An ultra-thin diameter high-performance jumper optical cable

Abstract

The invention relates to a superfine-diameter high-performance special jumper wire optical cable, including an optical fiber and an outer sheath, and is characterized in that the periphery of the optical fiber is tightly wrapped by a nonmetal reinforcer, and the ultrathin outer sheath is extruded at the outermost layer. The superfine-diameter high-performance special jumper optical cable has the following beneficial effects: 1. the external diameter is small, the weight is light, the bending property is excellent, wiring space resources are greatly saved, and construction cost is reduced; 2. the flexible nonmetal reinforcing element and the high-performance ultrathin outer sheath are adopted, the optical cable has extremely good mechanical property and weather-resistant performance, when bearing relatively large tensile force and flattening force, the optical fiber does not break and is not damaged, thereby satisfying using demands of multiple fields of pipelines, short-distance overhead, jumper wire manufacture, machine rooms, medical treatment, aerospace, wind power industry, fiber-to-the-home and the like, and the optical cable is convenient to use and lay; and 3.an all-dry type structure is adopted, all units are arranged reasonably, and the superfine-diameter high-performance special jumper wire optical cable adapts to higher and higher requirements for the outer diameter dimension, high-temperature-resistant performance, bending raidus, tensile strength of the optical cable, particularly millions of times of hot plugging when used as a jumper wire optical cable and for ensuring signal transmission quality in a severe communication environment.

Description

Technical field [0001] The invention relates to an ultra-thin diameter high-performance jumper optical cable, in particular to a high-performance jumper optical cable with excellent tensile performance and weather resistance. Background technique [0002] In recent years, with the development of fiber optic communications in the direction of FTTB (Fiber to the Building), FTTO (Fiber to the Office), FTTH (Fiber to the Home), as well as the user’s preference for fiber to the room, fiber to the desktop, and fiber to the palm, etc. The requirements are getting higher and higher, and the plug-and-play jumper cable has been rapidly developed, and various optical cable manufacturers have also increased their investment in the research and development and production of jumper cables. However, most commonly used jumper cables are made of multiple aramid fibers wrapped around the tight-buffered optical fiber, and the outermost sheath material is extruded. This kind of optical cable can wi...

Problems solved by technology

However, this kind of optical cable also has some problems. First, when it is squeezed or bent during construction or use, it is easy to cause optical fiber breakage, which interrupts the transmission signal and brings troubles and losses to operators or end users; secondly, the optical cable When making jumper connectors, only the tight-buffered optical fiber is connected to the connector connector, and the tensile performance of the optical cable and the connector is poor. After repeated hot plugging, it is easy to cause the tight-buffered fiber to break and affect the service life of the optical cable; in addition, in wind power Field, medical, aerospace, military and other special fields have high requirements on the aging performance, weather resistance, oil resistance, and UV resistance of optical cables. The existing conventional jumper optical cables cannot meet the above requirements.

[0003] In view of the above-mentioned technical problems, there have been many kinds of jumper optical cables. For example, although the optical cable of Chinese patent 200820059871.0 has good tensile performance and flattening resistance, it can ensure that the optical fiber does not break when a large pressure is applied, but its Two inner and outer sheaths are set up, and the size is relatively large, which affects its wiring use in relatively narrow spaces such as indoors, computer rooms, and internal interconnection of communication equipment.

Another example is that although the optical cable described in Chinese patent 2010205003289.6 is small in size and has good bending performance, its tensile performance and weather resistance are poor, and it cannot meet the use requirements in harsh communication environments.
