Description

A fiber optic cable system for checking line number

The present invention relates to an optical cable system capable of easily grasping the line number of the optical core wire for each unit of the optical cable.

More specifically, the optical fiber includes at least one optical unit grouping a plurality of optical cores into a first color coating layer according to a predetermined line color scheme, wherein the grouped plurality of optical cores have a second color having the same color as that of the first color coating layer. An optical cable including a color layer formed at a predetermined interval apart in a longitudinal direction of the color coating layer and the second color coating layer, the color layer being formed in accordance with the color scheme according to the color scheme, and from the image of at least one optical core line to the color scheme. And a terminal for analyzing the line number of the optical line and providing the analyzed line number to a corresponding position of the photographed image.

The optical fiber is made of a core, a clad, a jacket, or the like. The core is made of glass or plastic with high refractive index. The cladding consists of glass or plastic with a lower refractive index than the core. The jacket is made of a material such as plastic as the outermost layer of the optical fiber to prevent moisture abrasion damage and the like.

Optical fiber transmits the signal-coded rays to the internal reflection, which has a wider bandwidth than other wired transmission media, resulting in an excellent data rate. In addition, since the size and weight are small, the supporting structure can be reduced in size and transmitted in the form of light, thereby preventing external interference such as impact noise and crosstalk. Therefore, it is widely used in local area and wide area network, long distance communication, military use and subscriber line.

In general, when using one wavelength for one optical fiber, the data rate is up to 2.5Gbps. However, a technique has been developed to further increase the transmission speed by simultaneously transmitting multiple wavelengths using a wavelength division multiplexing technique.

Recently, the supply and demand for high-capacity digital contents are increasing day by day. Most of this high capacity data transmission is through optical cables. Even if the transmission capacity of an optical fiber is technically increased, there is a limit in capacity, so in some cases, a single core cannot be dedicated to data transmission. In this case, a method of increasing the number of shims is inevitably used.

In addition, although there may be only one optical fiber connecting the mutual regions, it is usually connected to a plurality of optical fibers, it is necessary to connect each optical fiber separately. Typically, the optical fiber is to distinguish the optical fiber by the color of the acrylic coating layer. That is, the color of each core line is distinguished using a color table for each core line defined for each unit. Korean Patent Laid-Open Publication No. 2008-0095459 is a patent document for an optical cable that includes contents that can distinguish core wires through color.

However, the conventional optical cable distinguishes core wires only by color classification. Thus, as the number of core players of the optical cable increases, there is a limitation in that the worker distinguishes the core wires only by color, and in the case of overlapping turning numbers that are displayed in the same color, it is more difficult, and a dangerous situation may occur during operation.

Accordingly, the present applicant is to provide an optical cable system that can easily check the line number for each core line of the optical cable.

In the case of FIG. 6, since the first optical line is 1 for A, 6 for B, and 2 for C, the number X becomes 2 when applied to X = (A-1) B + C. In addition, since the second optical fiber has A of 2, B of 6, and C of 1, the number of turns X becomes 7 when applied to X = (A-1) B + C. In addition, since the third optical line A is 2, B is 6, and C is 4, the number X becomes 10 when applied to X = (A-1) B + C.
