The cable splice box, also called fiber optic splice closure and barrel, is suitable for direct and branch connection of overhead cables, pipelines, and direct burial methods for various structural optical cables. The box body adopts imported reinforced plastics, which has high strength and corrosion resistance. The terminal is suitable for the connection in the terminal room of the structure optical cable, the structure is mature, the sealing is reliable, and the construction is convenient.
With the increasing popularity of fiber optic cable networks, fiber optic splice closures that provide reliable connectors for fiber optic cables are becoming known and familiar to everyone. There are a wide variety of fiber optic splice closures available in the market. The new name of the fiber optic splice closure is the optical fiber splice box, which is a passive device that provides reliable guarantee for the continuity of the optical cable.
It is divided into overhead, pipelines and direct burial in the occasion of use; the internal connection mode is divided into straight connection and split connection. The former is to connect two optical cables with the same number of cores, and the latter is to separate one large number of optical cables and one or more small number of optical cables to connect or multiple optical cables to each other. Backbone network is generally dominated by straight-through mode.
The access layer is mainly divided. The connection between optical fibers is divided into mechanical connection and heat-shrinkage connection. The former uses mechanical connectors to mechanically break and pass the optical fibers that need to be connected. The concentricity of the connectors aligns the cores, which use a fusion splicer to thermally fuse together the fibers that need to be connected and secured and protected by a heat-shrinkable sleeve. Since the latter produces little additional attenuation and has a small impact on the entire network, most of the current use of heat-shrinking connections increases the concentricity of the network.
GreenTel provides various shapes Inline Closure. All the closures we offered are with a great sealing performance. High quality plastic material also ensures the durability whether the closure is in air, in pipeline or buried underground.
