[0032] Specifically, the mounting slot 4071 can be conveniently matched with the I / O port, thereby satisfying a variety of fiber optic branching options.

[0033] That is, when in use, the input and output ports can be allocated independently and conveniently to meet the diverse needs of users.

[0036] See Figure 2 A cover plate 204 is provided at the opening end of the installation cavity 201 , and the cover plate 204 is used to be fixedly matched with the installation cavity 201 .

[0037] Specifically, the cover plate 204 can seal the installation cavity 201 more conveniently.

[0038] See Figure 4 Two wire loops 409 are formed at the bottom of the installation cavity 201 .

[0039] Specifically, the wire loop 409 can be wired with the optical fiber, thereby reducing bending damage to the optical fiber.
