Embodiment approach

[0040] An embodiment of the multi-core plastic optical fiber provided by the present invention is as follows:

[0041] A multi-core plastic optical fiber includes a solid cladding, a plurality of plastic optical fiber cores and a mark for identifying the relative position of the plastic optical fiber core. The refractive index of the cladding is less than that of the plastic optical fiber core. All plastic optical fiber cores are located inside the cladding, extend radially along the cladding, and penetrate the cladding. The distance between the cores of the plastic optical fiber is between 2um and 20000um, identification mark Extend parallel to the plastic optical fiber core.

[0043] A multi-core plastic optical fiber includes a cladding, a plurality of plastic optical fiber cores, a plurality of hollow holes and a mark for identifying the relative position of the ...

Embodiment approach

[0053] An embodiment of the plastic optical fiber optical cable provided by the present invention is:

[0054] A plastic optical fiber cable, including one or more cable cores, one or more sheaths and a sheath. All cable cores and sheaths are in a one-to-one correspondence. Each cable core and the corresponding sheath form one Concentric cable, that is, the periphery of the cable core is surrounded by a sheath, and all the sheaths are circumferentially distributed in the outer sheath, that is, the outer sheath radially surrounds all the sheaths and the inner cable core, forming a cylindrical multi-core optical cable. In the specific implementation of this solution, a protective layer can be added between the cable core and the sheath, and the cable core can be a multi-core plastic optical fiber.

[0055] In the above embodiment, when the number of cable cores is one, the outer sheath and the sheath are combined into one, that is, the plastic optical fiber cable only includes a cabl...

Abstract

The invention relates to multi-core optical fibers and cables, and provides several kinds of multi-core plastic optical fibers and a plastic optical fiber cable with the multi-core plastic optical fibers as cable cores. Manufacturing cost of the plastic optical fibers is further reduced, the communication rate of the plastic optical fibers is improved exponentially, and orderliness and attractiveness of wiring the plastic optical fibers at a public place are achieved. Each optical fiber is composed of a fiber core and a cladding, each cladding is lower than the corresponding fiber core in refractive index, total reflection of light is generated on a critical plane from the fiber cores to the claddings, and therefore the light is maintained in the fiber cores; the optical fibers are wrapped by several layers of protection structures before being used, a wrapped cable is called as an optical cable, and the optical cable comprises the optical fibers, a protection layer and a sheath.

Description

Technical field [0001] The invention relates to the field of multi-core communication cables. Background technique [0002] With the in-depth exploration of the optical field in modern science, optical fiber communication has entered people's field of vision. The optical fibers currently used for communication can be divided into quartz optical fibers and plastic optical fibers according to the materials used. [0003] Quartz optical fiber has high requirements for the use environment, and it is not easy to install and connect. Quartz optical fiber overcomes the shortcomings of copper cable and other traditional communication methods such as severe electromagnetic interference and large radiation. However, its texture is brittle, its mechanical strength is poor, and the bending radius of the optical cable is large. It has high requirements for the application environment; The precision of the connection is high, the branching and coupling are not flexible, and the installation and...
