288 core optical cable junction box It is used for outdoor waterproof optical handover box of equipment commonly used by China Telecom, China Mobile and China Unicom. The optical handover box is the equipment that realizes outdoor optical fiber wiring at the nodes of backbone optical cables and distribution optical cables in the outdoor optical cable access network, and can realize optical fiber Straight through , disk storage, and optical fiber fusion, scheduling functions. It can be installed outdoor on the ground or overhead.
The main features of 288 core optical cable junction box: according to its functions, it is divided into distribution area, backbone area, optical splitter area and idle pigtail management area. The wiring area has a capacity of 24 12 core preset pigtail distribution discs (melt storage unit) with a total of 288 cores, and the main trunk area has a capacity of 4 12 core preset end distribution discs (melt distribution integrated unit) with a total of 48 cores, and the use order is from left to right, from top to bottom.
Before 2000, a large number of local cable handover boxes were used in communication. Later, with the maturity of optical cable manufacturing technology, optical cables were more and more used in communication. In order to better access users, optical cable handover boxes were gradually used. In fact, the principle of the optical cable junction box is basically the same as that of the cable junction box. The optical cable junction box is a kind of junction equipment that provides the trunk layer optical cable and the distribution layer optical cable with optical cable termination and jumper. After the optical cable is introduced into the optical cable junction box, it is fixed, welded, and distributed, and then the optical fiber with transmission requirements is connected by jumper. Thus, it is very convenient to allocate and schedule optical cables. The optical cable junction box is a kind of passive equipment and cannot provide active transmission. For example, simply consider the optical cable junction box as an optical cable that can be repeatedly opened (adapter can be plugged in and pulled out for more than 500 times), can simply connect optical fibers, and can access more optical cables Connector Box.
