Since the two elastic arms 22 of the push-pull member 2 are respectively adjacent to the two wide wall portions 51 of the casing 5 and the main body 21 is adjacent to one of the narrow wall portions 52, the push-pull member 2 does not increase the narrowness of the optical fiber connector 1 in another narrow portion. The thickness of the side of the wall portion 52 allows the sides of the two fiber connectors 1 not provided with the push-pull members 2 to be brought close together to reduce the distance between the two fiber connectors 1. Since the length and width of the dual fiber adapter interface generally applicable to the MPO connector are 30 mm and 10 mm, respectively, the length and width of the interface of the dual fiber adapter (not shown) for the SC connector are 26.2 mm and 9.6 mm, respectively. The fiber optic connectors 1 of the same group of fiber optic connection devices 100 as described above can be applied together to be suitable for SC dual fiber optic adapters. In other words, the optical fiber connection device 100 can also be applied to the SC dual fiber adapter. Therefore, the user can select the SC connector or the MPO connector by installing the SC dual fiber adapter, thereby increasing the flexibility of use and reducing the existing use. The interface size of the dual fiber adapter for the MPO connector.

Referring to FIG. 7 and FIG. 8, a second embodiment of the novel optical fiber connecting device 100 includes two optical fiber connectors 1 and a push-pull member 2. Each of the optical fiber connectors 1 is the same as the first embodiment and will not be repeated here. The push-pull member 2 is coupled to the two fiber optic connectors 1 and the two fiber optic connectors 1 are arranged side by side in such a manner that the narrow wall portions 52 of the casings 5 are adjacent to each other. The push-pull member 2 has an optical fiber interposed therebetween. A main body 21 extending between the connectors 1 and extending in the insertion and removal direction D for hand-held, and two pairs extending from the main body 21 to the two optical fiber connectors 1 to respectively clamp the elasticity of the two optical fiber connectors 1 Arm 22. The structure of each pair of elastic arms 22 is the same as that of the first embodiment, and will not be repeated here.

Referring to FIG. 9 and FIG. 10, in the second embodiment, the optical fiber connecting device 100 can be disposed corresponding to one adapter 9. As long as the main body 21 of the push-pull member 2 is hand-held, the two optical fiber connectors 1 can be inserted and removed at the same time. Moreover, the portion of the main body 21 of the push-pull member 2 located between the two fiber optic connectors 1 can be relatively thin, and the two fiber optic connectors 1 can be applied to the SC dual fiber optic adapter, which has the same SC double fiber adapter as the first embodiment. The flexibility of the above, and can reduce the interface size of the existing dual fiber adapter for MPO connectors.

In summary, the metal piece 6 is fixed to the insulating case 3 to form the first convex portion 61 and the second convex portion 62, which can have better strength than the plastic material to increase durability and reliability. Moreover, since the two elastic arms of the push-pull member are designed as two wide wall portions of the casings of adjacent optical fiber connectors respectively, the optical fiber connecting device can be applied to the MPO dual fiber adapter and the SC dual fiber adapter, Allows users to increase the flexibility of using SC dual fiber adapters and reduce the interface size of existing dual fiber adapters for MPO connectors.
