Problems solved by technology

The single-mode fiber used for transmission in the ferrule component, the mode field diameter of the single-mode fiber is usually about 9 μm. There are factors such as position tolerances. It is difficult to completely center the fiber core during coupling and is very sensitive to dust. The core diameter of 9 μm makes the loss value increase sharply if there is a slight size deviation or dust enters the docking surface. Therefore, after coupling It is difficult to obtain a loss value that meets the requirements, which leads to a large transmission loss when the optical path is connected through the ferrule component

Embodiment Construction

[0017] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] The specific embodiment of ferrule part of the present invention, as figure 1 As shown, the ferrule component 1 includes a ferrule housing 11, and the ferrule housing 11 is provided with an optical fiber passage 12 for inserting and fixing the optical fiber 2. The ferrule component 1 in this embodiment is a multi-core ferrule. The multi-core ferrule can connect multiple optical fibers 2 in one ferrule part, which can reduce the cost. In other embodiments, the multi-core ferrule can also be selected. In other embodiments, the ferrule component may also be a single-core ferrule. In this embodiment, the multi-core ferrule is specifically selected as an MT ferrule, and the optical fiber 2 inserted in the ferrule part 1 is an optical fiber with an enlarged mode field diameter at the butt end, that is, a single fiber with a mode field diameter greater ...

Abstract

The present invention relates to a ferrule member. The ferrule member includes a ferrule shell, which has an optical fiber lead-through channel. Optical fiber is inserted into the optical fiber lead-through channel. The optical fiber is the single-mode optical fiber with an enlarged mode field diameter; and the mode field diameter at a butting end is more than 9[mu]m. Compared with the ordinary optical fiber, the influence of butt deviation and dust on the optical fiber with the enlarged mode field diameter is less; the optical coupling efficiency and the optical damage threshold of the optical fiber end face are significantly improved; and the transmission loss between the ferrule members is reduced.

Description

technical field [0001] The invention relates to a ferrule component. Background technique [0002] Optical path connections need to be made through ferrule components between optical fiber network node devices. The single-mode fiber used for transmission in the ferrule component, the mode field diameter of the single-mode fiber is usually about 9 μm. There are factors such as position tolerances. It is difficult to completely center the fiber core during coupling and is very sensitive to dust. The core diameter of 9 μm makes the loss value increase sharply if there is a slight size deviation or dust enters the docking surface. Therefore, after coupling It is difficult to obtain a loss value that meets the requirements, which leads to relatively large transmission loss when optical path connections are made through ferrule components. Contents of the invention [0003] The object of the present invention is to provide a ferrule component with low transmission loss when op...
