Description

Technical Field

[0001] This utility model relates to the technical field of optical cable junction boxes, specifically a mirror-mounted optical cable junction box. Background Technology

[0002] Optical cable junction boxes are available in single-sided or double-sided structures. Existing double-sided optical cable junction boxes have the same distribution of operating surfaces, with the splicing and wiring area on the left side of one operating surface and the right side on the other. The functional areas on both sides of the box are staggered. After the trunk optical cable and distribution optical cable enter the box, they are stripped and fixed in the optical cable fixing area for activation. Typical trunk and distribution optical cables have 48, 72, 144, 192, 288, or more cores. Unused optical fibers are usually connected by direct fusion splicing and then sent to the optical cable junction box of the next node for use. However, the remaining optical fibers with fewer cores are stored in the optical cable junction box, resulting in a lot of waste. Moreover, it is inconvenient to communicate with the other side with unused optical fibers. The staggered arrangement can easily cause fiber breakage during communication and also requires increasing the length of the communication cable, increasing the cost of optical fibers. Therefore, a mirror-mounted optical cable junction box is proposed. Utility Model Content

[0003] The main purpose of this utility model is to provide a solution that can effectively address the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a mirror-mounted optical cable junction box, including a chassis, the chassis having a double-sided structure, and front and rear doors rotatably connected to the chassis, characterized in that: it further includes an A operating surface disposed inside the chassis and a B operating surface mirror-disposed to the A operating surface, and several interconnected fiber routing areas are provided between the A operating surface and the B operating surface.

[0005] Preferably, both the A and B operation surfaces are provided with an optical cable fixing area, an optical cable splicing and wiring area, a fiber optic coiling area, and an optical splitter area.

[0006] Preferably, the chassis is equipped with several cable management devices.

[0007] Preferably, the fiber-carrying area is provided with a plurality of fiber-passing holes.

[0008] Preferably, a fiber conveying tube is provided between the fiber conveying holes on the A operating surface and the fiber conveying holes on the B operating surface.

[0009] This invention has the following advantages: By mirroring the A and B operation surfaces and providing an interconnected fiber routing area between them, unused stripped or spliced ​​optical fibers can be used interchangeably through the fiber routing area. This allows optical fibers from the A operation surface to reach the B operation surface, or vice versa, with a shorter fiber routing path. The dedicated fiber routing area also protects the optical fibers from breakage during interconnection, improving fiber utilization and reducing costs. Attached Figure Description

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figure 1-3 As shown, a mirror-mounted optical cable junction box includes a chassis 1, which is a double-sided structure with doors 2 rotatably connected to the front and rear of the chassis 1. The chassis 1 is characterized by having an A operating surface 3 and a B operating surface 4 mirror-mounted to the A operating surface 3. Several interconnected fiber routing areas 5 are provided between the A operating surface 3 and the B operating surface 4. The mirror-mounted A operating surface 3 and the interconnected fiber routing areas 5 facilitate the use of unused stripped or spliced ​​optical fibers through these areas. This allows optical fibers from the A operating surface 3 to reach the B operating surface 4 via the fiber routing areas 5, or vice versa, with a shorter fiber routing path. The dedicated fiber routing areas 5 protect the optical fibers from breakage during interconnection, improving fiber utilization and reducing costs.

[0016] In one embodiment, both the A operating surface 3 and the B operating surface 4 are provided with an optical cable fixing area 31, an optical cable splicing and wiring area 32, a fiber optic coiling area 33, and an optical splitter area 34.

[0017] In one embodiment, the chassis 1 is provided with a plurality of cable management devices 6.

[0018] In one embodiment, the fiber routing area 5 is provided with a plurality of fiber passage holes 51; and a fiber passage tube 52 is provided between the fiber passage holes 51 on the A operating surface 3 and the fiber passage holes 51 on the B operating surface 4 to facilitate fiber optic communication; to protect the fiber optic cable from being broken during transit.

[0019] When using this invention, after the optical cable enters the housing 1, the optical cable is first stripped and fixed in the optical cable fixing area 31. Then, the stripped trunk optical cable and distribution optical cable are spliced ​​and wired in the optical fiber splicing and wiring area. Unused stripped optical fibers can be passed through the fiber through hole 51 on the fiber through area 5 and used by the fiber through tube 52 to pass the optical fiber to the other side. The spliced ​​optical fiber can also be connected to the splitter in the optical splitter area 34. After the trunk optical cable is spliced, it is connected to the input end of the optical splitter. After the optical fiber is spliced, it is connected to the output end of the optical splitter to achieve optical splitting. The excess fiber in the connection can be wound in the excess fiber coiling area 33. If there is any excess fiber in the optical fiber splicing distribution area 32, it can also be used by the opposite operation surface through the fiber tube 52. That is, the unused optical fiber of operation surface A 3 passes through the fiber tube 52 to operation surface B 4 and is used on operation surface B 4; or the unused optical fiber of operation surface B 4 passes through the fiber tube 52 to operation surface A 3 and is used on operation surface A 3.

[0020] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
