Description

Optical cable {Optical fiber}

The present invention relates to an optical cable, and more particularly, to an optical cable capable of easily grasping the installation position of the optical cable and the connection position of the optical connector coupled to the optical cable.

As the demand for the Internet increases and the number of optical cables increases as the number of optical subscribers increases, optical distribution boxes and optical connection boxes are used to easily distribute and connect optical cables from optical networks to each optical subscriber and transmission equipment.

In these optical distribution boxes and optical connection boxes, optical jumper codes are used to properly distribute and connect optical cables introduced from the outside to each optical subscriber and transmission equipment.

The optical jumper cord currently used is constructed by connecting an optical connector to both ends of one optical cord. In order to manufacture such an optical jumper cord, the outer coverings of both ends of one optical cord are stripped for a certain length and connected to each optical connector, and then the outer portion is coated again on the stripped and connected portions to fix the connected portions and to the external environment. It is manufactured so that the optical cord is not exposed.

In the optical jumper cord, the optical cords branched from the optical cables that are introduced from the outside into the optical distribution box and the optical junction box are connected to a connector at one end of the optical jumper cord, and the optical codes from each optical subscriber and transmission equipment are optical jumper cords. It is connected to the optical connector at the other end of the. That is, one optical jumper cord should be used in the middle to connect one optical cord branched from an incoming optical cable to one optical cord from an optical subscriber or transmission equipment.

Such a light jumper cord is inconvenient to find a corresponding light jumper cord for maintenance in a state in which a plurality of light jumper cords are wired when a cable and the optical connector are normally composed of a single color and a failure or error occurs.

Also, because hundreds to tens of thousands of strands of optical cables are arranged on the optical path constituting the optical communication system, a lot of manpower and time are invested in finding a connection location for a specific cable, even though it is a highly skilled and experienced expert. In addition, there is a problem in that a situation in which reworking is repeated very frequently due to errors or errors in connection, as well as having to carry out various inspection equipment.

The present invention is to solve the conventional problems as described above, an object of the present invention is to provide an optical cable that makes it easy to grasp the position where the optical cable is installed and the connection position of the optical connector coupled to the optical cable.

In order to achieve the above object, the optical cable according to the present invention is an optical connector coupled to and detachable from an optical junction box or an optical distribution box, and an operator of the optical cable or optical distribution box has an operator on the surface of the optical cable. , The manager information, the installation location information, the connection location information so as to recognize the installation location information of the optical junction box or the optical distribution box and the connection location information of the optical connector for the optical junction box or the optical distribution box, respectively. A marking portion composed of a plurality of character strings is printed, and the marking portions are spaced apart at regular intervals along the longitudinal direction of the optical cable, are repeatedly formed, arranged in a spiral shape along the optical cable, or on one side of the marking portion. It characterized in that the marker portion of the other side is arranged to be positioned at a position rotated at a predetermined angle along the clockwise or counterclockwise direction around the optical cable.

In the optical cable according to the present invention, manager information, installation location information, and connection location information are printed on the optical cable, thereby reducing the time for an operator to grasp information about the optical cable and the optical connector, and reducing the occurrence of connection or connection errors in the optical cable. There are advantages.

1 is a perspective view showing an embodiment of an optical cable according to the present invention.
Figure 2 is a perspective view showing another embodiment of the optical cable according to the present invention.
3 is a perspective view showing another embodiment of an optical cable according to the present invention.

Hereinafter, an optical cable according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 shows an optical cable according to the present invention. 1 to 3, the optical cable 1 according to the present invention is an optical connector 2 that is coupled to and detachable from an optical junction box or an optical distribution box, the main body including a core, a cladding, and a covering part And, it is provided with a marking portion 10 printed on the surface of the body.

The optical cable 1 according to the present invention can be used by cutting the optical cable 1 to a length required by an operator and combining the optical connectors 2 at both ends.

The marking unit 10 includes manager information 11 such as a communication company or organization where an operator manages an optical junction box or an optical distribution box, installation location information 12 and optical in an area where the optical junction box or optical distribution box is installed. Administrator information (11), installation location information (12), so as to recognize connection location information (13) of the optical connector (2) coupled to the optical cable (1) for multiple connection slots in the junction box or optical distribution box, It comprises an information display unit 15 composed of a plurality of character strings including the connection location information 13, and a marker 17 for marking the start and end of the information display unit 15.

As shown in the figure, the manager information 11 of the information display unit 15 may include a name of a communication company providing communication services, such as SKT, KT, LGT, etc., including English letters and numbers.

The installation location information 12 of the information display unit 15 may be composed of code information allocated for each region for efficient management of an optical access box or an optical distribution box in a communication company, and this code information may be composed of alphabetic and numeric strings. have.
