The side of the box body 1 opposite to the box cover 2 forms a bottom plate 11, and the side of the bottom plate 11 facing the inside of the box body 1 is a mounting surface. A plurality of cylindrical protrusions 12 protruding outward are formed on the bottom plate 11, and each cylindrical protrusion 12 is formed with a mounting hole 13 penetrating the mounting surface. The above accessories can be fixed to different positions of the bottom plate 11 by fasteners matching the mounting holes 13. The accessories include a fiber tray 3, an adapter panel 5, a cable management ring 6, etc.

[0033] Reference Figure 2 The fiber tray 3 is provided with a mounting plate 4 on the side facing the mounting surface. The mounting plate 4 is provided with a hole body matching the mounting hole 13. The fastener is inserted into the hole body to fix the mounting plate 4 on the mounting surface. The fiber tray 3 includes a base 31, an annular portion 32 and a limiting portion 33. The annular portion 32 is integrally formed on the upper surface of the base 31. A space for cable winding is formed between the base 31 and the annular portion 32. Two groups of limiting portions 33 are provided. The two groups of limiting portions 33 are respectively located on the outer side and the inner side of the cable winding space.

[0034] Preferably, the mounting plate 4 is composed of two arc-shaped plates matched with the lower surface of the fiber tray 3, and the above-mentioned holes are formed on the two arc-shaped plates, and are respectively fixed to the bottom plate 11 by fasteners. Furthermore, a first fastener 41 extending in the direction close to the fiber tray 3 is also provided on the two arc-shaped plates, and a first card slot matched with the first fastener 41 is formed on the fiber tray 3. Through the matching setting of the first fastener 41 and the first card slot, the fixing plate can be clamped and fixed to the fiber tray 3. Preferably, the first fasteners 41 formed on the two arc-shaped plates are symmetrically distributed on both sides of the fiber tray 3, so as to provide a more stable fixing effect for the fiber tray 3.

[0035] Two cable management rings 6 are provided and are respectively located on both sides of the fiber collection tray 3, for bundling cables to improve the neatness of cable arrangement inside the box body 1. The cable management ring 6 includes a connecting plate 61 arranged parallel to the bottom plate 11, and a first cable management portion 62 and a second cable management portion 63 integrally formed on the connecting plate 61. The first cable management portion 62 and the second cable management portion 63 are arranged opposite to each other and form a space for accommodating the bundled cables.
