Dust Caps and Fiber Connector Assemblies for Fiber Optic Adapters

Abstract

The invention discloses a dustproof cap of a fiber optic adapter, which is suitable for being assembled into a port of the fiber optic adapter, and an indicator light is arranged at a port of the fiber optic adapter. The dustproof cap is made of a transparent material. A reflective surface is provided inside the dust cap. The jumper fiber optic connector plugs into the other port of the fiber optic adapter. The light emitted from the indicator light is incident on one side of the reflective surface, is reflected by the reflective surface toward the outer end of the dustproof cap, and is output from the outer end of the dustproof cap. The working status of the indicator light on the fiber optic adapter can be seen clearly at the outer end. In addition, the laser emitted from the optical fiber of the jumper fiber optic connector is incident on the other side of the reflective surface, is reflected by the reflective surface to the side of the dust cap, and is output from the side of the fiber optic adapter without being transmitted from the anti-dust cap. The outer end of the dust cap is output, so it can effectively prevent the laser emitted from the jumper fiber from causing damage to human eyes.

Description

technical field [0001] The invention relates to a dustproof cap of an optical fiber adapter and an optical fiber connection assembly with the dustproof cap. Background technique [0002] At present, the main function of the dustproof cap used in the fiber optic adapter is to prevent dust from entering the inside of the fiber optic adapter. When in use, the dustproof cap is inserted into a port (user end) of the fiber optic adapter, and the jumper fiber optic connector is inserted into the fiber optic adapter. in the other port (jumper end). [0003] In the prior art, the dustproof cap mainly has the following two technical solutions: (1) In the intelligent optical fiber management system, the dustproof cap of the fiber optic adapter is made of transparent material, so that the dustproof cap can be seen through the dustproof cap The working status of the indicator light arranged on the bottom of the fiber optic adapter; (2) in the conventional fiber optic adapter, the fiber ...

AI Technical Summary

Problems solved by technology

[0004] For the aforementioned existing technical solutions, if the dustproof cap is made of a light-transmitting material, the human eye can observe the working status of the indicator light arranged at the bottom of the fiber optic adapter. However, when using a dustproof cap made of a light-transmitting material, The laser light emitted from the jumper fiber at the other end of the fiber adapter passes through the dust cap and is output from the outer end face of the dust cap. Therefore, the use of a light-transmitting dust cap cannot prevent the laser from being transmitted from the other end of the fiber adapter. easy to damage human eyes

If a dust cap made of black or dark material is used, it can prevent the laser light transmitted from the other end of the fiber optic adapter, but the human eye cannot see the working status of the indicator light

[0005] In addition, in the aforementioned prior art solutions, even if the dustproof cap is made of light-transmitting materials, since the optical fibers emitted by the indicator lights are scattered in all directions, it is difficult for the human eye to clearly or easily see them in the outdoor sunlight environment. To see the working status of the indicator light
