The connection of the optical fiber in the fiber optic splice closure is mainly connected by the core portion of the optical cable being melted to the terminal portion, the direct melting type and the optical fiber core being fully melted to the terminal type. The connection of the core portion is completed by the fiber optic splice closure. The use of this connection method has certain difficulty, the investment is large, the network organization is called complex, which is conducive to the maintenance and management in the future, and is also highly flexible in the use process.
The quality inspection rules for the fiber optic splice closure of the optical cable are required to provide the electrical connection, grounding and disconnection of the metal components in the optical cable. We can understand this sentence, that is, the metal components of the whole network are connected to each other. Select a representative access point to ground. When there is strong electric penetration, you can enter the ground and protect the optical cable. Of course, this does not. Will cause damage to the equipment room.
If the metal components of the entire network are independent of each other and are disconnected, then each fiber optic splice closure must have at least one grounding point. When the divergence is connected, there must be more than one grounding point, and all of them should be grounded, so as to ensure the reliability of the strong electric power.
In fact, whether it is overhead, direct burial or pipeline is quite difficult to do, it brings a lot of work, and there is not much necessity. In actual work, the bureau is the first one. Ways to understand and operate. In this sense, it is valuable in terms of electrical performance that "after immersing the fiber optic splice closure for 24 hours, all metal parts in the box are connected by wires, and then the insulation and withstand voltage between them and the earth are detected."
