The cable connection box is a connection protection device that provides continuity of optical, sealing and mechanical strength between adjacent optical cables. It is mainly suitable for straight-through and branch connections of overhead, pipeline, direct buried and other laying methods of various structural optical cables. As an important device for information transmission, in which fields does the cable joint box play a role?This article will introduce you in detail.
In telecommunications and communication networks, cable connection box is the basic equipment for building backbone networks, metropolitan area networks, and access networks. In terms of backbone communication networks, long-distance optical cable transmission lines need to be connected in segments through a cable joint box. Through a precise protection structure, the cable joint box controls the connection loss of single-mode optical fiber below 0.1dB to ensure the long-distance uninterrupted transmission of data, which can support the stable operation of the national trunk communication network. In the construction of metropolitan area networks, the cable joint box is used to realize the connection between the trunk optical cable and the convergence optical cable, as well as the transfer of different routing optical cables, which can meet the communication needs of high-density users in urban areas. In the fiber-to-the-home access network project, the cable joint box can realize the branch connection of one trunk optical cable to multiple home optical cables. Through the optical fiber management structure, the insertion loss of each branch port is stable, and it provides home users with Gigabit broadband access capabilities.
Radio and television networks have high requirements for the stability and fidelity of signal transmission. Cable connection box is mainly used for the maintenance of the transmission link of radio and television signals in this field. In the trunk transmission section from the front-end computer room to the sub-front-end, the cable joint box can prevent the intrusion of water vapor through a sealed structure, prevent the signal attenuation of the optical fiber connector due to moisture, and ensure the stable transmission of high-definition TV signals. In a cable TV distribution network, the cable joint box can distribute signals from the optical node to the optical receiver of each cell. The optical fiber containment structure inside the cable joint box can realize the orderly coiling of excess optical fibers, reduce the signal loss caused by excessive bending of the optical fibers, and allow the client to receive high-quality signals.
The construction of the smart grid has made the power communication network put forward strict requirements for the high voltage and electromagnetic interference resistance of the cable joint box. In the transmission line, the connection of the OPGW optical cable requires the use of a connector box with a grounding function, and the internal sealing structure must also be able to resist rain, dust and other erosion. In substation communication networks, cable connection boxes are often used to connect optical cable lines in different areas of the station, supporting real-time transmission of power dispatching data and equipment monitoring information.
Relying on its excellent performance, the cable connection box can realize the reliable connection and protection of optical fiber communication links in applications in different fields, and it is also an important protection device in information transmission networks in various industries.
