Description

Technical Field

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

[0002] As an access point close to the user end, the fiber optic cable splitter box is an important optical access point device in the ODN (optical distribution network). It is used to connect the distribution cable with the butterfly cable entering the home to achieve terminal connection, and complete the fusion, digging and splitting functions of the optical cable in the box. However, the existing ODN network has been built for 20 years, and many access network devices have been damaged due to long service time or accidental reasons. In particular, the functions of the previous equipment cannot meet the new needs and have poor environmental adaptability.

[0003] The outdoor fusion distribution and splitting integrated box used for access network is an outdoor optical cable distribution product. It is a handover equipment for the trunk optical cable and the user distribution optical cable to provide optical cable termination and jumper connection. After the optical cable is introduced into the optical cable handover box, it is fixed, terminated, and fiber-matched, and then the trunk optical cable and the user optical cable are connected by using jumpers. Usually, the box is equipped with a fusion tray and an optical splitter. After the trunk optical cable enters the box and is stripped and fixed in the box, the stripped bare fiber is fused with the jumper stored in the box at the fusion tray. One end of the jumper is plugged into the input port of the optical splitter, and one end of the pigtail in the box is plugged into the output port of the optical splitter, and the other end is installed on the adapter seat at the bottom of the box. During on-site installation, the connector jack of the user optical cable is installed on the adapter seat to achieve the conduction of the optical path and improve the construction efficiency. However, since most optical cables are usually set outside the box, once they are subjected to external force, it is impossible to ensure the stable force of the fusion point, and the loosening or even damage of the connector due to accidents and other comprehensive reasons will lead to communication interruption. Furthermore, since there are relatively more network connections in the box, the probability of failure points increases, resulting in reduced network stability and reliability.
