[0034] Reference Figure 2 The module includes a housing 2, a connecting plate 3, a front cover 4, and a rear cover 5. The connecting plate 3 is installed in the middle of the housing 2 and forms an installation space 21 between it and the inner wall of the housing 2 for the MPO module box 7 to be inserted. The housing 2 has a front insertion and removal clearance area 22 and a rear insertion and removal clearance area 23 that are connected to the installation space 21. The MPO module can be inserted into the installation space 21 through the front insertion and removal clearance area 22 and the rear insertion and removal clearance area 23.

[0035] Reference Figure 1 The box body 2 has mounting ears 6 on its two outer side walls. The mounting ears 6 are connected to the box body 2 by the first bolt 63. The mounting ears 6 have a first mounting hole 61. One side of the first mounting hole 61 is connected to the lower end of the mounting ear 6 through a movable hole. The cabinet is rotatably mounted with screws. When connecting the box body 2 to the cabinet, the first mounting hole 61 of the mounting ear 6 is placed on the screw of the cabinet. Then the screw is rotated so that the mounting ear 6 is clamped between the head of the screw and the cabinet, thus completing the installation of the cabinet.

[0036] Reference Figure 2In this embodiment, the mounting ear 6 has a second mounting hole 62, and a second bolt is inserted into the second mounting hole 62 of two adjacent module boxes 1 to connect all the module boxes 1 into one piece, thereby increasing the stability of the module boxes 1 installed on the cabinet.
