Description
Technical Field
The application relates to the technical field of optical cables, in particular to a modularized optical cable assembly and a networking topological structure.
Background
With the development of 5G communication and internet of things, more and more 5G antennas or devices need to be accessed by optical fibers, such as a 5G antenna installed on a smart lamp post and a vehicle antenna installed on a railway vehicle. In a normal case, when an optical fiber is accessed, 1 optical cable with 1 core or multiple cores is laid for each access point for accessing, which is specifically as follows:
(1) As shown in fig. 1, for a rail vehicle in-car antenna fiber access scenario, it is common to pull the fiber 40 from the BBU (Building Base band Unit, baseband processing unit) at the head or tail of the car to the PRRU (Pico Remote Radio Unit, remote radio unit) in a different car.
(2) As shown in fig. 2, the 5G antenna fiber access scenario for smart poles is typically pulling the fiber 40 from the nearest cable convergence point 7 (e.g., a cable junction box) to a different pole.
For a fiber access scenario like this (where there are multiple terminal devices along the line that need to be accessed from the same cable convergence point), the conventional fiber lay mode of pulling individual fibers from the cable convergence point to each terminal device has the following drawbacks:
(1) More optical fiber materials are generally required, and the lengths of each device from the optical cable convergence point are different, so that various materials are required, and the site construction and management are inconvenient.
(2) The network can not be built quickly, each terminal equipment needs to be laid from an optical cable convergence point, the problem of repeated laying of optical cables exists, and the construction efficiency is low.
(3) In addition, in the railway vehicle scenario, the railway vehicle usually needs to be checked and maintained regularly, each carriage needs to be disassembled and maintained and then recombined, and the carriages are rearranged in order during the recombination, in this case, the optical cables in the carriages need to be replaced and networked again. This results in a significant cost investment and time waste.

Referring to fig. 3 and 4, an embodiment of the present application provides a modular optical cable assembly, which includes a first main connection end 1, a second main connection end 2, a first branch connection end 3 and an optical cable 4, wherein the first main connection end 1 has a plurality of first ports 10, the second main connection end 2 has a plurality of second ports 20 corresponding to the first ports 10 one by one, the first main connection end 1 and the second main connection end 2 can be butted with an optical cable convergence point 7, the second main connection end 2 can be butted with the first main connection end 1 of another modular optical cable assembly, and the first branch connection end 3 has at least one third port 30; the optical cable 4 has a plurality of optical fibers 40 therein, wherein the optical fibers 40 are connected according to the following rule:
each first port 10 is numbered according to a set sequence, each first port 10 is butted with one optical fiber 40, wherein the other ends of the optical fibers 40 corresponding to the first ports 10 numbered at the forefront are butted with the third ports 30 one by one, and the other ends of the optical fibers 40 corresponding to the rest first ports 10 are butted with the second ports 20 sequentially from the first second ports 20.
Specifically, the principle of the application is as follows:
as shown in fig. 3 and 4, the first ports 10 are numbered in the order of the settings, and are numbered A1, A2, A3, & gt, a12, & gt, since the second ports 20 are in one-to-one correspondence with the first ports 10, the second ports 20 corresponding to A1 can be numbered B1, the second ports 20 corresponding to A2 can be numbered B2, and so on, and the numbers B1, B2, B3, & gt, B12, & gt of the second ports 20 are obtained, and the optical fibers 40 connected with A1, A2, A3, & gt, a12 are numbered F1, F2, F3, & gt, F12, & gt, and the third ports 30 are numbered C1, C2..
When the optical fibers 40 in the optical cable 4 are connected, one optical fiber 40 is connected respectively A1, A2, A3, a12, and meanwhile, as shown in fig. 4, the two foremost optical fibers 40 (i.e. F1 and F2) are in butt joint with the two third ports 30 (i.e. C1 and C2) one by one, and when the other optical fibers 40 (i.e. F3, F12, and a) are connected with the second port 20, the connection of the optical fibers 40 is completed in a staggered connection mode, i.e. from the first second port 20 (i.e. B1), F3 is connected with B1, F4 is connected with B2, F12 is connected with B10, and so on.
Referring to fig. 5 and 6, for example, a rail vehicle having a plurality of carriages arranged in sequence, each carriage having a terminal device 6, the terminal device 6 being a PRRU, a cable convergence point 7 being provided in the head of the vehicle when networking is performed, the cable convergence point 7 being a BBU, one modular cable assembly being arranged in each carriage, the first branch connection end 3 of the modular cable assembly in each carriage being connected to the PRRU in the carriage, the first main connection end 1 of the modular cable assembly in the first carriage being in abutment with the BBU, the first main connection end 1 of each modular cable assembly in the rear being in abutment with the second main connection end 2 of the preceding modular cable assembly, and obviously A1 being in abutment with B1, A2 being in abutment with B2, A3 being in abutment with B3, and so on.
Referring to fig. 5 and 6, it can be found that, in the above-mentioned networking topology structure, the optical fiber connection form in each carriage is the same, and even if the sequence of each carriage is exchanged, the link topology structure is not affected, and the optical fiber access of each terminal device is not affected, so that the problem that the optical cable needs to be replaced again to build the network due to the disturbance of the laying position can be avoided.
In the networking topological structure, the optical cable assemblies used in each carriage are identical, namely only one material exists, so that maintenance, management and construction costs can be reduced.
In the networking topological structure, the optical cable assemblies used in each carriage are connected in sequence, and the optical cable is not repeatedly laid on the laying path, so that the construction cost can be reduced, and the construction efficiency is improved.
It should be noted that, the first ports 10 of the actual first main connection terminal 1 are generally arranged regularly in one or more rows, such as in fig. 6, but the irregular arrangement is not excluded, and whether or not the first ports 10 are arranged regularly, the above-mentioned setting sequence refers to that all the first ports 10 are numbered sequentially, so that the optical fibers 40 corresponding to the first ports 10 with the first numbers can be butted with the third ports 30.
The above-mentioned setting sequence is not limited by the actual physical location of the first ports 10, for example, the first ports 10 in a row of the rule in fig. 6 may be numbered in the sequence from top to bottom in fig. 6, may be numbered from the middle in fig. 7, or may be numbered in the mode of no law in fig. 8, and although the numbering modes are different, the purpose of the present application can be achieved by only connecting the optical fibers 40 in the rule described above, and the different numbering modes only affect that the optical fibers 40 may cross each other in space, so that the numbering may be performed in the sequence in fig. 6 in order to avoid the optical fiber disorder.
In some preferred embodiments, the first branch connection ends 3 have a plurality, the optical fibers 40 corresponding to the first ports 10 numbered at the forefront are divided into a plurality of first optical fiber groups corresponding to the first branch connection ends 3 one by one, and the other ends of the optical fibers 40 included in the first optical fiber groups are in butt joint with the third ports 30 of the corresponding first branch connection ends 3 one by one.

As shown in fig. 11 and 12, it can be found that, in the case of having two first branch connection ends 3, in the networking topology structure, the optical fiber connection form in each carriage is the same, even if the sequence of each carriage is exchanged, the link topology structure is not affected, and the optical fiber access of each terminal device is not affected, so that the problem that the optical cable needs to be replaced again to build the network due to the fact that the laying position is disturbed can be avoided by adding the first branch connection ends 3.
In some preferred embodiments, when the first optical fiber group includes a plurality of optical fibers 40, the first port 10 corresponding to each optical fiber 40 is numbered consecutively, and as an example, there are two first optical fiber groups, each first optical fiber group includes 2 optical fibers 40, and then 2 optical fibers 40 in one first optical fiber group are numbered F1 and F3, and the other optical fibers are numbered F2 and F4.
Or the first port 10 corresponding to each optical fiber 40 is numbered discontinuously, for example, two first optical fiber groups each contain 3 optical fibers 40, and then the 3 optical fibers 40 in one first optical fiber group are numbered as F1, F3 and F4, and the other is numbered as F2, F5 and F6.
Or a part of the numbers of the first ports 10 corresponding to the optical fibers 40 are continuous numbers, and the other part is discontinuous numbers, and as an example, two first optical fiber groups are provided, and each first optical fiber group contains 3 optical fibers 40, then the 3 optical fibers 40 in one first optical fiber group are numbered as F1, F3 and F4, and the other numbers are F2, F5 and F6.

In this embodiment, the fourth port 50 of the second branch connection terminal 5 may be numbered as D1, D2.. Since the optical fibers 40 connected to the first ports 10 are connected to the first branch connection terminal 3 and the optical fibers 40 connected to the remaining first ports 10 are connected to the second ports 20 in a staggered manner, the second ports 20 are not connected to each other, such as B11 and B12, and the second ports 20 are butted to the fourth port 50 of the second branch connection terminal 5 through the optical fibers 40 (i.e., F13 and F14), as shown in fig. 15 and fig. 16, so that the bidirectional signal input of the link after the networking can be realized.

It can be found that in the networking topology structure, the optical fiber connection form in each communication area 8 is the same, and even if the order of each communication area 8 is changed, the link topology structure is not affected, and the optical fiber access of each terminal device is not affected, so that the problem that the optical cable needs to be replaced again to build the network due to the disorder of the laying position can be avoided.
