Special optical fiber ribbon cable for communication

Abstract

The invention discloses a special optical fiber ribbon cable for communication and belongs to the technical field of optical cables. The optical fiber ribbon cable is composed of a plurality of optical cable units, wherein the appearances of the optical cable units are flat, grooves are formed in connecting positions, tearing ropes are arranged in the grooves, an optical fiber ribbon coated with a loose sleeve is arranged at the center of each optical cable unit, reinforcing pieces are arranged on the two sides of each loose sleeve, and the outermost layer of each optical cable unit is an outer protective layer. An optical fiber is bent and insensitive and has excellent transmission performance and good bending resistance; the reinforcing pieces are non-metallic waterproof reinforcing pieces and meet the requirements for thunder prevention, high strength and high water resistance; the optical fiber ribbons, the loose sleeves and the outer protective layers are all made of transparent materials, and therefore after construction is carried out at a decorated place, the effects of transparency, invisibility and uniformity with the environment can be achieved. Filling of oil is not needed, so that the problem of environmental pollution in the construction process is solved. The optical cable units are connected through the grooves easy to separate, and the tearing ropes are arranged in the grooves, so that convenience is brought to users in wiring and construction.

Description

technical field

[0001] The invention belongs to the technical field of optical cables, in particular to an optical fiber ribbon optical cable for special communication. Background technique

[0002] FTTX quickly set off a global boom because of its many advantages in broadband access. With the country's vigorous promotion of FTTX, fiber-to-the-home and fiber-to-the-desktop have become an inevitable trend. However, some problems were encountered during the implementation of the project, requiring non-destructive installation of special environments such as original buildings, meeting rooms, comprehensive office areas, and cultural relics protection, without destroying the wall decoration, and coordinating the beautification effect with the original wall. . At the same time, the ointment filling in the optical cable is also very easy to cause pollution to the site during construction, destroying the cleanliness of the decoration.

[0018] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0019] figure 1 It is a schematic cross-sectional structure diagram of a special optical fiber ribbon cable for communication. An optical fiber ribbon optical cable for special communication is composed of several optical cable units. The tube 3 covers the optical fiber ribbon, the loose tube 6 is provided with reinforcements 4 on both sides, and the outermost layer of the optical cable unit is an outer sheath 5 . The optical fiber unit in this embodiment is flat in shape, and there are grooves at the joints of the four optical fiber units, and the tear rope 6 is used in the groove to facilitate separation during construction.
