[0027] It should be noted that the indoor optical splitter is usually installed on a wall, and fixing holes 33 penetrating the backplane 3 along a plurality of first directions X are provided on the backplane 3, and the backplane 3 is fixed to the wall by screws passing through the fixing holes 33.

[0028] A hanging portion 31 is provided on the backplane 3. The hanging portion 31 passes through the hanging hole 201 of the mounting plate 21, so that the hanging hole 201 is engaged with the mounting plate 21, and then the box body 2 is engaged with the backplane 3. Exemplarily, the hanging portion 31 may be a support rod (not shown in the figure), and the support rod passes through the hanging hole 201 to hang the mounting plate 21 on the hanging portion 31. Exemplarily, a convex block 202 protruding away from the backplane 3 is provided inside the mounting plate 21, the hanging portion 31 includes a groove 311, and the convex block 202 is engaged into the groove 311; the opening direction of the groove 311 is away from the ground, that is, the mounting plate 21 and the convex block 202 are engaged into the groove 311 of the hanging portion 31 from top to bottom. Further, along the first direction X, the sum of the thickness of the convex block 202 and the thickness of the mounting plate 21 is equal to the width of the groove 311, and the hanging portion 31 also limits the mounting plate 21 in the front-rear direction, improving the engagement stability. The hanging portion 31 may be a hook.

[0029] The backplane 3 can be a metal backplane 3, which has high hardness and strength, good load-bearing and supporting performance, and is not easily deformed or damaged; the metal backplane 3 is not easily combustible and has excellent fireproof performance, improving safety.

[0030] It can be understood that the indoor optical splitter in this embodiment is extremely convenient to install on the wall. Just fix the backplane 3 on the wall, and then snap the box body 2 onto the hanging part 31 of the backplane 3. The installation is firm, and there is no need to open the box body 2 during construction, avoiding touching the optical devices arranged in the box body 2, simplifying the installation steps, and improving the installation efficiency.

[0031] In some alternative embodiments, in combination with Figure 1 , Figure 2 , first side plates 22 and second side plates 23 are provided on the mounting plate 21 and are oppositely arranged along the second direction Y; first engaging structures 220 are respectively provided on the first side plates 22 and the second side plates 23, and each first engaging structure 220 includes a first elastic part 221 and a first engaging part 222; the box cover 1 is sleeved outside the box body 2, and a first limiting hole 11 is provided on the box cover 1, and the first engaging part 222 is snapped into the first limiting hole 11.

[0032] It can be understood that the first elastic part 221 can be a plastic spring piece, and the first elastic part 221 drives the first engaging part 222 to move along the second direction Y; when the box cover 1 is closed, the first engaging part 222 is snapped into the first limiting hole 11, and the first limiting hole 11 limits the first engaging part 222 to prevent the box cover 1 from loosening easily; when the box cover 1 is opened, the first engaging part 222 is pushed to move towards the inside of the box body 2, so that the first engaging part 222 is disengaged from the first limiting hole 11, thereby separating the box cover 1 from the box body 2. In this embodiment, the box cover 1 is sleeved outside the box body 2 and is snap-connected to the box body 2, preventing non-professionals from accidentally operating to open the box body 2, thereby avoiding damage to the optical devices inside the box body 2, enhancing the safety of the device, and also reducing the later maintenance cost.
