Improved optical fiber optical cable

Abstract

Disclosed is a fiber optic cable, comprising a central strength member, disposed at the center of the cable, for providing tensile strength; a plurality of inner tight buffered cores disposed in a linear form around the central strength member; a plurality of outer tight buffered cores, twisted in a spiral or S-Z form, for enclosing the inner tight buffered cores; and a jacket, disposed on an outermost circumference of the cable, for protecting an interior of the cable from external environments. The linear form of the inner tight buffered cores enclosed by the outer tight buffered cores, twisted in a spiral of S-Z form thereby providing a structure allowing the fiber optic cable to be maintained in a stable arrangement.

Description

technical field [0001] The invention relates to an optical fiber cable. More specifically, the present invention relates to a fiber optic indoor / outdoor fastening buffer cable. Background technique [0002] Fiber optic indoor / outdoor fastening buffer cables are commonly used for intra-building network applications such as interconnection between a central office and other offices. In general, optical fibers have the advantage of smaller diameters and wider bandwidths compared to metallic cues. The disadvantage of optical fiber is that it is more susceptible to damage not only to its axial tension but also to its transverse external impact. [0003] figure 1 is a cross-sectional view of a traditional fiber optic indoor / outdoor fastening buffer cable. figure 2 yes figure 1 Side view of the fiber optic cable shown. The fiber optic cable includes a central strength member 110 , nine inner fastening buffer cores 120 , fifteen outer fastening buffer cores 130 , outer streng...

AI Technical Summary

Problems solved by technology

[0009] A disadvantage of the fiber optic cables described above is that when the inner and outer fastening buffer cores 120 and 130 are placed in the same orientation, they become messy or have poor flexibility characteristics

Furthermore, another disadvantage is that the production of such fiber optic cables is inefficient due to the complicated production steps
