Problems solved by technology

[0003] However, among the optical splitters currently in the market, all of them have special-shaped structures, and there is a large angle between the branch ends, resulting in a large overall size, which is very unfavorable for the continuous operation of the buried plow during the construction process, which greatly increases the construction cost.
In addition, the current optical splitter is often designed for a single cable type, and the versatility is not high

Embodiment 1

[0057] see figure 1 and figure 2 As shown, the embodiment of the present invention provides a compact passive splitter, including a casing 1, a first branch end 2, a second branch end 3, and a third branch end 4; the casing 1 is provided with a Inner cavity 11 and outer cavity 12 under pressure. Each of the three branch ends includes a connection nut 26 , an optical fiber protection component 21 , an inner armor crimping component 22 , an insulating sealing component 23 , an armor protection component, a bending limiter 25 and a set screw 27 .

[0058] The first branch end 2 , the second branch end 3 , and the third branch end 4 are all inserted into the insertion hole 13 of the casing 1 and connected to the casing 1 through a connecting nut 26 . The first branch end 2 , the second branch end 3 , and the third branch end 4 are in a parallel state with each other, and the center lines are located on the same horizontal plane.

Embodiment 2

[0060] see figure 1 and Figure 7 As shown, on the basis of Embodiment 1, the casing 1 includes an inner cavity 11 for storing optical fibers, an outer cavity 12 for pressure-bearing, an insertion hole 13 and an optical fiber inlet 14. The insertion hole 13 is located at the end of the casing 1, and the outer cavity The body 12 is in the center of the housing 1 , and the inner cavity 11 surrounds the outer cavity 12 . After the first branch end 2 , the second branch end 3 , and the third branch end 4 are connected to the casing 1 , the optical fibers enter the interior of the casing 1 through the jack 13 , and enter the inner cavity 11 through the optical fiber inlet 14 for fusion storage. The electrical circuit also enters the interior of the housing 1 through the jack 13, and then enters the outer cavity 12 for interconnection and storage.

Embodiment 3

[0062] see figure 2 and image 3 As shown, on the basis of Embodiment 1 or 2, the armor protection assembly includes a conical locking mandrel 241, a first layer of steel wire spacers 242, an inner locking sleeve 243, a second layer of steel wire spacers 244, and an outer lock Tight sleeve 245 and preload nut 246.

[0063] The inside of the conical locking mandrel 241 is provided with a hole for passing through the optical cable 5, which is composed of an annular boss, a seat body, and a conical body. The inner locking sleeve 243 is provided with a hole through which the optical cable 5 passes, and is composed of a seat body and a cone body. The outer locking sleeve 245 is provided with a hole through which the optical cable 5 passes, the through hole has a tapered surface, and the outer side surface of the outer locking sleeve 245 has a stepped surface. The conical outer surfaces of the conical locking mandrel 241 and the inner locking sleeve 243 are both provided with th...

Abstract

The invention provides a compact passive splitter and an installation method, and belongs to the technical field of submarine optical cable communication systems, and the compact passive splitter comprises a housing and a branch end. An inner cavity used for storing optical fibers and an outer cavity used for storing electrical circuits are arranged in the shell, and jacks connected with the branch ends are arranged at the two ends of the shell. The branch end comprises a connecting nut, an optical fiber protection assembly, an inner armoring crimping assembly, an insulation sealing assembly and an armoring protection assembly. Through the design that the branch ends are in a parallel state, the disadvantage of a special-shaped structure of an original splitter is changed, no angle exists between the branch ends, and the boundary dimension of the splitter is greatly reduced. Therefore, continuous operation in the construction laying process is achieved, and the construction difficulty and time cost of plough burying operation are greatly reduced. In addition, an optimized steel wire crimping process is adopted, butt joint of most general cables can be achieved, and universality is high.

Description

technical field [0001] The invention relates to a compact passive splitter and an installation method, belonging to the technical field of submarine optical cable communication systems. Background technique [0002] With the rapid development of information technology, the submarine cable network has covered all the seas of the world, and has undertaken most of the communication of the backbone network. my country has vast seas, coastlines, and islands. In the interconnection system of multiple login sites and islands, the application of submarine optical splitters is particularly important. The submarine optical splitter is a submarine optical branching device, which can realize the communication between multiple sites of the submarine cable system, reduce the complexity of the system networking, and greatly improve the flexibility of the system scheduling. [0003] However, the current optical branchers in the market are all of special-shaped structures, and there is a la...
