Greentel Fiber Optic Splice Closure adopts two kinds of advanced splice and crimp connection methods. The splice card is connected, the core wire is automatically stripped and automatically stripped, and the excess threads are automatically cut off. The contact is not exposed and the splice is quick, convenient, and reliable. Inside the fiber optic splice closure is the end of the optical fiber cable. The role of the fiber cable splice is to bring together two or more computer room signals that are not connected together, and then use pigtails to connect the two unconnected optical cables as required. The fiber jumper inside the fiber optic splice closure is connected to the external fiber through an adapter. Usually the adapter is a ceramic die, and care must be taken when inserting or pulling the fiber head. Be careful not to use too much force, otherwise it may squash or crush the ceramic sleeve, causing the cable distribution box to fail to transmit signals properly. Optical fiber relay box power supply and installation environment, installation of fiber optic splice closure to do a good job of on-site protection measures, moisture, water, dust, and pay attention to the actual operation of the scene. The device consumes a lot of power and has a high internal temperature. When it is used in a high temperature environment, especially when it is used outside in summer, it can easily accelerate the aging of the device or even damage it. In the continuous operation of the monitoring equipment, the change of the power supply is normal. If the equipment requires a very narrow input range, it is inevitable that the equipment will not work or even cause damage when the power supply changes. With the increasingly fierce competition in the telecom market, operators are stepping up their own fiber-optic cable networks. Although the fiber optic splice closures have disadvantages in terms of material properties, integrated structure of fusion-splicing fibers, and capability of adapting fusion splice trays to various types of core structures, in the next few years, the large-scale construction of optical fiber access networks has not been transferred. Today's box replacement products will still be used in a large number of applications, so fiber optic splice closures will have a good market prospect.
