The problem of time and effort, in turn, achieves the effect of accurately locating the position of the fiber interface and quickly extracting the fiber interface.

In an alternative embodiment of the invention, as shown in Figure 2, the tail of the securing recess 12 is provided with a handle 22 having a lumen.

Wherein, as shown in FIG. 3, the handshake (equivalent to the handle 22) is convenient for the user to use, and the outer layer of the handshake can be wrapped with a layer of elastic material to make the user feel more comfortable.

In an alternative embodiment of the present invention, as shown in FIG. 2, the tail portion of the upper jaw 14 is coupled to the upper side of the inner cavity of the handle by an elastic member 24, and the lower side of the middle portion of the handle has a corresponding portion with the tail of the upper jaw 14. Open.

Among them, the elastic member makes the upper jaw 14 open in a natural state, which is convenient for the user to locate the optical fiber interface.

In an optional embodiment of the present invention, as shown in FIG. 2 and FIG. 4, the open port is a through hole, and the fiber take-up button 42 is disposed in the through hole, one end of the fiber take-up button 42 is exposed, and the fiber take-up button 42 is another. One end is connected to the tail of the upper jaw 14 .

The width of the fiber optic plug-in of the embodiment of the present invention may be only the width of one fiber optic interface. The fixing groove 12 is fixed, and the side is removed, so that the device can be cut from the side when the fiber is taken. In this way, the fiber can be taken directly from the front, or the fiber can be taken from the side. There is a groove at the bottom, so that the fiber-optic interface can be well fixed. Keeping one side to facilitate the fixing of this interface prevents the position of the interface from being well positioned during fiber removal. The user can position the interface well based on the sense of touch. The handshake is easy for the user to master.

1) In a high-density environment, the laser interface is on the left and right sides of the board, and each laser is inserted into two fibers side by side. When it is suspected that a certain fiber is damaged, it is necessary to extract one fiber. In this case, the optical fiber insertion and removal device of the embodiment of the present invention can quickly locate the position of the optical fiber interface and smoothly take the fiber.

2) In a high-density fiber interface environment, for example, two SOPs (Smart Optical Protection) boards are fully populated with optical fibers. In this case, the fiber interface in the middle position needs to be replaced. At this time, the density of the fiber interface is very high, there is basically no way to operate by hand, and because of the large number of fibers, the position of the fiber interface cannot be well observed. At this time, the optical fiber insertion and removal device of the embodiment of the present invention can determine the position of the fiber to be taken only by the tactile sensation during the operation of the device, and smoothly extract the fiber.

3) In the laboratory operating environment, the operating space is relatively narrow, and the optical fiber inserter of the embodiment of the invention is utilized, thereby facilitating the insertion and removal of the optical fiber.
