Problems solved by technology

[0006] In view of the above defects or improvement needs of the prior art, the present invention provides a tight-buffered optical fiber and a method for making a tight-buffered optical fiber. The purpose is to arrange a separation layer between the fiber body and the tight-buffered layer, and the separation layer is made of a special material Made, the separation layer acts as a separating agent and lubricant between the fiber body and the tight sleeve layer, making the tight sleeve layer easy to separate and slip relative to the fiber body, reducing the peeling force, avoiding damage to the fiber body, and improving Product performance, thus solving the problem that the current tight sleeve coating has strong adhesion to the surface of the optical fiber, which requires a large force to peel off the tight sleeve coating, which causes certain difficulties for reprocessing. Moreover, in the stripping process, it is easy to Technical problems that damage the fiber body and affect product performance

Embodiment 1

[0036] At present, the tight sleeve layer is generally made of materials such as TPEE (thermoplastic polyester elastomer) or PA12 (nylon 12). Due to the characteristics of materials such as TPEE and PA12, they have strong adhesion to the surface of the optical fiber and require a large The intensity of stripping the tight sleeve layer will cause certain difficulties for reprocessing. Moreover, in the process of stripping, the fiber body will be easily damaged, which will affect the product performance.

[0037] In order to solve the foregoing problems, the present embodiment provides a tight sleeve optical fiber, which is combined below figure 1 and figure 2 , to specifically illustrate one of the realizable manners of the tight-buffered optical fiber of this embodiment. in, figure 1 In order to facilitate the display of the positional relationship between different layers, the tight-buffered fiber is partially stripped.

[0038] The tight-buffered optical fiber of this em...

Embodiment 2

[0052] The present invention also provides a method for manufacturing a tight-buffered optical fiber, which is suitable for the tight-buffered optical fiber in the first embodiment above.

[0053] Combine below Figure 4 and Figure 5 , to specifically illustrate one of the realizable ways of the method for manufacturing the tight-buffered optical fiber of this embodiment. The manufacturing method of the tight-buffered optical fiber comprises the following steps:

[0054] Step 401: Use a coating device to coat a separation layer on the surface of the optical fiber body, wherein a predetermined separation agent is contained in the coating device.

[0055] Wherein, the optical fiber body includes a core, a cladding and a coating layer, the cladding is arranged on the periphery of the fiber core, the coating is arranged on the periphery of the cladding, and the separation layer is coated on the surface of the coating. The optical fiber body may be prefabricated, or prepurchas...

Abstract

The invention discloses a tight-buffered optical fiber and a making method thereof. The tight-buffered optical fiber comprises an optical fiber body, a separation layer and a tight buffer layer; the surface of the optical fiber body is coated with the separation layer, and the tight buffer layer is disposed on the periphery of the separation layer; the separation layer is used for spacing the optical fiber body from the tight buffer layer to avoid adhesion between the tight buffer layer and the optical fiber body. The separation layer made of a special material is disposed between the opticalfiber body and the tight buffer layer to serve as a separating agent and a lubricating agent between the optical fiber body and the tight buffer layer, so that the tight buffer layer is easy to separate and slide relative to the optical fiber body, the peeling force is reduced, damage to the optical fiber body is avoided, and the product performance is improved.

Description

technical field [0001] The invention belongs to the field of optical fiber technology, and more specifically relates to a tight-buffered optical fiber and a method for manufacturing the tight-buffered optical fiber. Background technique [0002] At present, the rapid development of fiber-to-the-home technology has given birth to the rapid expansion of the indoor optical cable industry. In addition to the traditional operators of indoor optical cable products, non-operator markets such as communication equipment manufacturers, military and sensing products are also developing rapidly. [0003] The demand for products of this type of users is mainly optical cable products based on tight-buffered optical fibers. During the use of tight-buffered optical fiber products, the tight-buffered coating must be stripped off. In order to ensure the quality of the tight-buffered fiber and at the same time facilitate the use, the peeling force of the tight-buffered coating of the tight-b...
