Embodiment 1

[0038] Example 1: A single-core bidirectional plastic optical fiber system implementation scheme.

[0039] The single-core bidirectional plastic optical fiber system provided by the present invention is such as figure 1 As shown, it contains a perfluoroplastic optical fiber 101 and two plastic optical fiber connectors 100. The plastic optical fiber connector 100 is tightly fixed on both ends of the plastic optical fiber. The plastic optical fiber is connected with the optical fiber through the ferrule in the plastic optical fiber connector 100. Interface device. The perfluoroplastic optical fiber 101 selected in this embodiment belongs to a type of GI plastic optical fiber, and other GI plastic optical fibers can also be used in specific implementation.

Embodiment 2

[0054] Embodiment 2: An SC type plastic optical fiber connector.

[0055] The plastic optical fiber connector provided in this embodiment is an SC-type plastic optical fiber connector, as shown in Figure 5 (a) and Figure 5 (b). The main components are the extension cover 11, the ferrule 12, the spring 13, and the ferrule. The outer cover 14 and the sleeve 15 also include the SC cover 16 and the tail pipe 17. The SC cover 16 is provided with a plug-in switch, which can be used for positioning and limiting the relative position between the plastic optical fiber connector and the mating component. The ferrule 13 has a hollow structure with an outer diameter of 2.5mm and an inner hole diameter of 1.0mm, which ensures the convenience of inserting the perfluoroplastic optical fiber with an outer diameter of 0.5mm into the plastic optical fiber connector. The difference between the outer diameter of the plastic optical fiber and the inner aperture of the ferrule is too large, which ma...

Embodiment 3

[0077] Embodiment 3: An LC type plastic optical fiber connector.

[0078] The LC type plastic optical fiber connector provided by this embodiment, as shown in Figures 6(a) and 6(b), includes a protective cap 21, an LC shell 22, a spring 23, a ferrule 24, a ferrule cover 25, and a sleeve 26 and tail pipe 27. The ferrule 24 is a hollow structure, made of metal or plastic, with an outer diameter value of 1.25mm and an inner hole diameter of 1.0mm, which ensures the convenience of inserting a 0.5mm outer diameter perfluoroplastic optical fiber into a plastic optical fiber connector. At the same time, the difference between the outer diameter of the perfluoroplastic optical fiber and the inner aperture of the ferrule is not too large, which makes the connection between the plastic optical fiber connector and the perfluoroplastic optical fiber unstable.

[0079] Figure 6 (a) shows the assembly sequence of the LC-type plastic optical fiber connector, as follows:

Abstract

The invention provides a single-core two-way plastic optical fiber system which is long in transmission distance, convenient to install and low in cost, wherein the single-core two-way plastic optical fiber system solves the problems that an existing quartz optical fiber is not easy to install and maintain, an existing SI type plastic optical fiber is short in transmission distance and an existing GI type plastic optical fiber is high in cost. Meanwhile, the invention provides multiple types of plastic optical fiber connectors, wherein the problem that due to the fact that the diameter of the GI type plastic optical fiber is larger than the diameter of the quartz optical fiber and smaller than the diameter of an ordinary plastic optical fiber, the GI type plastic optical fiber can not be used in cooperation with an existing optical fiber connector is solved. The single-core two-way plastic optical fiber system comprises a single-core plastic optical fiber and two plastic optical fiber connectors, wherein the singe-core full duplex mode serves as the signal transmission mode of the single-core two-way plastic optical fiber system, the plastic optical fiber is a full-fluoroplastic optical fiber of the FONTEX type of the AGC and belongs to one type of GI type plastic optical fibers, and the two plastic optical fiber connectors are connected to the two ends of the plastic optical fiber respectively and can be replaced.

Description

Technical field [0001] The invention relates to the field of optical fiber communication and assembly, in particular to a plastic optical fiber communication method and various connectors. Background technique [0002] As the pioneer in the field of optical fiber communication, the installation cost of quartz optical fiber remains high. Quartz optical fiber overcomes the serious problem of electromagnetic interference in traditional communication methods, but it is very inconvenient to install and connect, and the cost is high. Quartz optical fiber has a brittle texture and poor mechanical strength. It requires certain tools, equipment and technology for installation and splicing; the core diameter is small, but the connection is not easy, and the branching and coupling are not flexible; the bending radius of the optical cable is large and easy to damage. These problems of quartz optical fiber not only increase the difficulty of implementing the optical fiber communication syste...
