Technical Field

[0001] This utility model relates to the technical field of wavelength division multiplexers, and specifically to a novel wavelength division multiplexer. Background Technology

[0002] A wavelength division multiplexer is a device that uses wavelength division multiplexing (WDM) technology. Optical signals carrying information can be transmitted through optical fibers within the wavelength division multiplexer.

The optical conditioning device is usually connected to the ferrule and external optical fiber of the wavelength division multiplexer. However, during use, the optical conditioning device is often susceptible to damage from external forces, which can affect the normal use of the wavelength division multiplexer.

[0004] Therefore, further improvements are needed. Utility Model Content

[0012] As a specific embodiment, the outer protective tube and the concentric straight sleeve are arranged concentrically, with the outer protective tube sleeved on the outside of the concentric straight sleeve and the two fitting together tightly.

[0013] As a specific embodiment, the concentric straight sleeve is formed by processing glass material.

An inner optical fiber 4 is provided between the optical conditioning assembly 5 and the ferrule 1 at a position corresponding to the inside of the outer protective tube 3. The inner optical fiber 4 is connected and cooperates with the optical conditioning assembly 5 and the ferrule. By setting the outer protective tube 3, the chance of damage to the optical conditioning assembly 5 can be effectively reduced, thereby improving the stability and reliability of the wavelength division multiplexer. At the same time, the outer protective tube 3 can also protect the connection structure between the ferrule 1 and the optical conditioning assembly 5, further improving the stability and reliability of the wavelength division multiplexer.

[0022] Furthermore, the insert part 1 is formed by processing ceramic material.

[0023] Furthermore, the outer protective tube 3 is formed by processing metal material.

The concentric straight sleeve 6 can further protect the light adjustment component 5, while ensuring the concentricity between the front focusing part 51 and the rear focusing part 52.

[0027] Furthermore, the outer protective tube 3 and the concentric straight sleeve 6 are arranged concentrically with each other. The outer protective tube 3 is sleeved on the outside of the concentric straight sleeve 6 and they fit together tightly, which can further reduce the chance of accidental displacement of the concentric straight sleeve 6 and the light adjustment component 5.

[0028] Furthermore, the concentric straight sleeve 6 is formed by processing glass material.
