Loose tube ribbon optical cable

#This application claims priority to an application entitled “A Ribbon Optical Cable with a Loose Tube” filed in the Korean Industrial Property Office on Aug. 28, 2001 and assigned Serial No. 2001-51943, the contents of which are hereby incorporated by reference.

#1. Field of the Invention

#The present invention relates to ribbon optical cables. More particularly, the present invention relates to a ribbon optical cable with a loose tube.

#The foregoing and other object and features of the present invention will become more fully apparent from the following description and appended claims, taken in conjunction with the accompanying drawings. Understanding that these drawings depict only typical embodiments of the invention and are, therefore not to be considered limiting of its scope, the invention will be described with additional specificity and detail through use of the accompanying drawings in which:

#FIG. 1 is a front cross sectional view showing a loose tube paved with a ribbon optical fiber bundle in the prior art;

#FIG. 2 is a side cross sectional view showing the loose tube as taken along line A-A′ of FIG. 1;

#A preferred embodiment of the present invention will now be described with reference to the accompanying drawings. In the following description, the same drawing reference numerals are used for the same elements even in different drawings. The matters defined in the description are provided for explanatory purposes to assist an artisan in a comprehensive understanding of the invention, but the invention is not limited to the examples provided. The present invention can be carried out without the matters defined in the description. Also, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

#FIG. 3 is a front cross sectional view illustrating a stiffed ribbon optical fiber bundle in accordance with a preferred embodiment of the present invention, and FIG. 4 is a side cross sectional view illustrating of the loose tube as taken along line B-B′ of FIG. 3.

#With reference to FIG. 3, the reinforced ribbon optical fiber bundle 250 includes a ribbon optical fiber bundle 230. As shown, the 12-fiber cables 210 is coated with a ultraviolet curable resin forming a multilayered ribbon optical fiber 220, and a pair of reinforcing layers 240 disposed at a upper portion and a lower portion of the ribbon optical fiber bundle 230. The the optical fibers 210 is coated at a liquid phase, and later cured when it is irradiated by ultraviolet light.
