[0007] The top block cover plate is fixed by a cover plate limiting column on the clamp body.

[0008] The top screw fixes the clamp body and the top block through two coaxial center holes opened on the clamp body and the top block.

[0009] The coaxial center hole is a M2.5*0.45 threaded through hole.

[0010] This new fixture features a pre-set clamping space for TOSA coupling with two perpendicular ends, and incorporates a limiter to constrain the device's position. This ensures that the receiving ports of the two lasers are aligned on the same axis during coupling, enhancing the consistency of the received light position when clamped at different angles. Furthermore, the fixture also reserves space for BOSA pigtails and receptacle ends with different interface types, improving compatibility with various devices. In summary, this new fixture offers flexibility and adaptability, along with stability and ease of operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The end of the horizontal slot 7 is provided with a sloped extension space 8 suitable for pipes with different interface forms.

[0018] An L-shaped slot is provided on the side wall at the inflection point of the two slots, an L-shaped top block 5 is connected to the L-shaped slot, and a top block cover plate 2 is used to cover the top block 5 .

[0020] The top screw 3 is passed through two coaxial holes on the clamp body 1 and the top block 5 to fix the two.

[0021] The coaxial center hole is a M2.5*0.45 threaded through hole.

[0022] Figure 2 and Figure 3 This diagram shows a BOSA secured using this utility model. As can be seen, this design effectively achieves perpendicular TOSA coupling, while maintaining consistent X and Y directions for the receiving optical port, significantly improving the fixture's usability and operability. Testing has shown that the entire assembly is easy to assemble, offers high yield rates, and offers stable performance, facilitating production.
