Description

Technical Field

[0001] The invention relates to an outdoor integrated fusion, distribution and splitting box, belonging to the technical field of optical communication equipment. Background Art

[0002] Fiber optic splitter boxes, as access points close to user premises, are crucial optical access point equipment in the Optical Distribution Network (ODN). They connect distribution cables to butterfly cables entering homes, performing fiber optic splicing, splicing, and splitting within the box. However, the existing ODN network is 20 years old, and much of the access network equipment has suffered damage due to age or a combination of accidents. In particular, older equipment is no longer able to meet new requirements and has poor environmental adaptability.

[0003] Outdoor integrated fusion, distribution, and splitter boxes for access networks serve as outdoor optical cable distribution systems. They provide termination and patching for trunk and user distribution cables. After the optical cables are introduced into the box, they are secured, terminated, and patched. Patch cables are then used to connect the trunk and user cables. The box typically houses a splice tray and an optical splitter. After the trunk cables are stripped and secured inside the box, the stripped bare fibers are spliced ​​at the splice tray to the patch cables stored inside. One end of the patch cable plugs into the splitter's input port, while the pigtails inside the box plug into the splitter's output port. The other end is mounted on an adapter at the bottom of the box. During on-site installation, the user cable connectors are mounted on the adapter, ensuring optical continuity and improving installation efficiency. However, since most optical cables are typically installed outside the box, the splice points cannot be stabilized if subjected to external forces. Accidents and other factors can cause the connectors to loosen or even break, leading to communication interruptions. Furthermore, since there are relatively more network connections inside the box, the probability of failure points increases, resulting in reduced network stability and reliability. Summary of the Invention
