摘要： An optical distribution frame cabinet (200) is provided, including a cabinet (201), where a plurality of optical distribution frames (202) are installed in the cabinet (201). A first end of the optical distribution frame (202) is hinged to the cabinet (201), and a sliding groove (504) is concavely disposed on an end face of a second end of the optical distribution frame (202). A mounting ear component (505) is disposed on an end face of the cabinet (201). The mounting ear component (505) is convexly disposed facing the optical distribution frame (202), and when the mounting ear component (505) is inserted into the sliding groove (504), the mounting ear component (505) slides in a guide direction of the sliding groove (504) until the optical distribution frame (202) is installed into the cabinet (201). According to the optical distribution frame (202), the sliding groove (504) having an inclined surface feature is disposed to cooperate with the mounting ear component (505) of the optical distribution frame cabinet (200), thereby effectively avoiding a phenomenon of local downward inclination in the process of installing the optical distribution frame, and improving efficiency of installing the optical distribution frame.

摘要： The present invention provides an optical splitting apparatus. The optical splitting apparatus includes an enclosure and an even optical splitter and an uneven optical splitter that are disposed in the enclosure. A light inlet and a plurality of light outlets are disposed on the enclosure, and fiber adapters are disposed on the light outlets. The light inlet, the even optical splitter, the uneven optical splitter, and the light outlets are connected, so that optical paths are formed between the light inlet and the light outlets by using the even optical splitter and the uneven optical splitter. The light inlet is connected to at least one of a light input end of the even optical splitter and a light input end of the uneven optical splitter, and the fiber adapter on the light outlet is connected to at least one of a light output end of the even optical splitter and a light output end of the uneven optical splitter. This type of optical splitting apparatus may be used in coordination with an optical cable that has an optical fiber connector at an end, so that output optical power of each light outlet can be configured flexibly based on a user distribution status while plug-and-play is implemented. In this way, not only a long coverage distance is implemented, but also no optical signal resources are wasted and as many users as possible are covered.

摘要： This application provides a connection structure and an optical cable connection box. The connection structure includes a splicing region and a fiber management region that are disposed with a distance therebetween along a circumferential direction of the connection structure, where a fiber routing path passing through the connection structure in the splicing region and the connection structure in the fiber management region is further disposed in the connection structure, so that an optical fiber extends into the fiber management region for storage through the fiber routing path from the splicing region, and a redundant optical fiber can be transferred from the original splicing region to the fiber management region for storage. In this way, space of the connection structure can be effectively used, thereby reducing space occupied by the connection structure.

摘要： This application discloses a drawer-like assembly, a subrack, and an optical splitter box, and pertains to the field of signal transmission. The drawer-like assembly includes a tray, two slide rails, two slide rail supports, and a synchronous drive mechanism. The tray is configured to dispose cables. Each of the two slide rails includes a sliding channel, and a clamping part and a bearing part that are located on two opposite sides of the sliding channel. Each clamping part is clamped to one slide rail support, and the bearing part is configured to support the tray. The synchronous drive mechanism includes a first drive part disposed in the slide rail support, a second drive part disposed in the slide rail, and a third drive part disposed in the tray. When the tray is under an external effect, the tray, the slide rail, and the slide rail support can move relative to each other with cooperation of the first drive part, the second drive part, and the third drive part. When the cables are disposed in the drawer-like assembly, redundant cables are located inside the drawer-like assembly, to effectively avoid disorder of the redundant cables outside the drawer-like assembly.
